I built Suzfit for my fiancée. She was tired of gym apps that bury a set log under programs, paywalls and feeds. She just wanted to track her workouts. This is that app, shared free with anyone who wants the same.

During the workout

It remembers what you lifted.

Last session's weight and reps sit beside every set, so you never scroll back to check. A gentle suggestion for each exercise, based on your progression rule. Type a weight once and it fills the rest.

  • Previous session in every row
  • Double progression, linear, or RPE
  • Add, remove or swap exercises mid-session

Rest that follows you.

The timer starts the moment you check off a set. Lock your phone, change the song, get water. You'll get a quiet alert when it's time to lift again.

  • Per-exercise rest times
  • Skip or add 30 seconds in one tap
  • Works with the screen off

The good part

PRs, caught live.

Lift heavier than ever, or more reps at your best weight, and Suzfit notices the moment you check the set. It turns gold, your phone buzzes, and the record stays with you.

  • Weight PRs and rep PRs
  • PR days marked on your activity heatmap
  • Every record listed in the session summary

Questions, answered.

Why was Suzfit made?

I built it for my fiancée. She was tired of bloated gym apps and just wanted a simple way to log her workouts. It grew from there, and I share it free with anyone who wants the same.

Is Suzfit free?

Yes, all of it: unlimited saved workouts, the full exercise library, weight suggestions, analytics and iCloud sync. I don't run ads, sell subscriptions, or lock anything behind a purchase.

Do I need an account?

No. Suzfit works the moment you open it. Your data lives on your iPhone and, if iCloud is enabled, in your own private iCloud account.

How do weight suggestions work?

Suzfit shows what you lifted for each set last time and applies your progression rule to suggest the next weight. Double progression adds weight once every set hits the top of the rep range; linear adds weight every session you hit the minimum; RPE adjusts to how hard the last session felt. Set it per workout or override per exercise.

Can I add HIIT to a strength workout?

Yes. Add finishers like mountain climbers or box jumps to the end of any strength plan with their own sets and rep ranges.

Does the rest timer work when my phone is locked?

Yes. It schedules a local notification, so you get an alert when rest ends even if the screen is off or you are in another app. That is the only reason Suzfit asks for notification permission.

Where is my data stored?

On your device and in your own private iCloud database. I run no servers and can't see your workouts. Details in the privacy policy.

Does Suzfit support kilograms?

Yes. Pick pounds or kilograms in Settings and every weight in the app follows, including your history.

Your gym. Your rules.

Free on the App Store. Nothing to unlock.
