X-tracker

With X-Tracker, you can see how your training progresses.

Enter the weight and repetitions after each set. Then you'll immediately see if you're improving: as a graph for each exercise, sorted by training day in the calendar, or in a heatmap showing which muscle groups you've recently trained.

Create your training days from over 200 pre-made exercises. You can add your own exercises at any time. If you forget to log a set, the app automatically marks the entry so nothing gets lost. A timer runs alongside, measuring your rest between sets, visible in a small floating indicator that continues to follow you even if you briefly leave the app.

In addition, you can track your body weight and BMI, export your training data as a CSV or PDF, and share your training days with others if you wish.
