Gym Log: Lift & PR Tracker

Track every set, beat your old numbers, and never lose your place between sets. Gym Log is a complete strength-training tracker: rest timer, workout builder, 1RM graphs, body measurements, and an Apple Watch app.

No account. No sign-up. No email. No ads. Open it and start lifting.

BUILT FOR HOW YOU ACTUALLY TRAIN

• Smart Rest Timer — auto-starts after every set, runs in a Live Activity on your Lock Screen and Dynamic Island, so you're not staring at the app between sets.
• Home Screen Widget — see this week's workout count and your best lift without opening the app.
• Workout Builder — build custom routines and drag-to-reorder exercises until it matches your split exactly.
• RPE & Warm-Up Calculator — log rate of perceived exertion per set and let Gym Log auto-generate your warm-up ramp to any working weight.
• Plate Calculator — instant per-side plate math for every barbell lift.
• 1-Rep-Max & Progress Graphs — every logged set feeds an estimated 1RM chart per exercise, so you can see the trend line, not just the number.
• Personal Records, Automatically — Gym Log flags every new PR the moment you log it and builds your all-time PR board for you.
• Body Log — track weight, body fat %, and body measurements (chest, waist, hips, arms, thighs) alongside progress photos, all in one timeline.
• Apple Health Sync — completed workouts sync straight to Apple Health.
• Apple Watch App — start workouts, log sets, and run your rest timer straight from your wrist.
• Share Your Wins — every finished workout and every new PR generates a bold, branded share card, ready for your Instagram Story in one tap.

BUILT BY ONE PERSON

I built Gym Log for myself, in a year when AI finally made something like this achievable alone — then kept building whatever people asked for. No team, no investors, and no roadmap written by anyone but the people using it. And no subscription: most gym apps put your own training data behind a monthly fee — your 1-rep-max trend, your custom rest timers, your own history. Gym Log doesn't work that way.

DESIGNED, NOT DEFAULTED

Gym Log doesn't look like a spreadsheet. Bold type, riveted steel-plate cards, a chalk-and-iron palette built to feel like the gym floor, not a productivity app.

Five starter routines (Chest Day, Back Day, Leg Day, Push Day, Pull Day) are built in so you can start your first workout in under 30 seconds — or build your own from scratch.
