Use high-quality continuous ECG-grade heart rate and breathing data to stay at the intended training intensity and avoid drifting out of key zones.
Track recovery and physiological strain trends to balance training load and reduce the risk of overtraining.
Get responsive heart rate data that reflects rapid changes in effort during climbs, intervals, and hard efforts.
Reliable ECG measurements during sweat, movement, vibration, and long rides.
Use HRV trends to understand readiness and optimize when to push or recover.

Chest-based ECG captures a more reliable signal during intervals, sweat, and high movement, so heart-rate accuracy remains stable as intensity rises.
Track HRV trends at ±1ms precision to better understand fatigue, readiness, and adaptation across training blocks.
Capture continuous heart and performance data across running, cycling, rowing, hiking, and more.
VT zones are training zones defined by ventilatory thresholds, which reflect key shifts in energy production during exercise, rather than estimated heart-rate ranges.
Track VO₂ Max changes over time to see whether your training is improving aerobic performance.
Receive vibration alerts when heart rate moves outside your set zone thresholds.
See how hard the cardiovascular system was working during a session for a clearer view of effort and physiological demand.
Track cumulative exercise load over time to keep effort, recovery, and progression in balance.
See the physiological stress imposed by a session to better judge its immediate recovery demand.
Review pace, distance, duration, and related session data alongside heart-based metrics for a complete view of performance.
Add notes and tags to sessions to better interpret how routine, behaviour, and context affect performance.
View ECG data alongside route mapping to interpret cardiac response across changing terrain, pace, and effort.
See how prepared the body is for training on a given day, so intensity better matches current condition.
Track sleep stages and consistency to better understand recovery quality over time.
Track physiological stress over time through HRV and related signals to better understand overall recovery state.
View live ECG during activity and capture continuous recordings for a complete view of cardiac activity over time.
Download ECG data in PDF, CSV, or EDF formats and share it with a coach or healthcare professional when needed.
