Owl Smart Ring
Reliable alarms and timers in a discreet ring-sized wearable with multi-day battery life.
Mission Overview
A smart ring engineered for alarms and timers — discreet haptic alerts and precise countdown timing in a finger-sized wearable.
Challenge
Deliver dependable alarms and timers in a ring-sized enclosure while holding multi-day battery life and a seamless mobile experience. Teams that treated scheduling, haptics, firmware, and the companion app as separate workstreams created missed alerts and unpredictable timer drift.
Constraints
- Strict power budget on a compact wearable form factor
- On-time haptic alerts without constant radio activity
- Cross-platform mobile sync for alarm and timer configuration
Architecture Strategy
Low-power MCU → On-device alarm/timer scheduler → Haptic motor → BLE transport → Cross-platform mobile app.
- MCU owns schedule logic, haptic delivery, and radio wake windows
- Mobile app configures alarms and timers — device executes autonomously offline
- BLE sync reconciles schedule changes without draining the cell
Engineering Stack
Engineered ultra-low-power firmware with precise alarm scheduling, haptic alert delivery, and a resilient BLE sync layer that keeps the companion app aligned without compromising battery life.
Guided Trajectory
- SCOPE
Challenge
Scoped alarm, timer, and battery requirements before hardware lock.
- MAP
Architecture
