According to DataReportal, in July 2020, there were 4.2 billion social media users in the world (which is more than half of all humanity), while the number of smartphone users reached 5.22 billion. Impressive, isn’t it? Social media applications have taken up a large part of our life. So many hours a day are now spent on social networks chatting with friends, sharing photos, audio, video, looking through the news, and even offering goods and services.

However, although there are monopolists like Twitter, Instagram, and Facebook on the market, new social network solutions continue to be offered and some of them achieve true success and audience recognition.

In this post, you’ll learn what features they should provide, what purposes they can serve, and how to create your own social media app from scratch. What’s more, we’ll give you some cool ideas and recommendations for the development! Well, let’s start our journey!

What is a social media app?

Before getting down to the topic, we should clarify what a social media application is. Someone can confuse it with a messenger, especially if it has some other features besides message exchange.

A social network is an online service for communicating with people who have similar interests or backgrounds and sharing content between them. The primary goal of any social media is to build connections with others, but today they went way further than this. A modern social network is a platform for sharing opinions and ideas, public debating on urgent topics, maintaining a personal brand, and even making payments and purchases. Also, now it’s a powerful marketing tool.

The most successful social media like Facebook or Twitter have a user-friendly interface, an open opportunity to connect with people all over the planet. In addition, they have something that makes them stand out.

There are several things that make social media apps different from other products and the key ones are content + communications. Look around: almost all social network solutions allow their users to interact with the content - share it, react to it, and discuss it.

Types of social network apps

Now, when we learned the concept of social media, let’s look at the various forms this software might have. Doing so will help identify the most appropriate niche, at which we can gain the most revenue while presenting the greatest value.

  • Relationship networks: Most popular social networks, such as Facebook and LinkedIn, fall into the relationship category. They are created to connect people, enabling them to interact with each other and share information.
  • Media sharing networks: TikTok, Instagram, and YouTube are the most notable representatives of this group. These social-media apps allow users to share media like images and videos.
  • Blogging platforms: With the help of these solutions, people can create blogs, publish and edit content, and manage comments. For example, Tumblr and Medium work like that.
  • Content-only networks: These apps are created to share, comment, look for and save various types of content. Of this type, Pinterest and Wattpad are among the most popular apps.
  • Forums: Participants discuss urgent topics, ask and answer questions, and share insights and experience, as you'll find in Quora or Reddit.
  • Customer review networks: People use this type of app to look through reviews about a certain business or leave one about a company they had any experience with. Services like Yelp and TripAdvisor give this opportunity to users.

Each type of social media is defined by a certain purpose and desired functionality. So, prior to the development stage, you should consider what you want to include in your app and what needs you want to address.

Some best social network apps to learn from

Here are some social networks that already won the audience’s attention:

      1. TikTok

    TikTok is a social media mobile application that enables you to create, edit, share, and watch short videos. The app allows video streaming and employs AI to provide a personalized video feed based on user likes, shares, and views.

    The app was initially released in 2016 but boomed in popularity during the lockdown time in 2020. In the first quarter of the pandemic year, the number of downloads reached 315 million compared to 199,4 at the end of 2019. Also, in January 2021, TikTok had 689 million users worldwide. How this app made it so far? The answer is pretty simple: it offers cool features to entertain users, focuses on their preferences, and has an intuitive design.

      2. Instagram

    Visual content is everything. The greatest example of social media based solely on images and videos is Instagram. Founded more than ten years ago, this social network developed into a multifunctional platform. Now it’s used not only by regular users but also by brands and enterprises that communicate with their audiences like equals.

    At the beginning of the year, Instagram reached more than 1,2 billion active users and become of the top 10 most visited websites, even though it mainly focuses on a mobile app.

      3. Facebook

    Despite being one of the oldest social media, Facebook still holds its position as the most popular social media among users. Simple design and extensive functionality contribute a lot here. However, the statistics may change since the younger generation now prefers more trendy social networks.

    The main directions for creating a social media app

    Social networks can serve various goals, from meeting new people and posting jobs to promoting goods and launching marketing campaigns.

