The On-Ice Scout: How Time On Ice Detects Your Shifts
Time On Ice uses a proprietary motion analysis algorithm called the On-Ice Scout. It runs entirely on your Wear OS watch — no phone connection required — and monitors your movement patterns in real time.
Ice skating produces a distinctive motion signature: rhythmic lateral acceleration bursts, minimal vertical bounce compared to running, and high angular velocity through crossovers and turns. The On-Ice Scout is tuned specifically for this pattern.
When you step on the ice, the motion profile changes within seconds. The app transitions your watch face from Bench mode to On Ice mode automatically — no input from you required.
When you return to the bench and sit down, the same process works in reverse. The shift is logged, the timer stops, and your watch quietly prepares for the next shift.
