Hydropal

Stay hydrated without the guesswork. Hydropal is your personal hydration assistant that adapts to your lifestyle and keeps you on track. If you're not tracking your hydration, it's impossible to know if you're drinking enough. And most tracking apps aren't much better: they make you guess how much you've had and give you the same goal whether you hit the gym, had a few beers, or spent the day in the sun. Hydropal is different. Instead of making you estimate, it does all the thinking for you. It calculates your intake based on your real containers, adjusts your goal based on what you do every day, and sends you timely reminders only when you're falling behind. It's hydration tracking that finally makes sense. KEY FEATURES β’ Adaptive daily goals β’ Smart reminders β’ Container-based tracking β’ Huge catalog of presets β’ Custom drinks and containers β’ Personal units β’ Motivating streaks β’ Apple Health integration β’ Powerful even without Pro ADAPTIVE DAILY GOALS Your hydration needs aren't the same every day, so your goal shouldn't be either. Hydropal calculates a personalized target based on your body, and adjusts it throughout the day based on what you're actually doing. β’ Activity tracking: Your goal increases based on calories burned, pulled directly from Apple Health, working seamlessly with your iPhone and Apple Watch. β’ Alcohol tracking: A hangover is mostly dehydration. Alcohol draws water out of your body, and it's easy to forget to replenish it. Hydropal adjusts your daily goal whenever you drink alcohol, so you can thank yourself tomorrow! β’ Caffeine tracking: Caffeine can displace water in your body. Hydropal estimates your caffeine tolerance and calculates how much more water you need to balance it out. β’ Climate and time outdoors: Hydropal adjusts your goal based on temperature and how much time you spend outside. SMART REMINDERS Most hydration apps remind you on a fixed schedule, whether you need it or not. Hydropal is smarter: it only reminds you when you're actually falling behind. β’ Daily hydration curve: Hydropal maps out your ideal hydration throughout the day based on your sleep schedule. This ensures you're drinking steadily and won't have too much water in your system before bed. β’ Fully customizable: Choose how many and which types of reminders you want to receive. Hydropal adapts to how much (or how little) you want to be reminded. CONTAINER-BASED TRACKING Stop estimating how much you drank. Hydropal keeps track of your real-world containers, including mugs, glasses and your personal bottle. Match the liquid level on screen to what's in your container, and Hydropal calculates exactly how much you drank based on the shape and volume. Hydropal remembers each containerβs fill level throughout the day, so you can switch between them freely without losing track. With over 40+ containers and 80+ drinks, plus the ability to create your own, you'll always find your glass half-full. HYDROPAL PRO Hydropal is powerful out of the box: track unlimited drinks and containers, connect to Apple Health for adaptive goals, receive smart reminders, and even edit yesterday's entries in case you forgot to log something. Hydropal Pro unlocks deeper customization and total control: β’ Create your own custom drinks and containers. β’ Track casual drinks with personal units like sips and gulps (perfect for drinking from the tap). β’ Sync water, caffeine, and alcohol data with Apple Health for a complete picture of your wellness.
