GymFactor is a workout logging app that builds your training program, remembers every set, rep, and weight from last time, and turns each gym session into progress you can see — fully offline, no account, no feed.
Free to use. GymFactor Pro unlocks plate scan and more.
- Today's session, already builtOpen GymFactor at the rack and the workout is waiting — exercises, sets, and last time's working weights filled in.
- Log a set in one tapWeight and reps come pre-filled from last session. Nudge them if you need to, tap once, and the set is saved.
- Rest is timed for youA guided countdown runs between sets, so you pick the bar back up on schedule instead of whenever you look up.
- Progress builds itselfEvery logged set feeds a strength score, per-exercise trend lines, weekly volume, and a training heatmap.
Local-first by design
Your workouts stay on your devices
Core logging works fully offline. If you use iCloud, your training history syncs privately through your own Apple ID with CloudKit — we never run a copy of your workout log on our servers. There is no account to create and no social feed.

What is GymFactor
A gym workout tracker built around one job: logging
Most workout tracker apps bury logging under feeds, streaks, and ads. GymFactor is the opposite. Open it at the rack and today's workout is already there, with your last working weights filled in. Tap to log each set, rest with the built-in timer, and leave.
- Barbell & dumbbell lifters
- New to the gym
- Any split, any schedule
- Home & garage gyms
- Apple Watch first

Is GymFactor a free workout logging app?
Yes. Logging workouts, building a training program, last-session memory, progress charts, widgets, and the Apple Watch app are all free. GymFactor Pro is an optional subscription that adds AI plate scan and future Pro features, sold through the App Store.
What's the best way to log a workout at the gym?
Open GymFactor at the rack and today's session is already there — each exercise shows the weight, reps, and sets you did last time. Tap to log each set as you go, rest with the built-in timer, and finish. Your workout log builds itself with no typing from scratch and no spreadsheets.
Does GymFactor build a workout program for me?
Yes. Answer about fourteen quick questions — goal, experience, days per week, available equipment — and GymFactor picks a training split (Upper/Lower, Push/Pull/Legs, Full Body, or its own choice) and builds the routine. You can swap, add, or remove any exercise afterwards.
How does GymFactor help with progressive overload?
Every exercise carries your last working set forward and suggests the next target, so you always know whether to add weight, add reps, or repeat. A strength score and per-exercise trend charts show whether your lifts are actually moving up over weeks and months.
Can I track workouts offline, with no account?
Yes. GymFactor works as a guest on your device with no sign-up. All logging, programs, last-session memory, and progress work fully offline — you can open it in a basement gym with no signal. Network is only used for optional features like AI plate scan, iCloud sync, and purchases.
Can I log sets from an Apple Watch?
Yes. Start a workout on Apple Watch, log every set from your wrist, and see live heart rate and active energy. When you end the session, GymFactor writes a strength-training workout to Apple Health automatically.
How is GymFactor different from other workout trackers?
There's no social feed, no ads, and no account. It's a focused gym logger: today's workout, last-session weights, a rest timer, and progress you can read. Your training history stays on your devices and syncs privately through your own iCloud account if you choose.
What does the AI plate scan do with my photos?
A photo you take of your plates or dumbbells is sent to a processing service to estimate the weight and is not stored in your workout database. You always confirm the weight before it is logged. See the Privacy Policy for details.
Is my Apple Health data safe?
Health access is optional and only reads what you allow — weight, height, date of birth, and sex, plus heart rate and energy on Apple Watch. It is never used for advertising and never sold.
Which devices does GymFactor support?
iPhone and Apple Watch, through the App Store, and Android phones, through Google Play.
