Gym Tracker: the Pokémon game you play by lifting

▶ Watch the showreel in HD with sound (15 seconds)

A workout log where every set you save is an attack. Log weight × reps × sets as usual, and your Pokémon fights with them: wild Pokémon to catch, gym leaders to beat, a Pokédex to fill. Two full campaigns, FireRed's Kanto and Emerald's Hoenn, run entirely on your real training.

▶ Try it live: a new game in a phone-sized window

The try-it link starts a fresh game every time, from Professor Oak's welcome and your first Pokémon. On a computer it shows the game at phone size; on a phone it opens full screen. It keeps its own save, so it never touches a real one.

To use it for your own training, install the app from mateuszkrw-coder.github.io/gym-tracker-pokemon-game: it runs full screen and offline like an app, with no account and no server. Everything stays on your device.

How it works

• You train, the game follows. It is a normal gym log first: muscle groups, exercises, weight × reps × sets, a rest timer, notes per machine, history, charts and personal bests. The game never asks you to do anything but log your training.
• Every set is an attack. Start a workout and a wild Pokémon appears. Each set you save hits it, and it hits back. Weaken it, then throw a ball to catch it.
• Effort, not raw kilos. Damage and EXP scale with how close a set comes to your best on that exercise, so a 10 kg lateral raise at your limit hits as hard as a heavy leg press at yours.
• Two campaigns. Kanto has all 151 Pokémon, 8 gyms, the Elite Four and places like the Safari Zone, the Game Corner and Silph Co. After the Kanto Champion, the S.S. Tidal sails to Hoenn: the full Team Magma and Aqua story and all 202 Pokémon of the Emerald Pokédex.
• Trainer levels and cards. You level up too. Each level offers three cards (common, rare or epic) and you keep one: more damage, better catch rates, extra money, and more.
• Rest days are safe. Nothing is lost for a missed day, and streaks survive a rest day or two.

Install on iPhone

1. Open mateuszkrw-coder.github.io/gym-tracker-pokemon-game in Safari.
2. Tap the Share button (the square with an arrow).
3. Tap Add to Home Screen, then Add.
4. Launch it from the home screen icon. It runs full screen and works offline.

Your data

• Everything lives only on your phone (localStorage), tied to the installed app.
• If you delete the home screen icon, the data goes with it. Use OPTION → Export now and then to keep a backup file, and Import to restore it.
• The installed app and a Safari tab have separate storage. Log your workouts in the installed app.

Updating the app

1. Edit the files and commit to main. GitHub Pages publishes the site from the repository root.
2. Important: in sw.js, bump the version string (for example gym-tracker-v58 → gym-tracker-v59), or installed phones keep the old version.
3. Installed phones pick up the new version the next time the app is opened with internet. Close it fully and open it twice.
