The 100% Free, Open-Source UPI Payment Soundbox
RupeeRing turns any Android device into a smart payment announcer. Designed for merchants, freelancers, and small business owners, it listens for incoming payment notifications from major UPI apps and announces the amount out loud—just like a physical soundbox, but without the subscription fees, hardware costs, or intrusive ads.
- 100% Free & Open Source: No hidden charges, no premium tiers.
- Zero Ads: A clean, distraction-free interface built for fast-paced retail environments.
- Universal UPI Support: Works seamlessly with PhonePe, Google Pay, Paytm, BHIM, BharatPe, Navi, and other standard UPI apps.
- Privacy First: RupeeRing operates locally on your device. It only reads payment notifications to trigger the Text-to-Speech (TTS) engine and does not collect or transmit your financial data.
- Customizable Alerts: Adjust the volume, voice, and language (English, Hindi, Malayalam, Kannada) of the announcements.
- Local Transaction History: Includes a filterable dashboard to browse the last 30-days of payments out-of-the-box.
- Framework: Flutter / Dart
- Core Functionality: Android NotificationListenerService & Shared Preferences Storage
- Data Layer: SQLite Database (sqflite)
- Audio: Native Text-to-Speech (TTS) implementation via flutter_tts
