Hydration is a water diary for your Garmin watch. Log a drink with one tap or a button press, choose your drink sizes, set a daily goal and follow your progress against an animated water background. Made for selected fēnix 8 and fēnix 9 models, fēnix E, D2 Mach 2 Pro, Forerunner 570 (47 mm), Forerunner 965 and Forerunner 970, plus compatible variants listed by Garmin. Check Compatible Devices for your exact model. The core water diary works without a phone or a separate account. English is the default language; switch to Russian in Settings → Language / Язык. QUICK START • Add water: select a circle with a volume, then tap it in the center or press START. Change the selection with UP/DOWN, a horizontal swipe or a tap on a side size. The + circle creates a drink size without logging water. • Undo: after adding water, tap the pink X or press START within 3 seconds. The white ring shows the remaining time. Tap outside the X to keep the entry immediately. • Open the menu: tap the gear or hold UP/MENU. Short UP/DOWN presses change the drink size instead. BACK returns to the previous screen. • Set a goal: tap the target icon or open Settings → Daily goal. Enter 500–6000 ml on the keypad and save with the blue checkmark. With buttons, use UP/DOWN to select a key and START to activate it. • Edit today's total: tap the total at the top or open Menu → Edit daily total. Enter the full daily amount in ml. The first digit replaces the selected number; the red key deletes a digit and holding it clears the field. The blue checkmark saves. BACK asks before discarding changes. • History: use the bars icon or Menu → History. Week / Month or START switches views; UP/DOWN, arrows and horizontal swipes change periods. Weekday labels and monthly day circles are larger. Today has an outer outline in the month view: blue before reaching the goal, white afterwards. Tap a day to edit its total; MENU opens dates and the journal. Journal entries can be edited or deleted with confirmation. • Glance: add Hydration to your watch glance list to see today's water, goal, remaining amount and percentage. Open the glance to launch the app. MAKE IT YOURS • Keep up to 12 drink sizes from 10 to 2000 ml. Choose + on the home screen or Settings → Drink sizes → Add size. Enter a whole number and save with the checkmark. For a duplicate volume, choose the existing size or change the number. • In Settings → Drink sizes, select a size to edit its volume or delete it with confirmation. Logged water is kept. Remove all sizes and + remains on the home screen. Both screens share the list. • Set your daily goal, reminder hours, minimum interval and snooze. If the size list is empty, a new reminder prompts you to open the app without an add-water action. • Choose Fin the fish, Okti the octopus, Kora the seahorse or Klik the crab to appear when you reach your goal. Bubble adds rising bubbles; No pet keeps the screen clear. • Adjust vibration and enable Reduced Motion for static effects. • Daily water and goal percentage are available through Connect IQ Complications to watch faces that support these data sources. Support depends on the watch face. YOUR DIARY Free, with no ads or in-app purchases. Your watch diary is stored locally. Hydration has no server and does not sync water entries to Garmin Connect hydration tracking. Active watch history is limited to 90 days and 3072 entries. Update without uninstalling to keep your history and settings; uninstalling deletes local app data. See the privacy policy for data handling, deletion and public complication details. If you connect a compatible Hydration phone companion, the apps can exchange diary data through Garmin while both are open. This is optional and does not sync entries to Garmin Connect hydration tracking. You choose your own daily goal. Hydration is a personal water diary. Support: [email protected]

Custom drink sizes and updated analytics • Add up to 12 drink sizes using + on the home screen or Settings → Drink sizes. Enter any whole-number volume from 10 to 2000 ml on the keypad. • Edit sizes and delete unused ones with confirmation. You can remove them all: + stays on the home screen. Creating or deleting a size does not change your water diary. • Weekday labels and monthly day circles are larger. Today's blue outline in the month view now sits outside the circle, clear of the number; it remains white after the goal is reached. Update Hydration without uninstalling to keep your diary and settings. History is stored locally on your watch. Uninstalling deletes local data; cloud recovery is not available.
