U.S. HealthTech Wearables Startup boosts BLE connection success to 97% with TechBlocks

The customer, a U.S. healthtech wearables startup, faced significant scaling challenges due to an unreliable companion app, unstable Bluetooth connectivity, and risky over-the-air firmware updates. These issues with their clinically validated wearable patches drove up support costs and threatened user trust. TechBlocks was engaged as the end-to-end engineering lead to modernize the platform.

TechBlocks rebuilt the companion app for stability, hardened the OTA firmware update process, and implemented robust QA frameworks. This solution delivered a 97% connection success rate, eliminated app crashes, and reduced firmware validation time by 70%. The overall release cycle accelerated sixfold, enabling the client to scale confidently with a reliable, production-grade product for their users.