    There are so many ideas to utilize take from other products: text and video blogging, live streaming, advertising, personalized news feeds, and a lot more. We recommend you focus on one thing and then extend the project. So, here are the three main goals of social network app development, we'd like to highlight:

    1. Solve the problem(s) of a narrow-focused audience–building a social network application that adds value to some specific group of people, e.g. dog owners, art lovers, professional photographers, or retired people. Imagine a social media app that allows dog owners to agree to walk their dogs together, find someone who will walk a dog, or new dog owners. Choose your audience and think about how you can facilitate their life.
    2. Implement an idea–you can join people or their specific groups around some product idea. For instance, by location, as we did in our SpeakFree mobile app. Or you can enable users to find the company to go to quizzes and exhibitions or create their own events.
    3. Join people under the unifying topic–making a social media app that unites people under their interests. The focus here is made on content. Imagine, for example, a social media solution for sports lovers that allows users to discuss matches and competitions, publish interesting content about sports, fitness, healthy lifestyle, etc.

    Top features of social media applications

    When building a social network application, you should solve what features it would possess. Though there are many cool things you can include, you have to define what your audience really needs. In addition, decide what will differentiate your app from its competitors. Since competition is fierce, you should provide true added value to your users.

    📌User profile

    A user profile generally consists of a user photo, first name and last name or nickname, and such information as country, city, age, gender, and birth date. Depending on the app objectives, you can also put the “About me” field, education (faculty, university, courses), interests, hobbies, achievements, and so on.

    social app profile


    Likes allow users to positively react to content. In some cases, product owners also integrate dislikes in order not to allow bad content to take high positions and its owners - to have many points or bonuses. At the same time, content that has a high number of likes and no or few dislikes can gain extensive promotion, audience love, sometimes - even money (e.g. Steemit). The examples of apps that have both likes and dislikes are Reddit, Steemit, and YouTube.

    social app likes


    Depending on the app goals, users can look through the news of their friends or business news, or news of the groups they’re subscribed to, etc.

    social app news feed


    Some applications use Artificial Intelligence to personalize the news feed. How does it work? AI analyzes your page, personal information, interests, activities, and tailors the feed accordingly. By implementing this feature, you’ll add value to your audience and win their love.

    📌Content sharing

    Ensure content (file, audio, video, image) sharing opportunities: enable users to upload content, share it in chats, messages, and news feed, create posts, and more. Reddit and Tumblr, for instance, allow sharing links: a user can put a link without writing any description - the system automatically forms a preview.

    social app share


    Communication is the core of social network apps. Provide your users with the ability to chat with other people. Implement private messages, private and group chats. You can even integrate encryption so that your users can be sure that their personal data won’t be viewed, used, or stolen.

    social app share


    People love discussing content no matter whether it’s music, video, business, technologies, commercial news, or just pictures of nature. Therefore, if you build a social media app, include the commenting mode.

    social app comments


    Offer your users the ability to search for content by keywords. If you make a social media app for photo collectors and photographers, it should have photo categories and image search.

    social app search


    Adding friends or creating circles is an important addition to chats and instant messaging. Will it be convenient for your users if they have to look for a friend among all the app users each time that they want to communicate? Of course not! This feature is no less important, especially if user communication is the core of your product.

    social app friends

    📌Collections and subscriptions

    Have you ever encountered a situation when you enjoy some content/profile and want to be aware of the news? We believe that the answer is yes. There are plenty of examples that come to mind: user profile subscriptions (Instagram), group and channel subscriptions (Facebook, LinkedIn, Reddit, YouTube), interest collections (StumbleUpon (now Mix); Google Plus - although it was closed recently, the idea to use collections was pretty good).

    social app subscription


    Geolocation enables you to see users near you, mark a place on a photo (address, city, country), and more. This feature is a must-have for dating applications.

    social app geolocation


    A basic product feature that exists everywhere and seems to be irreplaceable but should be minimized. Allow your audience to use most of the app functionality without registration to offer more convenience and privacy.

    social app sign up

    📌Push notifications

    Users like it when they’re instantly notified about new messages, requests, and followers. And they appreciate it when there is the possibility to customize alerts: choose the time for receiving notifications, turn them on, and turn them off.

    social app push notification

    Certainly, it’s not necessary to integrate all of these features. Take only those that will help you solve user tasks and ensure an amazing user experience. Considering other features, you can also provide the ability to invite friends to install your product, create groups and communities, and use emojis and stickers.

    Moreover, you can implement a feature of facial recognition and emoji creation based on your face. Such a cool function is great in a social media application that focuses on entertainment and communications.

    Main stages to make your own social media app

    Have a cool app idea and the opportunity to implement it? Wonderful! It’s time to find out what steps your product should pass before coming to life. Like any software project, social media application development embraces 7 stages:

    Stage #1: Product idea and requirements formulation

    If you decide to create a social network application, you should define how it would help your users, what tasks it will solve, what functionality it will provide, what makes it stand out from the competitors, and much more.

