It combines essential gym calculators—RM, RPE, Plate, and Body Fat—in one lightweight app.

Estimate your one-rep max with three popular formulas: O’Conner, Epley, and Brzycki. Choose the one that fits your training style and goal.

- RPE Calculator
See the relationship between RPE and reps at a glance.
Switch between RPE-based and rep-based views to plan your training load precisely.

Plate Calculator
Instantly find the plate combination needed for your target weight. No more mental math between sets.

- Body Fat Calculator
Estimate your body fat percentage using the U.S. Navy method—just measure a few body parts. No smart scale required.

No clutter, no unnecessary features—just practical tools that help you train smarter every day.
