Android Recharge & Bill Pay App
Budget: ₹12,500 – ₹37,500 INR
I need a full-featured Android application that lets users top up their mobile phones, recharge DTH subscriptions, and pay routine utility bills—all in one place. Smooth, secure sign-in is mandatory, so the sole authentication flow will be phone number verification followed by an OTP.
The core work involves:
• Building a modern Android UI that guides users quickly from login to successful payment
• Integrating reliable recharge / payment APIs for prepaid mobile, DTH, and multi-bill categories
• Adding a payment gateway that supports cards, UPI, and wallet options common in India
• Implementing a robust backend (custom or Firebase) to store user profiles, transaction history, and OTP logic
• Delivering clean, well-documented source code plus a signed release APK
Acceptance criteria
• Phone-number-only login generates and verifies OTP within 20 s
• Successful real or sandbox transactions for all three service types
• Error handling and status updates (pending, success, failed) clearly visible to the user
• Code compiles in the latest stable Android Studio and passes Play Store checks
If you have prior experience with recharge APIs and OTP-centric flows, I’d love to see your work and discuss timelines.
