One session, every discipline. Synox detects swim, bike and run — and the transitions — automatically, and builds a clean segmented workout without you touching the phone.
A hybrid classifier reads motion, GPS and cadence, smooths it over a rolling window, and only switches discipline when it's truly sure — so there's no jittery flip-flopping mid-race.
Recognises slow, periodic motion with weak GPS — and resumes cleanly when you exit the water.
Falls back to motion when the signal drops, and rejects teleport jumps so distance stays honest.
Detects cycling and running from cadence and motion even with no GPS at all.
