boAt Wearables
Biometric Telemetry & Hardware Abstraction Ecosystem
Architected the core mobile companion engine for India's #1 wearables brand. Built a modular Hardware Abstraction Layer (HAL) to support monthly product launches and high-concurrency vital-signs sync.

The Challenge
During rapid expansion, boAt smartwatches scaled to millions of active users. However, they sourced chipsets from multiple vendors (Realtek, Jieli, Ambiq), each with proprietary, closed-source SDKs. Rebuilding the app for each new model was commercially unviable, and battery limits frequently killed synchronization threads.
Our Solution
CAN Tech designed and built the boAt Wearables companion ecosystem. We architected a common Hardware Abstraction Layer (HAL) in the app to standardize Bluetooth commands (connect, write, sync). We engineered a metadata-driven UI configurator that reshapes the dashboard dynamically based on watch parameters, and implemented a robust background sync daemon.
Technical Architecture
Technical Architecture & Telemetry Data Schema
Smartwatch sensor streams are captured via BLE packets, buffered locally in background SQLite threads, and pushed to the cloud core. This prevents ANR (App Not Responding) errors on budget devices.

Companion Home Dashboard
A unified daily wellness snapshot showing step progress toward a 10,000-step goal, calories burned, active minutes, and blood oxygen — alongside average heart rate trends, a sleep breakdown score, and total sleep duration with bedtime and wake-up timestamps.

Heart Rate Analytics
Day, week, and month views with an hourly bar chart of average heart rate readings, plus min, average, and max statistics — giving users a clear picture of cardiovascular activity across the day.

Sleep Tracking & Guidance
A day/week/month sleep view with a duration ring and bedtime milestones. When no data is synced, the app surfaces a coaching prompt — "Wear your boAt to bed tonight" — encouraging users to wear their watch and aim for 7–9 hours of sleep.
