The app
Built for a tablet on the handlebars first, and a phone second. Every screen below is the shipping app on an 11-inch iPad — no mockups, and no numbers we made up. Each one follows your system theme, so you are seeing it the way you would run it.
Home
One screen answers the only question that matters when you clip in: what am I doing today. The suggestion reads your current form rather than a calendar — carrying load gets you an endurance ride, not intervals.
Home — the suggestion, your last activity, and the week so far.
A session running
ERG holds the target through every interval, so the only job left is turning the pedals. Power, target, cadence and heart rate stay large enough to read from the saddle, with the profile filling in behind as you ride it.
Warm-up of an endurance session — 168 W against a 169 W target, ERG on.
The AI coach
Ask for a session in plain language and it builds one, then keeps editing it while you talk. Here it swapped the steady endurance blocks for five sweet-spot intervals inside the same hour — the profile, TSS and calories all update with it.
"Add more intervals." — and the session is rebuilt around the same hour.
FTP testing
Ramp and 20-minute tests are built in. The result is offered for review rather than written silently, and every workout rescales once you accept it.

Real roads
Ride a real route and the trainer follows the actual gradient, with the map tracking where you are and the profile banded by steepness so you can see what is coming.