    Detailed requirements are written in the technical specification and can include a number of things, from design, brand book, and a description of what and how the product should behave regarding the app performance, infrastructure, and software supported versions. But don’t be afraid, social media app developers will always help you!

    Stage #2: Wireframe and prototype creation

    Wireframing is an important stage of a social media app design as it enables both the customer and developers to create and imagine the app skeleton. Due to wireframes, you not only get a structural product view but also establish a basis for its future design.

    Then, designers make a clickable prototype to visualize how the future application will act and what it will look like. What’s more, you can use it to test your idea on the target audience.

    Stage #3: Work planning

    When the software requirements and project vision are clarified, and the prototype is created, you need to plan the work including the development tasks, duration, and budget. At this stage, you should also think about the best ways to implement the product.

    Stage #4: Design

    Now it’s not enough just to create a cool modern design. You must provide a seamless user experience and personalization. Make your design clean, beautiful, and intuitive so that people use the app even without thinking.

    Before developing a social media app design, take a look at your competitors–what and how they make. In addition, check out the software design trends. A perfect way is to catch the wave and make your product ahead of time.

    Stage #5: Engineering

    Once the application design is completed, the development part begins. Here, you should think about the app architecture, technology stack, operating systems, and ways of creating the app.

    We recommend starting with MVP (minimum viable product) development–implement only the key functionality, ideally–just one essential feature that solves the user’s problem. This approach will allow you to test the app on the audience, collect and measure user feedback, and add new features accordingly. By choosing this way, you will reduce costs, quickly get a working solution, validate the idea, and tailor the product to the needs of your users.

    When building a social network application, take care of its scalability, maintainability, and high load support. Integrate an administrator panel so that admins can manage users–segment them, filter, and search (e.g. by name, by email, by ID), and content–remove offensive and threatening content, block users who post it, etc.

    Stage #6: Testing

    Testing plays an important role in social media application development. Testers investigate the product, find bugs, and ensure that the result complies with the requirements, from the app functioning to the number of screens. High quality is impossible without diligent testing, so pay special attention to this stage.

    Stage #7: Launch

    A social network app is published on the App Store, Google Play, and alternative stores if needed.

    The key trends of social media application development

    1. Privacy

    It seems that, today, the whole world is obsessed with privacy. Users hate filling out multiple fields and sharing too much private data. They want to have the ability to use the app without registration or at least without providing a lot of information. Therefore, if you want to collect some user data, ask their permission and explain why you need it.

    In addition, you should ensure high security as there is a risk of password cracking and data theft. Therefore, take care of your users by setting up strong reliable passwords.

    2. Audio and video support

    When building a social network application, integrate audio and video support. Let your users upload, share, store, post, and repost audio and video files. You can even create your app around video–like YouTube did–or make video creation and sharing the main feature by the example of TikTok. You should also take advantage of modern high-speed mobile Internet and live streaming–it will add more value to your social media solution.

    3. Visualization

    Focus on beautiful content visualization and make your app stand out from others. To do this, investigate your competitors, discover what people enjoy, what they don’t like, and what they’re fed up with, and then try to predict the upcoming design trends.

    Remember that the app icon is the first thing users see. Make it bright and attractive so that users would want to click it. You should also ensure that the icon stands out among the rest. Did you notice that there is too much blue? Twitter, Facebook, LinkedIn... Maybe, you should choose something else?

    4. Voice messaging

    Voice messaging–sending recorded or converted from a text voice messages–is trending. Although in some parts of the globe it’s just being introduced, for others, voice chats have long fallen into a habit.

    In China, for instance, mobile apps can’t offer the keyboard with Chinese, since there are thousands of hieroglyphs that simply don’t fit on a small screen. “It’s a phenomenon that has just hit our shores lately, but it’s been huge in China over the years,” says Dr. Benjamin Cowan of University College Dublin’s school of information and communication studies.

    Alex Hart, who works at a Chinese company with US and European customers, adds: “Most of our internal communication occurs via WeChat”. WeChat is the Chinese alternative of WhatsApp that provides extensive voice messaging support.

    So ensure to integrate voice messaging into your application to let your users communicate with no text input. It will help you ensure a seamless user experience and keep pace with the trends.

    5. Short-lived content

    The integration of short-lived or self-destructing content is becoming a trend of social media app development. Snapchat and Instagram have already adopted it in their products. You may have already noticed that Instagram Stories are very popular and enjoyed by users.

