Paid Messaging and Calling App

I’m building a mobile application for both iOS and Android that combines real-time text chat, crystal-clear audio calls, and HD video calls—similar to WhatsApp, but on a paid model. Users will register, choose a plan, and pay through Stripe. The same payment system will also let me transfer earnings to internal staff accounts.

The project covers everything from UI design and backend setup to final store submissions. I’ll provide brand assets and rough wireframes; you’ll translate them into a polished, production-ready experience with end-to-end encryption, contact syncing, push notifications, and a lightweight admin portal for user, plan, and payout management.

Core deliverables
• Native (or cross-platform) iOS & Android apps ready for App Store and Google Play
• Secure text, audio, and video communication with read receipts and call history
• Fully integrated Stripe workflow for subscriptions, one-time purchases, and staff payouts
• Admin dashboard to monitor users, traffic, revenue, and balances
• Complete, well-documented source code and a brief hand-over session

Acceptance criteria
1. Messaging, calls, and payments function smoothly on current OS versions.
2. All communications are end-to-end encrypted.
3. Apps pass App Store and Play Store reviews on first submission.
4. Stripe transactions settle correctly in both test and live modes.
