Please, don’t kill my gains.

A workout tracker for people who already know what they’re lifting. It shows last time’s weight, you tap done, the rest timer starts. That’s the whole session.

Coming soon to the App StoreSee how it works

Free to start. No account or card needed to log your first workout.

Log a set in two taps.No typing. No menus. No thinking.

  • Last time, right there.

    Previous weight × reps and your note sit on every set row. Suggested weight is filled in before you touch anything.

    Free
  • Weight ruler, not a keyboard.

    Slide to the plate you loaded. Ticks match the equipment: 1.25 kg on a barbell, 2.5 kg on a machine, 0.5 kg on dumbbells.

    Free
  • Rest starts itself.

    Tap DONE, the timer runs, your phone counts you back in: 5, 4, 3, 2, 1, go. Haptics and sound, locked screen or not.

    Free
  • Timer on the lock screen and in the Dynamic Island.

    Never unlock to check rest.

    Free
  • Swap an exercise when the rack is taken.

    Substitutes are one tap away mid-session.

    Free
  • PRs get a moment.

    Beat your best and the app tells you, then gets out of the way.

    Free

Leave the phone in the locker.Log sets from your wrist. Rest buzzes on your wrist.

The Watch app runs the workout itself: heart rate, set logging, the rest timer. It syncs with the phone as you go, and if the two ever disagree, the sets you finished on the wrist are never thrown away.

  • Standalone session on watchOS 26

    Free
  • Heart rate saved to Apple Health

  • Rest timer haptic at zero

  • Same session, both screens, live

It knows when you got to the gym.And when you left.

Save your gym once. The walk there counts as warm-up, the session clock starts when you arrive, and if you leave mid-session the app asks whether you’re done instead of guessing. Location stays on your phone.

  • “You’re at Iron Works. Start Push day?” notification

    Free
  • Warm-up vs training time split on every session

  • Works with 1 gym or 5

Built by one lifter who was tired of three apps.

This started as a personal tool: one app to log the session, remember last time and show the trend, instead of a tracker, a timer and a spreadsheet. There is no social feed and no AI coach telling you to go harder. Support is answered by the person who wrote it.

Questions

Is it really free?

Yes. Logging, programs, previous values and notes, the Apple Watch app, the rest timer, gym locations, the 90-day e1RM chart, CSV export and Strong/Hevy import are free with no ads. Pro adds long-range analytics, the muscle-balance map and AI generation.

Do I need an account?

No. Your first workout runs without one; add an account later to sync.

Does it work without signal?

Yes. Every set is saved on the phone the instant you log it and syncs when you are back online. The Watch app works on its own in the gym basement.

Can I bring my Strong or Hevy history?

Yes. Export a CSV from Strong or Hevy and import it in Settings. Exercises we don’t recognise become custom exercises, so nothing is dropped.

What does Pro add, and can I lose free features?

Pro adds long-range analytics, the muscle-balance map and AI program and exercise generation. Can you lose free features? No, never. Nothing that is free today will move behind Pro.

Android?

No. iOS 26 and watchOS 26 only.

How do I delete my data?

One email to support and everything is gone, or delete your account in Settings inside the app. Either way it is deleted from our server, not just hidden.
