H2OK: Water Tracker & Reminder

H2OK is a simple, friendly water tracker. Tap once to log a glass, watch it fill, and get on with your day. LOG IN ONE TAP Pick a cup, slide to the amount, done. Glass, bottle, flask: set up the cups you actually use. A DROP THAT CHEERS YOU ON The little drop wakes up as you drink, smiles at a quarter, cheers past halfway and says "H2OK!" when you're done for the day. REMINDERS THAT KNOW WHEN TO STAY QUIET Reminders only while you're awake. If you just had a drink, the next one waits. Once you reach your goal, they stop. Log a glass straight from the notification without opening the app. A GOAL THAT FITS YOU A daily goal suggested from your weight and how active you are. Hot day? Tap the sun and add 500 ml until you turn it off. HISTORY AND STREAKS Your week as bars, your month as drops, your year as a heatmap, and every liter since your first sip. A day counts once you reach 80% of your goal. Tap any day to see it or add something you forgot. PRIVATE BY DESIGN No account. No ads. No tracking. Your entries stay on your phone and are included in your phone's own backup. Export them as CSV whenever you like. H2OK PRO: ONE-TIME PURCHASE Water tracking is free, forever, with no limits. If you also want to count other drinks, H2OK Pro adds sparkling water, tea, coffee, ayran, milk, juice, soft drinks and sports drinks, each with cups that suit it, plus caffeine tracking with a 400 mg daily guide and totals for every drink. Pay once, it's yours. No subscription. Coffee and tea count toward your goal: in normal amounts they hydrate about as well as water. Available in 35 languages. H2OK gives a general estimate, not medical advice. If you have kidney or heart problems, take regular medication, or are pregnant or breastfeeding, ask your doctor about how much to drink.
