Custom iPhone Application Development Process

1. Idea

The idea comes first. When you formulate what you want from your iOS application, we will help you answer whether this idea can survive the competition in the App Store.

2. Research

The idea has the potential to achieve firm success, so now it’s time to take a closer look at the market: what competitors offer, what niche is suitable for your app, and what competitive advantage you can use.

3. Prototype

A prototype is an essential stage in iOS app development: You and the team see what the app will look like on various iPhone and iPad screens, how users will move around the app, and what should be fixed.

4. Design

Designing is the most creative part of iOS product creation. But despite being full of creativity, this process also needs a lot of working effort. Here we define what the app will look like and what visual experience the users will get.

5. Develop

When diving into the technical side of iOS app development, the Yellow team uses cutting-edge technologies and tools. They are trusted by many specialists and proved themselves to be the right choice for iOS apps.

6. Review

Yellow is a fan of the cross-review process. All the code is reviewed by peer engineers and our iOS tech lead. If necessary, it’s optimized and then passed to QA specialists. It helps us make sure each update is of a high standard.

7. Test

There are plenty of testing types we use for iOS solutions: manual, automated, integration tests, load tests, unit tests, and many more. The Yellow team will help you not get lost in all these types and recommend the most fitting for your project.

8. Launch

When previous stages are successfully finished, we help you release your app in the App Store. Our team can provide you with all the packaging and marketing materials. Also, the Yellow team provides full post-release support and is always there to help you with anything you face.
