A free personal trainer app — free for life
ChallenGYM gives personal trainers and online coaches a complete coaching app without a subscription, without ads and without a credit card. Not a trial and not a limited free tier.


What “free for life” means
Every feature in the app today is free and stays free: client management, workout, cardio and nutrition plans, health questionnaires, check-ins, the plan library and the coach community. If optional paid extras are ever added, they will be clearly marked and will never take away what you already use for free.
- No subscription and no per-client fees
- No ads and no selling of data
- No credit card and no trial that runs out
- Free for your clients too
What you get
A 102-exercise library, 53 cardio workouts, 121 foods and 44 meals, eight-plus templates for each kind of plan, and 88 plans recommended by the ChallenGYM coaching team — in 32 languages, on iPhone and Android.
Why we built it free
Most coaching software charges per month and per client, which hits new and independent coaches hardest. We want every coach to have professional tools from the first client, and we grow by coaches recommending ChallenGYM to each other.
A community, not just an app
Coaches share plans to the library, rate the ones they used, publish exercises and ideas that three other coaches peer-review, and discuss what works. The best of it is available to everyone.
