Flutter/React Native Smart Band App
Budget: ₹1,500 – ₹12,500 INR
I need a single code-base mobile app—built in Flutter or React Native—that pairs over Bluetooth Low Energy with a white-label smart band using the manufacturer’s BLE SDK. I will provide the SDK libraries, UUIDs, and documentation as soon as we kick off. The goal is to compile and ship the same code to both iOS and Android stores.
Core scope
• Implement a smooth pairing/re-pairing flow.
• Pull real-time metrics (steps, heart rate, battery level, etc.) and display them in simple dashboards.
• Store data locally for offline access and render basic charts.
• Support OTA firmware updates exposed by the SDK.
• Produce signed .ipa and .aab builds ready for App Store and Google Play submission, along with clean, well-commented source code.
Acceptance criteria
1. Band connects within 5 seconds and auto-reconnects in the background without draining the phone battery.
2. Data sync succeeds on at least 95 % of attempts across both platforms.
3. UI updates instantly on each new metric received.
4. No critical crashes detected after 24 h stress testing on TestFlight and internal track.
Timeline
I want an initial testable build ASAP and a store-ready release right after we iterate on feedback.
Proposal instructions
Send a detailed project plan explaining:
• your chosen framework and BLE libraries,
• sprint-by-sprint milestones with hours,
• previous BLE wearable apps you have shipped, and
• your strategy for continuous testing and store submission.
I’m ready to start immediately once I review a solid proposal.
