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.
