Record rides with your phone and Bluetooth sensors, control your smart trainer in ERG mode, follow structured plans, and understand your fitness at a level most apps don't reach.
Record outdoors with the phone's GPS and your Bluetooth sensors simultaneously, or import your full Garmin history as .fit files. Every metric stays on your device.
Connect any FTMS-compatible smart trainer over Bluetooth. MatchesLeft drives ERG mode automatically — hit every interval's exact target wattage without touching a dial. Indoor or outdoor, your choice at ride start.
MatchesLeft models your anaerobic reserve, estimates lactate thresholds from DFA α1, tracks your fitness curve, and tells you what kind of rider you are — and where you're getting stronger.
Try every feature on real rides. Keep going only if it earns its place on your bars.
Subscriptions are billed through Google Play and the App Store. The free trial starts on your first ride.
