Baker's choice. Dense with flavour, light on filler.
Summary
A developer describes building a custom fitness tracking app called Obitrain to solve the problem of managing training data across multiple devices (Garmin, Polar, Withings, Apple Health) while also logging calisthenics and strength moves like front lever that mainstream apps don't support. The app aggregates data from connected devices into a weekly view and the creator is exploring AI insights integration. It's currently free and has been in personal use for over 4 years.
Key quotes
· 4 pulledI do calisthenics 3×/week plus Ironman 70.3 prep, which means my training lives across Garmin, Polar, Withings + FIT files and front-lever sessions that no mainstream app models.
So I built one that does both (and have been using for the past 4 years+): logs custom strength moves (front lever, FLAC, ¾ pull-ups), aggregates the connected devices (Polar, Garmin, Suunto, Withings, Apple Health) into one weekly view.
Currently trying to see if can integrate some AI insights to my training routines.
App is free for now as it does not cost me much (only servers for now), comment / use cases welcome: https://obitrain.com/
