About WattWorlds
PC app that turns a smart trainer into a game controller: ride WattWorlds' own world or open-world games you already own, so far Skyrim and GTA V, where the in-game terrain sets the resistance, your watts set the speed and your phone on the bars does the steering. A phone app changes settings mid-ride and can also link the trainer to the PC. Works with Bluetooth FTMS and ANT+ FE-C trainers. You need your own copy of each game; its files aren't changed. Free to ride, no subscription, with FIT/CSV export; workouts with ERG, Strava upload, multiplayer and more games are on a public roadmap that waitlist members vote on. Closed beta from 7 November 2026 for a group from the waitlist.
