About Indoor Space Program
Pedal and the rocket climbs; stop and it falls. You fly from the launch pad past Everest, the Moon and the Sun to the edge of the universe, at your own pace or in a workout: a ramp test sets your FTP, and endurance, tempo, sweet spot, threshold, over-unders, 30/30s, 4 × 4 and pyramid sessions hold the watts on the trainer (ERG) over FTMS. A mini mode is a small window with your watts and altitude to park next to a film or series. There is a leaderboard, things to unlock along the way, and a FIT export of each ride for Strava. Runs in Chrome or Edge on a computer with FTMS trainers or a Bluetooth power meter; no account and no ads. An iPhone/iPad version is planned. Made by Žiga Krajnc.
