Singlet is the running log you need to keep track of your progress as a runner. That's it, that's what you need to know.

Apple Watches, Garmins, Polars, even if you only use your phone. Every single source of data works and it's read by Singlet. Any device that writes workout data to HealthKit works. Singlet will then display all the relevant data you need to know so you become a better runner.

Press kit.

Notable features:

Heads up for developers, alongside this app I am maintaining HKCombine, an open source Combine-based wrapper for common HealthKit operations that I use in this application.


Singlet does not track you in any way. In fact it doesn't use any third party libraries. Everything stays on your device.
