Introduction

Chatr reimagined the messaging experience by blending contemporary design with cutting-edge technology. Launched to leverage the innovative features introduced in iOS 14, Chatr is not just about messaging; it’s about redefining communication. Designed with a sleek, modern touch, Chatr integrates seamless animations to deliver an exceptional user experience, ensuring every interaction feels intuitive and engaging.

Open-Source

Embracing the spirit of open source, Chatr’s codebase is open to developers worldwide, consisting of three main components:

• iOS Client: The primary interface for users, developed with SwiftUI to utilize the latest user interface innovations from Apple.
• ChatrUI: A set of reusable SwiftUI components and utilities that streamline the development of the app’s user interface.
• Heroku Backend: Manages backend operations such as data handling and real-time synchronization, ensuring that the application performs reliably and efficiently.

These repositories are hosted on GitHub, allowing developers to contribute to the project, suggest improvements, and use the code for their own customized versions of the app. This open-source approach not only enhances the app’s quality through community input but also promotes transparency and trust in the app’s functionality and security.

Core Features & Technology

Built with SwiftUI and integrated with both UIKit and AVFoundation, Chatr offers a robust platform for multimedia messaging. Its design focuses on fluidity and responsiveness, making communication both enjoyable and efficient. Key technologies include:

• Realm Database & CoreData for efficient local data storage.
• Firebase Suite, ConnectyCube, & UploadCare for scalable backend services.
• In-App Purchase Subscriptions and Apple Push Notifications to engage users and offer premium features.

Enhanced User Experience

Chatr is deeply integrated with multiple iOS services to provide a seamless user experience:

• Photos and MessageUI enable easy media sharing.
• Contacts and Core Location facilitate context-aware messaging.
• Giphy API allows users to express themselves with GIFs.

Conclusion

Reflecting on the development of Chatr, this project has been a significant milestone in my journey as a developer. Creating Chatr allowed me to dive deep into the latest iOS technologies and design principles, blending advanced technical frameworks with a user-centric design approach. Making the project open-source was a strategic decision, allowing others to view and learn from the code.

This experience was enriched by developing a full stack solution, including a website, a robust backend on Heroku, and a fully functional native iOS application, designed with custom design system that enhanced the overall user experience.

Chatr was actively tested on TestFlight from November 2019 through February 2021, providing real-world feedback and insights that were invaluable in refining the app. However, the decision to deprecate Chatr was driven by the increasing demands of codebase upkeep and the growing server costs, which made the project unsustainable in the long term.

Through Chatr, I’ve not only developed a functional and aesthetically pleasing messaging app but also honed my skills across the entire technology stack—an invaluable experience that shapes my approach to technology and innovation.
