Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The #1 PR tracker & 1RM calculator for powerlifters, CrossFitters, and serious lifters. Epley, Brzycki, RPE-adjusted. Track bench, squat, deadlift PRs. Own your strength
Your lifts deserve more than a notes app.
1Rep is the PR tracker built for lifters who treat every session like it matters — because it does. Log a PR in seconds. Watch your strength compound week over week. Hit new milestones. And when you PR, share it like it counts.

YOUR STRENGTH, FINALLY MEASURED
Most apps guess your 1RM with one formula. 1Rep uses seven — Epley, Brzycki, Lander, Lombardi, Mayhew, O'Conner, Wathan — and shows you how confident each estimate is with R² scores. No other PR tracker gives you this.
Run the math forward: enter your working set, get your true 1RM.
Run it backward: enter your goal 1RM, get your training weights for every rep range.

WHERE DO YOU STAND?
1Rep rates your lifts against real strength standards, scaled to your bodyweight. Are you Novice, Intermediate, Advanced, or Elite? You'll know by your next session.
See your percentile. Know your next target. Stop guessing.
