AI Analysis

●●SolidCozySolve My Problem

Replaces Zwift's $20/mo FTP test with a free, open-source iOS app that just works.

Strengths
  • •Direct Bluetooth FTMS pairing means zero account setup or cloud dependency.
  • •Exports standard .FIT files compatible with TrainingPeaks, Strava, and Garmin.
  • •Open-source Swift codebase allows community verification of the ramp algorithm.
Weaknesses
  • •iOS-only with Android stuck in beta APK limits the immediate user base.
  • •Lacks structured workout libraries found in paid competitors like TrainerRoad.

Post Description

I built a free iOS app so cyclists can stop paying $20/mo just to retest their FTP. The ramp test itself is a 25-minute Bluetooth interaction with a known protocol. It shouldn't require rent. This app is opensource, free, no ads, no tracking nor third party integrations because I just wanted to have a fun side project and have no interest in monetization.

If you are a cyclist, I would kindly ask for feedback on the app especially on the ftp test protocol instructions, trainer-model compatibility, and bug reports
