AtomFit - Gym Workout Tracker

AtomFit is a gym log for people who lift. It opens on your training, it works in a basement with no signal, and it asks you for nothing — no account, no ads, no subscription.

Everything you make is yours and uncapped: routines, exercises, history, measurements. There is no free tier that runs out.

The logging screen
• A numeric keypad, never a scroll wheel
• Prefilled with what you lifted last time, not what the template hoped for
• A rest timer that runs with the screen off, and survives the app being killed
• Rest per set, shorter rest after warm-ups, superset rest that waits for the block
• A set timer for planks and carries; intervals for EMOM, Tabata, AMRAP and circuits
• Warm-up sets from your working weight, and plate maths for your bar
• Machine taken? Swap in an alternative for the same muscle with your equipment
• Drag to reorder, undo anything, log left and right sides separately
• Seven ways to track a movement: weight and reps, assisted bodyweight, duration

962 exercises, and room for yours
• Search by the name you use — aliases are built in
• Filter by muscle, equipment or category; favourites and recents first
• Grip, angle and attachment as variants, so close-grip bench stays in bench press's history
• Custom exercises, with a photo of the machine you took yourself
• Per-exercise weight unit, machine base weight, bands logged by name

Routines and programs
• Routines, folders, supersets and circuits, in any number
• Nine templates to start from, including StrongLifts 5x5, nSuns 5/3/1 LP, GZCLP and PHUL
• Multi-week programs with a schedule, deload weeks, and a cursor that knows what is next
• Progression rules that raise the weight for you and back it off when you stall

History and records
• Calendar, session detail, and a full edit of a past session, records recomputed
• Records per rep count, heaviest weight, best set, best volume, estimated 1RM
• Strike out a record you know is wrong — a typo, another gym's machine

Progress
• Body weight, body fat and limb measurements, with BMI, lean mass and symmetry
• Progress photos side by side, and a calorie estimate for every session
• Weekly sets per muscle group against a target you set
• Per-exercise charts, muscle recovery, monthly and yearly reports

The rest of your phone
• Home-screen and lock-screen widgets, and a tile that starts a workout
• Wear OS: start a session, tick sets off, read heart rate from your wrist
• Health Connect, and Bluetooth heart-rate straps
• Reminders on the days you train, and the log behind your device's lock
• Dark and AMOLED-black themes, Material You colour, 22 languages

Your data can leave whenever you want it to
• Automatic rolling backups, with a restore preview and an integrity check
• Import your history from another workout app's CSV export
• Full-fidelity JSON export, and a session or a month as PDF, CSV or TCX
• Share a session as an image, or a routine or program as a file or a QR code

Sync, if you want it
Your training on your other devices, through your own Google Drive — the hidden space only this app can read. There is no AtomFit server, and never will be.

AtomFit Pro — one payment, not a subscription
Everything above is free. Pro unlocks nine things: Google Drive sync, per-exercise charts, goals, weekly muscle targets, muscle recovery, monthly and yearly reports, the full rep-max table out to thirty reps, programs and progression, and gym profiles.
One purchase, held by your Google Play account across devices and reinstalls.

What this app will never do
No ads. No subscription. No account. No cap on anything you create. No feature that needs a network. And nothing that ships free is ever moved behind the price.

For strength training, bodybuilding, powerlifting, calisthenics, kettlebells and machines.
