Questions people ask before buying

Why do I check out on the web?

You buy CarbRate Pro here on carbrate.com and it unlocks in the app. Managing your own billing on the web is what lets us offer the one-time Race Pass and lets you update, pause, or cancel any time from your account.

What exactly is the Race Pass?

Full Pro for one race: an 18-week window that starts when you buy and ends 7 days after race day — long enough for your report card and your “what's next.” It is one flat payment that expires on its own, so there is nothing to remember to cancel.

Is there a free trial or a guarantee?

No trial and no money-back guarantee — because the free tier already lets you try the real thing: a working partial plan, the full course library, and your first guided sweat test. Taste it free, then upgrade when it has earned it.

Can I cancel or pause?

Any time, from your account. If you step down to the free tier your record stays with you — sweat history, plans, and report cards are yours to keep, not the subscription's.

I'm outside the US — can I still use it?

Yes. Buy CarbRate Pro here on the web from anywhere, then sign in with the same email in the app and your plan unlocks.
