Read full descriptionHide full description
Track every glass and build a daily hydration habit. HydraIQ adapts your daily goal to your weight and activity, sends gentle reminders, and visualises your streak. Most hydration apps just tally glasses. HydraIQ predicts when your body is heading toward dehydration and nudges you before thirst kicks in. Powered by live weather, your Apple Watch heart-rate signals, and your daily patterns. • SMART DAILY TARGET — Recalculated live from your weight, temperature, humidity and activity. No static 2-litre rule. • PREDICTIVE ALERTS — HydraIQ spots the gap between when you drank last and what your body needs, and nudges you with a friendly notification a few minutes BEFORE you'd feel thirsty. • APPLE WATCH COMPLICATION — Watch face complication with your live hydration state (Well Hydrated / Drink Soon / Hydrate Now) and percent of daily target. Log a drink straight from your wrist. • CLEAN DAILY DASHBOARD — At a glance: your target, what's been logged, and how you're trending through the day. • WEATHER-AWARE GOALS — Hot day? Humid? HydraIQ raises your target automatically so you don't fall behind. • DRINK TYPES THAT MATTER — Water, sports drinks, and coffee are tracked separately. Coffee counts at 70% hydration because caffeine is mildly diuretic. • FULL HISTORY — See your hydration trend over days, weeks and months. HYDRAIQ PRO HydraIQ Pro unlocks the predictive brain: • Predictive hydration alerts that learn your habits • Apple Watch complication on all watch faces • Weather-aware dynamic goals • Unlimited history and trends • Skin-type aware recommendations Subscribe: Monthly £1.99 or Annual £14.99 (best value — saves over 37%).

More than water Log coffee, tea, juice, or a glass of wine too. Sproutly weights each drink so your total reflects what actually hydrates you.
