One tap per set
Last time does the typing.
Weight and reps from your last session are already there. Tap Done. Move on. The Gym Test: one-handed, sweaty, under three seconds to log a set.
Avg log: 2.4s
Faster than paper.
Log a set in one tap. Every set opens with what you did last time. No typing. No menus. Under three seconds.
Built by a lifterNow on the App Store
Built for lifters who already know their program.
How it works
Designed for the bench, not your desk.
The core workflow stays predictable: bring your program, log against last time, rest, and review later.
Bring your program
Paste from Notes. Done.
Paste your routine from anywhere and Unit reads exercises, sets, reps, and weights automatically. Or build from scratch in under two minutes.

What Unit is not
Not an AI coach.
Unit doesn't tell you what to lift. You bring the program; Unit makes logging instant.
Not a social platform.
No feed. No followers. No likes. Training is personal.
Not for beginners.
Unit assumes you know your way around a barbell. That's a feature, not a limitation.
Not subscription-locked.
Core logging is free. Your workout data is never held hostage.
From the maker
Trained for years with a paper notebook. Tried the gym apps. All of them slowed me down: too many menus, too much typing, screens designed for a desk, not a deadlift platform.
Built Unit instead. One tap per set. What you did last time is already there. Rest timer follows you to the Lock Screen. Everything stays on your phone. No social, no AI, no ceremony.
The app I wanted. If you know your program and you’re tired of fighting your tracker between sets, might be the one you wanted too.

Common questions
Unit is an iOS gym tracker for intermediate-to-advanced lifters who already know their program. It's local-first, ad-free, and built around one principle: log a set in under 3 seconds, one-handed, mid-workout.
Yes — completely free at launch. No ads, no account, no paywall on any logging feature. I may add a small Pro tier later for power-user extras; if I do, core logging stays free.
When you start an exercise, Unit shows what you logged last time: same weight, same reps. Tap Done to log it again, or adjust before you tap.
Yes. All your data is stored locally on your device. No internet connection needed, no account required.
During onboarding, choose 'Paste text' and paste your routine from Notes or WhatsApp. Unit reads exercise names, sets, reps, and weights automatically. You can also take a photo of your program or build from scratch.
Any program with a fixed split. PPL, Upper/Lower, Full Body, or custom splits. You define the exercises and days; Unit doesn't impose structure.
Your data lives on your iPhone. iCloud Backup covers it. Nothing depends on a Unit server. You'd lose the app; you wouldn't lose your history.
Unit is live on the App Store as “Unit — Gym Notebook”. Tap any download button on this page, or search the App Store directly. Free to download, no account needed.
