TrainerKit

Get faster on the bike you actually ride. Adaptive coaching that reads every ride and tells you exactly what to do next. Plus a calendar to prep for races and trips.

TrainerKit is an adaptive cycling companion for iPhone, iPad, and Apple Watch. Ride indoors with any FTMS smart trainer, outdoors with GPS, or standalone on your Apple Watch.

Daily coaching is sharper and more natural, with on-device Apple Intelligence phrasing that stays accurate and never generic. The Plan tab shows a 4-week outlook with your intensity mix and weekly load, and you can move a hard day to today with one tap when you're feeling good.

New ways to ride: an E-Bike ride type, and Wet Mode on Apple Watch that uses native Water Lock to keep rain off the screen so a downpour can't end your ride. Plus multi-day Training Trips, per-ride Strava bike assignment, and more reliable Bluetooth, iCloud sync, and Strava — your connection now survives a reinstall.
