(June 2026)"]]>After attempting a charity push up challenge in Feb I wanted to contiune with a similar app to track reps, so I build paayn (push ups are all you need).

It's deliberately minimalistic PWA that uses you mobile's sensors (camera, using lux levels and/or acclerometer) to count reps.

I included squats and sit ups later to round it out but it kinda made the name bad :)
