easy to use to track activity

Really enjoying this app. Looked for a while to increase change my workout from the starting strength/Texas method that is issued for 16 months and I stumbled you this one. I like how it automatically adjusts weight and reps based on previous workouts and combines focused exercises with compound exercises.

The app is great I recommend it to everyone.

Any program will take 6+ weeks to show results but I can definitely feel the light soreness from a hard workout, not that extreme soreness that last for 3-4 days. Really looking forward to seeing where I'll be in two months.

Perfect for powerlifting!

Been using this app for a month or so now and I'm loving it. Being able to easily see volume and rep PR's makes it easy to push yourself each training session. Yeah there's some bugs and slowness, but this is just the beginning and I know they'll get ironed out. Pun totally intended. ;)
