About

WaterDone

Features

WaterDone is the lightest way to keep sipping before you get thirsty. Had a sip? Tap once. That's the whole app. No amounts to type. No daily target. The goal is a rhythm: another sip within the interval you choose. A little drop dries out as time passes and fills up when you drink, and a gentle word tells you how you're doing — "Hydrated", "Time for a sip". • One tap from your Lock Screen or Home Screen widget, without opening the app • See when your next sip is due, right on the home screen • A gentle nudge before you dry out. You pick the interval (2–4 hours) and the hours it can reach you. Works fine with notifications off, too • Tapped by mistake? Undo in one tap • A streak and a simple calendar of every sip • No account. Everything stays on your device Hydration that doesn't feel like homework. WaterDone is not medical advice and does not calculate how much water you need.

Hydration is more than reaching a number. Gulpo helps you understand the pace behind it. The pace line shows where you could be by now, so you can see at a glance whether you’re on track, ahead, or falling behind. Tap it to see exactly how much. Log the way that feels natural. Manually choose a beverage and amount, say what you drank and how much all at once, or point the camera at your drink. Carry a bottle? It gets even easier. Just tell Gulpo how much of it you finished. Save the drinks you reach for often, from your morning glass to your desk mug, so they’re always close by. However the drink happened, there’s probably a quick way to log it. Now you’ve got one less excuse not to log :) Coffee, tea, milk, juice, smoothies and more all contain water. Gulpo accounts for the water in each drink instead of treating everything as plain water. Some days need more water than others too, so weather, workouts and details you choose to share through Apple Health can help Gulpo adjust your daily goal. There’s no Gulpo account and no sign-up. Your data stays on your devices and can sync through your own iCloud account. Gulpo doesn’t need to know who you are to know how much you drank. Gulpo Reserve is available as a monthly or yearly auto-renewing subscription, or a one-time lifetime purchase. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your Apple Account settings.
