Answers, straight up.

Is Weightoo really free to try?

Yes — new users get a 7-day free trial of Premium. After the trial you can pick a weekly, monthly, or yearly plan. Cancel anytime from your App Store or Google Play settings.

Do I have to count calories?

No. Weightoo is deliberately built for people who don't want to count calories. You focus on daily habits and weight logs; the app handles the rest.

Is the AI coach actually helpful?

The coach knows your profile, your recent weight logs, your habits, and your streak — so responses are tailored to you, not generic advice. Ask about plateaus, cravings, sleep, motivation, or anything you'd ask a real coach.
