One Gym Man
Free on iOS & Android

Real reps.
Real damage.

One Gym Man is a workout tracker with a monster problem. Every session you log — bench, squats, deadlifts, a run — powers up your hero. Then you take that strength into battle against 30 monsters across 10 threat tiers, and the only way past the next tier is to actually get stronger.

Power = Strength × (1 + Morale) × Agility, for both sides. Green means easy win, yellow a close fight, red very hard — exactly how the app colours the list.

How it works

Train. Power up. Pick a fight.

A serious session log on the way in, a turn-based monster brawl on the way out.

1

Log the session

Weight, reps and sets for the classic lifts, distance and time for runs. Presets fill a whole session in one tap, and Repeat reloads your last one.

The workout log: a session with Bench Press 150 lbs for 5 by 3, Push-ups 24 by 3, and a 2.5 mile run, above a Complete Session button
2

Stats grow from real training

Lifts feed Strength, cardio feeds Agility, and a training streak raises Morale — a damage multiplier for showing up day after day.

The progress screen: 21 workouts in 21 days, +367 Strength gained, a 9-day streak, and bar charts of Strength and Agility growth
3

Take the fight

Turn-based combat where your numbers do the talking: Heavy Strike, Quick Strike, or Defend and counter. Win, and it goes on the trophy wall.

Mid-battle against Deep Sea Tyrant: your health bar at 391, the monster at 114, a battle log, and Heavy Strike, Quick Strike and Defend buttons
The screens

Ten tiers of trouble, one of you.

The monster ladder runs from Wolf to God-tier. Every card shows your live odds before you commit.

The Select Enemy screen: your power level, this week's boss Void Juggernaut rated Hard, tiers 1 to 4 cleared 3 of 3, and Tier 6 monsters rated Hard

The threat ladder

30 monsters in 10 tiers, colour-coded by your real chance of winning. Tier names escalate from Wolf to God.

The Add Exercise screen: required bodyweight basics marked with stars — push-ups, sit-ups, squats — and secondary barbell lifts including bench press and deadlift

An honest exercise list

The bodyweight basics are required, the barbell lifts are where the numbers grow. Skipping fundamentals costs you stats.

The Achievements screen: 14 total victories, with defeated monsters like Flashy Slash and Pollution Monster, each showing turns taken and HP remaining

The trophy wall

Every kill is recorded — turns taken, HP left, date — and any of them can be shared straight from the app.

Why it sticks

Built to make you show up.

Every mechanic points the same way: back into the gym.

Weekly boss

One boss a week, identical for every player in the world, scaled to hurt. Beat it before the reset.

Combat you steer

Heavy Strike for 1.5×, Quick Strike to chain turns, Defend to block and counter. Your stats set the ceiling; you play the hand.

Streaks become damage

Every consecutive training day raises Morale, and Morale multiplies every hit. Consistency is literally a buff.

Repeat & presets

Reload your last session in one tap, or start from a ready-made split. Logging takes seconds, not minutes.

Progress you can see

Charts of Strength and Agility over time, total workouts, streaks and your full session history.

Yours to keep

No account, works offline, and one tap exports your whole save as a backup code you can import on a new phone.

Questions

The short answers.

Is it free?

Yes — every feature is free. The app is supported by ads: a small banner, plus an occasional interstitial that only starts appearing once you've logged a good number of workouts. No subscriptions, no paywalls, no in-app purchases.

Do I need an account?

No sign-up, no login. Your character, workouts and victories live on your device — and you can export the whole save as a backup code and import it on a new phone.

What can I log?

The classic barbell lifts — bench press, squat, deadlift, overhead press, barbell row — plus push-ups, sit-ups and running, each with weight, reps, sets, distance and time. Presets fill a whole session in one tap.

How do battles actually work?

Strength exercises build Strength, cardio builds Agility, streaks raise Morale — and damage is Strength × (1 + Morale). Fights are turn-based with three moves: Heavy Strike, Quick Strike, Defend. There's no gear, no gacha, no shortcut: higher tiers fall to heavier lifts and faster miles.

What's the weekly boss?

Every week the app generates one boss — the same for every player in the world — scaled to be a genuine challenge. Beat it before the reset and it goes on your trophy wall with the rest.

Can I cheat by logging fake workouts?

Sure — and you'd be lying to a fictional monster ladder only you can see. There's no leaderboard on purpose. The only opponent that matters is last month's you.

The monsters aren't getting stronger.
You are.

Free. No account. Tier 1 is a wet paper bag with a face — see how far you get.
