About this app

Makes it quick and easy to get a full overview of all weights, reps and sets based off your 1RM when you’re following the 5/3/1 program.

- Save your current 1 RM for each of the four exercises

- View calculated weights for each step in the cycle

- Round the weight to match the plates you have available

This app is made for people who are familiar with the structure of the 5/3/1 program and who needs simple access to the calculated weights for each exercise.

Ratings and reviews

Great app! Workout timer, logs, graphs, reasonable interface. Things I'd love: - Would be nice to see if the last workout was a 5, 3 or 1 day without going into the log - Saving additional sets into the log would be nice, too. - Automatic sync with Google Drive would be so sweet - Option to make all the graphs use the same time frame, regardless of data points for that exercise - Show top set/date on each data point on graph when clicked - Custom plates sets per exercise (ex: 15lb bump/no iron)

The best program out there. Not to mention the best app! Very simple app with minimalist features just like the program

Why is there no calender or tracking like in IOS version? It should have that or there's no point in having the app. I wasted ten doars after switching to android but it isnt optimized
