Frequently asked questions
Do I have to pay to use Karven? No. You can log workouts and diet manually for free, forever. The subscription unlocks the AI Coach: automatic workout generation, personalized suggestions, and meal photo analysis.
How does the AI Coach build my workouts? It considers your goal, level, available days, and equipment, and generates complete plans that adjust as you progress.
Do I need gym equipment? No. You tell us what you have available (gym, home, dumbbells) and workouts are adapted accordingly.
How does diet tracking work? You log your meals and Karven automatically calculates calories and macros, suggesting adjustments when something is off target.
Can I cancel anytime? Yes, the subscription has no commitment period. Cancel anytime directly in your Apple ID or Google Play account settings.
Do I need my phone nearby to use the watch? Yes. The watch mirrors the session running on your phone, which remains the source of truth for your workout. Heart rate and calories are measured by the watch itself and shown in its summary at the end of the workout.

Common issues
- I can't sign in: check your connection and make sure you're using the same login method (email, Apple, or Google) as your original sign-up. If it persists, send us an email.
- My purchase didn't show up: try Profile → Restore Purchases first. If that doesn't fix it, send us your proof of purchase by email.
- The watch app isn't syncing: check that Bluetooth is on and your phone is nearby, then reopen the workout on both devices.
- A workout wasn't generated: check that your profile (goal, level, equipment) is complete in Profile and ask the AI Coach for a new workout again.
