Frequently asked questions

SimuFit is a mobile-first strength-training app. Get a personal program from AI or a template, or build your own; log workouts fast at the gym; and follow your progress in clear reports.

Anyone aged 16 or over who trains at the gym or at home: beginners, people returning to training, and experienced lifters with their own program.

No. SimuFit is a progressive web app (PWA). Open it in your browser and, if you like, add it to your home screen – it then works like a normal app, offline too.

Any modern browser: iPhone and iPad (Safari), Android (Chrome) and computers. The workout screen is designed for a phone and one hand.

You answer questions about your goal, experience, schedule, equipment, injuries and health. The AI builds the program only from the curated exercise library, and rules check it before you see it.

Tap swap on the exercise and choose a similar, no-equipment, easier or harder option – for today only or for the whole program.

The workout screen works completely offline. Logs are saved on your device and sync when you are back online.

Workouts are saved on your device first and, when you are signed in, synced to your account. See the privacy policy for details.

Download all your data as JSON from settings. Deleting your account deactivates it immediately, and personal data is deleted within 30 days.

Only the profile needed to build your program is sent to the AI, without your name or email. Under the provider’s terms, data sent through its API is not used to train its models.

No. SimuFit gives general training and nutrition information and does not replace an assessment by a doctor or physiotherapist.

No AI program is generated during pregnancy. A gentle program is available, recommended only after your doctor or midwife has cleared you to exercise.

Enter the injury by body area and severity. Unsuitable exercises are left out or modified. Stop and seek help if you feel chest pain, dizziness or unusual shortness of breath.
