The app is the weakest link. It’s available on Google Play and Apple App Store but looks like it was designed in 2016. Syncing is unreliable—sometimes you need to disconnect and reconnect Bluetooth. Data export is clunky (only CSV), and there are frequent ads urging you to buy a more expensive Qstart model. No integration with Google Fit, Apple Health, or Strava.
Imagine NPCs that don't just repeat lines, but react to your specific achievements in real-time.