    Posts that contain this type of content can be set to expire in an hour, day, or week–as a user desires. Since self-destructing messages ensure a higher level of privacy and perfectly suit urgent and intimate issues, users appreciate having them in the app.

    Technology stack

    The exact list of technologies and tools depends on the particular specifications of the project, available budget, and platforms you want to release it on. However, it’s still possible to predict the most crucial solutions that will get in hand while building a new social media app.

    An approximate tech stack for a social network will include:

    • Programming language: Swift, Kotlin, Node.js
    • Networking: Alamofire
    • Framework: Express 4
    • Database: MySQL, PostgreSQL
    • Chat: Twilio, PubNub, Socket.io
    • API: Swagger
    • Push notifications: FCM
    • Geolocation: Google Maps
    • Storage: Amazon S3
    • Search: Elasticsearch

    Monetization strategy

    Creating a social media app can be beneficial for businesses and users. Not it’s time to think about how to make it profitable. The most common and proven models to make money out of social media:

    📌Advertisements. The easiest and the most common way to monetize a social network is to give businesses an advertising platform, as Facebook and Instagram did. But be careful with ads: they all should be relevant to users and not be annoying.

    📌Freemium. If something has value, people pay for it more willingly. If you want to implement premium profiles or subscriptions, be sure that your offer is not just unique, it’s exceptional.

    📌In-app purchases. Another popular way to make money out of the app is to create not advertizing but merchandising platform allowing users to buy directly in your social app. Instagram is a great example of implementing this way of monetization.

    📌Venture capital. Companies like Twitter started from raising huge venture capital. This way can be applied if you want to sell your app to a larger enterprise.

    Crucial metrics for social media apps

    Okay, the app is finished and makes money. Now, how you can track its performance and understand the bottlenecks to improve?

    Here is the list of metrics to pay attention to:

    • CPI & CAC. CPI (Cost Per Install) is with total ad spends divided by the number of installs. CAC (Customer Acquisition Cost) shows the overall marketing efforts needed to attract a potential customer.
    • User activation is the number of users compared to the total number of downloads.
    • Churn rate, or customer retention, measures how many customers return for another visit. This metric applies only to existing customers.
    • User engagement is a number of target actions taken in the app. A target action may vary depending on what your goals are.
    • Burn rate shows how much money you invest in your product monthly including, for example, staff and marketing costs.

    These KPIs will allow you to see how your social network is doing and fix the issues quickly if they appear.

    Cost to build a social media app

    The cost of creating a social media app varies depending on a lot of factors like the desired functionality or the team’s rate. Also, the way of building it matters. If you want to opt for a SaaS or CMS solution, it will show itself faster and less costly than an open-source tool.

    If you’re considering building a native social media app, then you will need a backend that can take months to develop and a client-side part for iOS, Android, or both.

    The approximate costs for development can range from $90,000 for one platform and $155,000 for two platforms.

    Creating a social media app: Our practical experience

    We have experience in many areas but social networking takes a large part of it. The industry is large and we’re happy to have truly interesting cases in our portfolio. There are several great social media projects that we successfully delivered. Take a look!


    Famlicious is a mobile chat application for families that allows people to get closer to their relatives. It includes family chats, family member profiles, and user timelines. However, the most remarkable feature is the family trees that have a dynamic nature.

    What differentiates Famlicious from other social media apps is the unique way of building family trees. When a new family member is registered on the app, they are added to the related tree. As a result, family trees are automatically updated and all the connections can be seen on the app screen. You can learn more about Famlicious development in its case study.


    We built SpeakFree, a location-based mobile application that enables users to find and interact with interesting people around them. The app supports text, photo, and video messages, allows content sharing, and has no sign-up. SpeakFree is a spam-free anonymous group chat offering simple and private communications.

    Interestingly, 4 years ago Syrian refugees used the application for communication with each other and mutual assistance. It was in Germany at the time when they had a refugee crisis. We didn’t expect this situation which was even covered in the German news.

    Closing thoughts

    Social network solutions have transformed the way we communicate, interact with the content, and look for different things, e.g. job, services, investments, relationships. As a result of their widespread adoption, new jobs like a blogger, SMM manager, and PPC marketer emerged and gained popularity.

    Although social media applications often bring a lot of junk and false content, they can do a lot of good. Many children and animals are saved with the help of social media, refugees and the poor receive assistance via social networks, people come together to help victims like it was during Hurricane Katrina which made landfall in Florida and Louisiana.
