Every PR kept.

Coming soon to the App Store

Peak's lift detail screen for Back Squat: a current 1RM of 485 LB set very large, from 485 LB × 1 on June 27, 2026, then a View % of 1RM band and a history grouped by year, with red PR tags on 485, 475 and 455 LB and a red line reading Baseline set, 435 LB, Feb 8, 2025.
Peak's home screen: six lifts, each with its current 1RM set large in LB. Back Squat 485, Bench Press 270, Clean & Jerk 215, Deadlift 605, Front Squat 325 and Shoulder Press 175. Bench Press and Shoulder Press carry a red EST. qualifier, and Clean & Jerk's date, Feb 15, 2025, is red because it is more than a year old.

What it does

Peak shows your current one-rep max on every lift and keeps every PR with its date.
That’s it, focused and clean.

Peak share card: Back Squat 1RM, 485 LB, June 27, 2026

Share the PR

A clean card ready for your feed. Add a photo or video of your lift behind it if you want.

  • Actual or estimated. A single is a true 1RM. A triple or a five gets an Epley estimate, marked est.

  • Lifetime history. Every set, grouped by year. Your all-time best keeps its own line.

  • Set Baseline. Back after a break, set a new starting line, and your old PRs stay.

  • Film the lift. Attach a photo or video to any set.

  • Old maxes flagged. A current 1RM more than a year old shows its date in red.

  • Any lift. 60 barbell lifts built in, or name and add your own.

  • New PR, noticed. Beat your best and Peak marks it with a haptic tap.

  • Works offline. No signal in the gym? Log anyway. It syncs when you’re back online.

  • New phone, same lifts. Everything syncs through your iCloud, so a new iPhone gets it all back.

Questions

Is there a subscription?

No. The first 3 lifts are free, with every feature. A one-time purchase unlocks unlimited lifts.

How does Peak estimate a 1RM?

With the Epley formula, weight × (1 + reps ÷ 30), for sets of 2 to 10 reps.

Can I add my old PRs?

Yes. Log the set with its original date and it lands in the right year.

Where is my data stored?

On your iPhone and in your own private iCloud.

Does Peak track workouts?

No. It tracks your one-rep max on each lift and the sets behind it.

Is Peak a Strong or Hevy alternative?

Not a replacement. Peak tracks your maxes, not your workouts, so it works alongside Strong or Hevy.

Is there an Android or Apple Watch app?

Not yet. Peak is iPhone only for now. If there’s user interest, that could change.
