Authentication & log in

Users register via an SMS verification code sent to their mobile phone or via email. They must then create a 4-digit PIN number for accessing the app.

Contact cards

When a user enters their profile, they can create and share one or several business cards where they indicate their occupation, contact details, address, and social media.

Blast messages

BlackBird can create group chats, but if a user needs to send a message to multiple people individually, they can use Blast messages and create drip campaigns.

Hybrid development approach

The chat functionality and encryption algorithms were written in Swift which is a native iOS language. However, other features including BlackBird’s UI were written with the help of cross-platform React Native. To make both parts work together smoothly, we created a bridge that allows the cross-platform part to communicate with the native one.

Challenges and Solutions

Enhanced security

Problem:

The client wanted BlackBird to have the utmost level of security. Specifically, they requested that all personal information and chat history contained in the app should not be accessible to any third-party service.

Solution:

Our team implemented several options of login so users can choose what they trust the most: Face ID, two-factor authentication via SMS code, password, and PIN number. Also, we created an end-to-end encryption algorithm for messaging so all information is protected.

Deep linking implementation

Problem:

Users should be able to invite friends to the app and share contacts and contact cards with other people. To achieve this functionality, we needed to implement deep links.

Solution:

We integrated deep linking via the React Native app.
