HydraIQ

HydraIQ is a simple drink log with a daily water target based on your body weight and the local weather. Tap to log water, sports drinks, coffee or other drinks, and see how you are pacing through the day. • DAILY TARGET — About 35 ml per kg of body weight, raised on warm or hot days and when it is humid. Weather comes from Open-Meteo using your approximate location. Without location access you get the standard weight-based target. • PACE CHECK — HydraIQ compares what you have logged with what you would expect to have drunk by this time of day (6 am to 10 pm) and shows Well Hydrated, Drink Soon or Hydrate Now. • DRINK TYPES — Water, sports drinks, coffee and other drinks. Coffee counts at 70% of its volume. • APPLE WATCH — Log a drink from your wrist, and add a watch-face complication showing your hydration state and percent of today's target. • HISTORY — Your 7 most recent days of logged drinks, with daily totals. Delete any entry with a tap. FREE WITH ADS — HYDRAIQ PRO REMOVES THEM Every feature above is free. The free version shows a banner ad. HydraIQ Pro is an optional monthly or annual subscription that removes the ads. It does not unlock any other features. Payment is charged to your Apple ID on confirmation of purchase. Subscription auto-renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Settings > Apple ID > Subscriptions. Your drink log is stored on your device. HydraIQ gives general wellness information, not medical advice. If a medical condition affects how much you should drink, follow your doctor's guidance.

Tap what happened today. See tomorrow morning come into focus. Puffiness Forecast turns a few taps about your day into a plain-language outlook for how puffy tomorrow morning is likely to feel - shown the way a weather forecast is, not as a verdict. - Logging that ends in taps. A bowl of ramen is three taps: pick the dish, the amount, and how much broth you drank. No keyboard. Frequent items are one tap from Recents. - Words before numbers. Lower / Usual / Somewhat higher / Higher, with an honest range and a confidence level, plus at most three factors that explain it. - One tap in the morning. None / Slight / Strong / Very strong. No streaks, no failure states. - Tuned to you. After enough mornings, the app learns on-device which factors line up with your mornings. Nothing about that learning leaves this device. - Apple Watch and widgets. Raise your wrist for tomorrow's outlook, log the usual things in one tap, and offline entries arrive once you reconnect. - Stays on your device. No account. Health data is never used for advertising and never sold. Location is used only to fetch weather, and no precise location history is kept. --- This forecast is a reference estimate based on what you log. It does not measure body fluid or sodium and does not identify medical conditions. For sudden severe swelling, one-sided swelling, pain or redness, trouble breathing, or symptoms lasting several days, please contact a clinician rather than relying on the forecast.

Verdict

The call

The clearest difference is ads: むくみ予報 at none against HydraIQ's shown. HydraIQ's advantage is update cadence (weekly vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
