I was unsatisfied with my indoor training app. I don’t need all the paid features, the social side, the avatars. I just want to ride my session.
So I built my own and cut it to the essentials, with a slicker design, so I can actually enjoy the ride and focus on what matters most.

What it does
- Pairs over Bluetooth, from the browser. Smart trainer (FTMS), heart-rate strap, optional cadence sensor. Nothing to install.
- Structured workouts in ERG. The trainer holds the target watts for every step. Nudge targets ±10 W, or drop ERG for a step and ride it on feel. It releases resistance if your cadence collapses, so you never grind to a halt.
- Bring your coach’s sessions. Import any Zwift
.zwofile; coach notes show up during the step. - Switchable worlds. Three looks, switchable mid-ride: Default Valley, Cosmic Circuit, and Night Draft (above). Worlds are data-only packs, so anyone can make one.
- Never lose a ride. Recording is saved every 5 seconds and recovered after a crash.
- Post anywhere. A
.FITwith laps and HRV for Intervals.icu, Strava, Garmin Connect or TrainingPeaks. Strava gets a ready-made caption.
