Field notes
The page lists trainer modes, interval controls, workout charts, FTP testing, and a guard against a “spiral of death.” Riders can import GPX routes, with the trainer responding to gradients, or use a workout builder that accepts intervals.icu text and common workout-file formats. A pre-release badge and an Apple Silicon requirement set useful expectations; the project also links its code on GitHub.
