TrainerKit
Health & Fitness
Free
Ride indoors or out. Structured power workouts, GPS outdoor rides, enduro racing mode, Apple Watch standalone — your complete cycling training platform.
TrainerKit is a complete cycling training app for indoor smart trainer workouts and outdoor GPS rides — on iPhone, iPad, and Apple Watch.
INDOOR TRAINING
Connect your smart trainer via Bluetooth for structured power workouts, GPX route simulation with terrain resistance, and free riding. ERG mode holds precise power targets. Six surface types add realistic rolling resistance to virtual routes.
OUTDOOR RIDES
GPS-tracked free rides and structured outdoor workouts with audio coaching. Barometric altimeter for accurate elevation. MTB-optimized GPS that doesn't snap to roads — perfect for trails. Three map styles: hybrid, satellite, and standard.
ENDURO MODE
Alternating liaison and stage laps designed for mountain bike race training. High-intensity stages with recovery liaisons between them. Uploads to Strava as Mountain Bike Ride with color-coded laps in your ride history.
APPLE WATCH — STANDALONE & COMPANION
Ride with just your Apple Watch. GPS tracking, power meter and cadence sensor support, structured workouts from your training plan, manual lap marking, and a 5-screen ride dashboard. Rides sync automatically to iPhone and iCloud. In companion mode, your Watch displays live metrics from your indoor trainer session.
STRUCTURED TRAINING
50+ built-in workouts or create your own. Periodized training plans that adapt when life gets in the way. Visual calendar with weekly volume tracking.
RIDE HISTORY & ANALYSIS
Per-second power, HR, cadence, speed, and elevation graphs. Route maps for outdoor rides. Lap breakdowns with normalized power, TSS, and intensity factor.
SYNC EVERYWHERE
iCloud syncs ride history, training plans, workouts, and athlete profiles across all your Apple devices.
STRAVA & INTERVALS.ICU
Auto-upload rides as FIT files immediately after you finish.
SENSOR SUPPORT
FTMS smart trainers (Wahoo, Zwift Hub, Tacx, Elite, Saris, and more), standalone power meters with calibration, heart rate monitors, and cadence sensors. Custom nicknames for every sensor.
