Every calculator works right now, free. Try Muscle Potential and decide later.Questions
Is the free plan actually useful?
Yes. Every calculator — including Muscle Potential — is free with no account. A free account adds unlimited check-ins, charts, saved results and three Analyst questions a month. Pro is for people who want the analysis done for them.
How does the free trial work?
Start Pro and you get 7 days free. Cancel before the trial ends from Account → Settings and you will not be charged. One trial per account.
Can I cancel any time?
Yes, in two clicks through the secure Stripe billing portal. You keep Pro until the end of the period you paid for.
Is MuscleFlare Pro the same as MuscleYou Premium?
No. They are separate products with separate subscriptions. MuscleFlare focuses on body composition, potential and progress analysis; a subscription to one does not include the other.
What happens to my data if I cancel?
Nothing is deleted. You keep all your check-ins and results on the free plan, and Pro analysis returns if you resubscribe.
