What Dropkin does
Log water in one tap, in ounces or liters, watch your bottle come alive and build a hydration routine that fits your day.
Dropkin is a water tracker and water reminder built around the bottle you already carry. Save it once, tap it whenever you finish it, and get on with your day. No account, no ads, and it works offline.
Pick oz or mL and liters on the first screen. Bottle sizes, quick amounts and goal steps use round numbers in your unit (8, 16, 24 oz or 250, 500, 750 mL), and your goal shows the other unit beside it. Switch anytime; your history converts exactly.
