Android Text Chat App Development

Job ID: 40348845

Budget: $250 – $750 USD

I’m building a focused chat experience for Android that does one thing very well: real-time text messaging. I need you to design and code the entire application, from a clean, intuitive UI to a secure, scalable back end. User onboarding, contact search, message history, and push notifications should all work seamlessly. Voice/video calling and file sharing can wait for a later phase—right now reliability and speed for plain text are the priorities.

Please use a modern Android stack you’re comfortable with—Kotlin paired with Firebase, Supabase, or another real-time database is fine, as long as messages stay encrypted in transit and the solution can grow to millions of users.

Deliverables
• Release-ready APK and full, well-commented source code
• Basic README or setup guide so I can build and deploy updates locally

Let me know your estimated timeline, any similar chat apps you’ve already shipped, and how you plan to handle encryption, notifications, and offline caching. I’m ready to get started as soon as I find the right fit.
