Hydro Dots
Read full descriptionHide full description
Hydro Dots is a water tracker that draws your day as a rising water level, one dot at a time. Tap once to log a cup, a mug, or a bottle. The water climbs. That is the whole idea. WHAT IT DOES • One tap to log — your usual sizes sit on the first screen. Custom amounts and drink types are one tap further. • Not every drink counts the same — coffee, tea, juice and the rest are converted by their hydration index, so what you log is what your body keeps. • A goal that follows your day — body weight, temperature, humidity, UV and activity shape the target. It settles once, the first time you open the app each day, so it never moves under you. • Reminders that know where you stand — each one carries how much you have had and the pace that would get you there. • History and recap — a week of bars, a month of dots, a streak counter, and the month's total turned into things you can picture: bottles, kettles, sugar you avoided. • Widgets — log from the home screen or the lock screen without opening the app. A month of dots fits on the large one. • Shortcuts and Siri — log a drink or ask what you have had today, hands free. Every action is available to build your own routines. • Apple Health — records can be written to Health, and removing a record takes it back out. PRO A one-time purchase. No subscription. • No ads • Every theme — seven palettes, from cream LCD to OLED black • iCloud sync — records and drinks across your devices PRIVACY What you drink stays on your device. Your records are not sent anywhere unless you turn on iCloud sync, and then they go to your own iCloud, not to us.

Verdict
The clearest difference is in-app purchases: Weight Manager at none against Hydro Dots's 4. Weight Manager also leads on iOS requirement (17.6 vs 26.0). Hydro Dots's advantage is update cadence (daily vs fortnightly). On price, ads and device support there is nothing between them.
