Finally a lifting log that gets out of the way
Clean, fast, and exactly what I needed for tracking strength workouts. Templates save me so much time — I just load my push day and go. The “copy last session” button is a small thing but I use it every set. Highly recommend if you lift regularly.
Exactly what a workout tracker should be
One of the best trackers I’ve used. Big exercise library, dead simple to log sets, and the templates save me real time. The interface is clean and user friendly. No forced signup either. It simply does what I need and nothing I don’t. Highly recommended!
Best App
Even if you’re new to this workout world like me this app will help you build your plan in a couple of minutes. Amazing work.
