Ride by feel. Train by heart.
Your heart rate zone fills the screen while you ride, so you can hold the right effort without checking numbers. Records with GPS, syncs with Apple Health and Health Connect.
Five zones. The only colour in the app.
Set from your age or your known max, updated live as you change it. Everything else stays black on white, so the one colour on screen always means effort.
See where the ride got hard.
After each ride the route is coloured by heart rate zone. Tap any point for heart rate, speed and climb, plus 5 km splits.
Map first. One button. Everything else when you need it.
Built natively for iPhone and Android.
Liquid Glass controls on iOS 26, Material surfaces on Android. Same zones, same rides, same data you own.
Your heart stays on your phone.
Health data is read on your phone and never sent to our servers. Every permission is explained before the system asks, and each one can be skipped.
Everything you need to ride. Pro for the deep dive.
