TrainerKit
Health & Fitness
Free
Your complete indoor and outdoor cycling companion. Smart trainer workouts, GPS rides, training plans, and Apple Watch heart rate in one app.
TrainerKit is your all-in-one cycling training app for iPhone and iPad. Connect your smart trainer via Bluetooth for indoor rides, or head outside with GPS-powered outdoor
workouts and free rides. Live power, cadence, speed, and heart rate metrics keep you dialed in wherever you ride.
Indoor Training
Connect your smart trainer and ride structured workouts with automatic resistance control. Simulate real-world GPX routes with grade changes and surface types, or free ride at
your own pace.
Outdoor Rides
Take structured workouts outside with GPS tracking and audio coaching. Or start an outdoor free ride and just pedal. Battery-smart GPS accuracy adjusts automatically based on
your speed.
Training Plans
Follow periodized training plans that adapt to your progress. Track completion on the calendar and let the plan adjust when life gets in the way.
FTP Testing
Three built-in protocols — 20-minute test, ramp test, and 8-minute test — with automatic FTP detection so your zones stay current.
Apple Watch Integration
Pair your Apple Watch for live heart rate delivery during indoor rides — no chest strap needed. Haptic coaching alerts keep you in the zone without looking at the screen.
Multi-Athlete Support
Multiple riders, one app. Each athlete gets their own FTP, power zones, training plans, and ride history. Switch profiles instantly.
Stay Connected
Auto-upload completed rides to Strava and Intervals.icu. Export industry-standard FIT files. Save workouts to Apple Health. Sync ride history and training plans across your
devices via iCloud.
