What is the difference, really?

Free gives you the full loop — a personalized target, logging, three reminders spread across your day, Health Connect sync, and a week of history. That is a complete habit for many people.

Pro makes the reminders smart: they recompute after every drink so the next nudge reflects your actual pace, they wind down two hours before bed, and work mode keeps a meeting-heavy day from turning into a notification storm. You also get 30-day trends and a one-page PDF report for your next urology visit.

Billing

All purchases happen through Google Play, per its billing rules for digital subscriptions. The annual plan starts with a 7-day free trial; cancel anytime in the Play Store under Subscriptions. A lifetime unlock is available for people who would rather pay once.
