Build the training app you want.

Pick what's on it, pick how it looks, put it on your phone. Your own runs, a coach's engine behind every number. About five minutes, no code.

Free to build and to see your first results. Running now; HYROX, cycling and triathlon next.

A runner's app: morning call, today's session, goal rings
The plan screen: this week's sessions with Move and Ease buttons

Not another tracker.

Strava shows what you did. Your app tells you whether it worked and what to do next.

A verdict on every run

Hit, too hard for an easy day, or missed, and why. Judged against your zones, not an average runner's.

A plan to race day

Built back from your race, sent to your watch. Move a session, ease a week, or build your own in plain words.

Your method, your targets

Canova, Jack Daniels or MAF. Heart rate, pace or feel. Your app follows the way you want to train.

Made yours

Pick from 20+ widgets and 10 looks. Set your own goals and numbers. It's your app, with your name on it.
