Meet your fish. Your fish needs you to drink water. Glug is a hydration tracker with a virtual fish that lives or dies based on how much you drink. When you hit your water goal, the tank fills and your fish thrives — happy, glowing, swimming laps. Miss a day? Watch them gasp. Miss two? They're belly-up. Three? Skeleton. This isn't a step counter. It's a consequence. Here's how it works: • Set your goal — Glug calculates a personalized daily target from your weight, age, activity level, climate, and what else you drink. • Drink water, fill the tank — log each drink and watch the water level rise. Every oz counts. Your fish is watching. • Unlock their world — keep your streak alive to unlock decorations: rocks, plants, a castle, a treasure chest, a sunken ship, and a companion fish. The more you drink, the richer the tank. Your fish has six health states: thriving, happy, worried, gasping, belly-up, and skeleton. The push notifications don't pull punches. Expect: "YOUR FISH IS GASPING", "POV: you killed [name]", and "fish is currently flopping. log something." You set their name. That makes it worse. Glug Pro unlocks the app — the tank, the fish, decorations, widgets, and every future update. $4.99/month · $19.99/year with a 7-day free trial · $29.99 lifetime, one time. Download Glug. Your fish is counting on you. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://glug-privacy.pages.dev
