overtrain

Train without an account, without a subscription, and without a cloud you didn't ask for.

overtrain is an indoor cycling app for riders who just want to plug in their trainer and get on with the work. It pairs with your FTMS smart trainer over Bluetooth, runs the workout, and writes a .fit file you can upload to anything - intervals.icu, Strava, TrainingPeaks, or nowhere at all.
