On your wrist

Your data, exactly where you want it

24 data fields across five grid layouts. Pick a dense 4×2 for racing or a big 2×2 for an easy long run. When it's time to lock in, focus pages give heart rate, pace, or power a full screen with live zone context.

Review that actually explains the run

Scrub the map and every chart in sync. Tap a spike in your heart-rate line and watch the map jump to that exact point on the route. Splits, HR-zone distribution and post-run analysis turn raw data into actionable insights.

Train with intent

Know if today is a push day

Training load (CTL/ATL/TSB), VO2max trends, a race-time predictor and a daily readiness score pull together into one picture. "Should I push hard today?" gets a real answer, not a guess.
