I need a production-ready attendance tracker for both iOS and Android that relies exclusively on the device’s fingerprint sensor. Staff will open the app, place a finger on the reader, and their check-in or check-out will be logged immediately to an online database—no offline mode or later syncing is required. A separate web-based backend must let me create, edit, and disable users while giving me clear attendance reports I can filter by date range and export to CSV or PDF. Real-time dashboards are welcome, but push notifications or other extras are not in scope for this phase. Deliverables • Store-ready iOS and Android apps using the native biometric APIs • Secure API layer connecting the apps and backend • Admin panel with role-based access, user management, and attendance reporting • Full source code with deployment instructions Acceptance criteria – Successful scans appear in the backend instantly with user, timestamp, and location – Failed or spoofed scans are rejected and logged – Admin can generate daily, weekly, and monthly reports and export them Build it in Flutter, React Native, or native code—whatever you prefer—paired with a maintainable backend such as Node, Django, or Laravel. Just keep the code clean and the setup steps clearly documented so I can deploy and maintain the system without surprises.
