Workout tracker FAQ
Good to know
What is Gym Commitment?
A training log. Start a session at the gym, log your sets with last time's numbers in front of you, finish when you are done. Over time it shows every lift climbing, which body parts you train, and which you skip.
Is it free?
Yes. Logging, plans, photos and the weekly goal are free, with no time limit. Pro opens your full history and unlimited plans of your own. You can pay for it monthly or yearly, or once for lifetime access. Everything you log stays yours either way.
Does it work on my Apple Watch?
Yes. Tick sets, watch the rest countdown, skip or adjust rest, move between exercises and add a set, all from your wrist. Your phone keeps the log, and the watch mirrors the session.
What is With your AI?
Connect your own ChatGPT, Claude or Gemini, tell it what you want to train, and it sends a finished plan straight to your phone. Some assistants need a paid plan or are not available in every country. Connecting is free, and we never see your chat or your photos.
Where is my data, and can I get it out?
On your phone. There is no account. Only what you choose to share with your AI leaves it, and the privacy policy says what we keep and for how long. You can export every session and set as a CSV file any time, with or without Pro. With Pro it backs up to your own iCloud or Google Drive, and we cannot see it there either.
Do I need a workout plan?
No. Follow one of the ready-made plans, build your own, or go freestyle and pick each day. Switch any time. Our guide to the best workout split helps you pick one for your week.
Is Gym Commitment on Android?
Yes. It is free on Android from Google Play and on iPhone from the App Store. The watch app is Apple Watch only.
Is there a printable workout log?
Yes. Our free workout log template prints on A4 or US Letter. When you want to skip the paper, the app fills in last time's numbers for you.
