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.
