Your workout data is yours. You created every rep. You earned every PR. You shouldn't need a subscription to see it.

Somewhere along the way, fitness apps decided that analytics, templates, and progress tracking were premium features. Things to be unlocked. For $5 a month.

We think that's wrong. So we built the alternative.

Your last session's weight and reps appear on every set, automatically. No guessing. No wasted sets.
