Hydration Smart

Hydration Smart is the smartest hydration tracking app for Garmin watches — built to keep you properly hydrated throughout the day with minimal effort. Logging water takes just 2–3 taps: open the app, select your cup size, and tap the + button. That's it. The app handles everything else automatically. Unlike basic water trackers, Hydration Smart uses an intelligent algorithm that automatically calculates the optimal times to remind you to drink water. It adapts in real time based on multiple personal factors: your wake-up time, physical activity level, time of day, and how much water you've already consumed. The result is a personalized hydration schedule that fits your actual day — not a generic fixed reminder every hour. Track in liters or ounces, with cup sizes you define yourself. Whether it's your 8 oz coffee mug or your 0.75 L gym bottle, log exactly what you actually drink. Works completely offline — no phone, no internet, no setup required. Everything runs directly on your watch. Key Features - Liters or Ounces — Choose your preferred unit. Every amount, your daily target, and your entire history are shown in the unit you pick. Switch anytime — your recorded data stays intact and is simply displayed differently. - Custom Cup Sizes — Set up to 4 cup sizes to match what you actually drink from: your mug, your glass, your water bottle. Hide the ones you don't use and keep the screen down to just the sizes you need. - US-Ready Defaults — Ounce mode comes preset with a 64 oz daily target (the classic 8×8 rule) and 8, 12, 16, and 24 oz cups. No conversion math required. - Smart Notifications — Intelligent reminders sent at the right time, automatically calculated in the background. More frequent around midday, adjusted after physical activity, and always based on how much you still need to drink to reach your daily goal. - Minimal Effort — Log water in 2–3 taps. No menus, no typing, no fuss. - Wake-Aware Scheduling — Detects when you wake up and starts your hydration schedule from that moment. No notifications during sleep or before 7:00 AM. - Daily Target Tracking — Set your personal daily water goal in liters or ounces. The app tracks your progress and stops reminders once you've reached your target. - Instant Updates — Change a cup size or your daily goal in Garmin Connect and your watch updates right away — no need to close and reopen the app. The notification schedule recalculates immediately too. - Nothing Gets Lost — Changed a cup size after logging from it? Those amounts still count toward your daily total and stay visible in a read-only list, so you always see exactly what you drank. - Full History — View your hydration history by day, week, month, and year. Track your long-term habits with beautiful progress bars. - Do Not Disturb Aware — Respects your watch's DND mode.

V 1.0.3 Choose your unit — liters or ounces Set your preferred unit in the app settings. All amounts, your daily target, and your entire history are shown in the unit you pick. Your recorded data stays intact when you switch — it's simply displayed differently. Customize your cup sizes The four cup sizes are no longer fixed. Set them to whatever you actually drink from — your mug, your glass, your water bottle. Set a cup to 0 to hide that row entirely if you only use two or three sizes. Separate settings for each unit Liters and ounces each have their own settings group, so the numbers you see are always in the unit you selected. Ounce users get sensible US defaults out of the box: a 64 oz daily target (the classic 8x8 rule) with 8, 12, 16, and 24 oz cups. Instant updates Change a cup size in Garmin Connect and the watch updates right away — no need to close and reopen the app. Nothing gets lost If you drank from a cup size you later changed, those amounts still count toward your daily total and now appear in a read-only list below the main table, so you can always see exactly what you logged.
