What's the best Android app for tracking daily water intake and staying hydrated?

Hydro Buddy is a streamlined hydration tracker designed to simplify the process of monitoring daily water intake. The app excels by allowing users to set personalized daily fluid goals, which can be adjusted for factors like activity level or climate. A key feature is its visual logging system, where users tap to add common container sizes—like a glass, bottle, or mug—making quick entries intuitive. The customizable reminder system is particularly useful for individuals with busy schedules who might otherwise forget to drink water regularly. Users can schedule notifications at intervals that suit their routine, which is helpful for office workers or students needing consistent prompts throughout the day. However, the app relies on manual entry, which some reviews indicate can become a minor chore for those who prefer automatic tracking via connected smart bottles. The interface is clean and the hydration history charts provide a clear overview for spotting patterns, useful for someone preparing for a doctor's visit or trying to correlate hydration with energy levels. While the free version is functional, a one-time upgrade unlocks more detailed statistics and the ability to track other beverages like tea or coffee, which is a consideration for users wanting a comprehensive fluid log.
