What devices does it work with?

Currently Apple Watch on iOS. We are expanding to Garmin, Polar and additional wearables. Any Bluetooth heart rate monitor will work.

How do I earn Credits?

Your heart rate is tracked during workouts. Time spent in each effort zone earns you points. Points convert to SENOS Credits. The harder you work, the more you earn.

How SENOS works

SENOStracks your heart rate during workouts and awards Credits based on effort intensity. Three zones — light (1 Credit/min), moderate (3 Credits/min), and high intensity (4 Credits/min) — are calculated from your personal max heart rate. Credits are redeemable for rewards from global brands.

Built on science

How does the SENOS zone system work?

SENOSuses our own formula — the most validated heart rate model in sports science — to calculate your personal maximum heart rate. Your zones are unique to you. A 50-year-old working at their limit earns just as much as a 25-year-old at theirs. Effort is the only currency that counts.
