Hydria: Water Tracker

Drink enough water — finally. Hydria turns hydration into a habit you actually keep, wrapped in water we render ourselves: a Metal fragment shader that catches the light, refracts through the glass, and answers every log with a satisfying "sploosh."

Most water apps nag you, then make you feel guilty. Hydria does the opposite — a calm coach that meets you on your iPhone, your Lock Screen, your Mac and your wrist, with a goal built around YOUR body and a tap-to-log so fast it never gets in your way. And one off day won't ruin your streak.

WATER THAT IS RENDERED, NOT ANIMATED
• The liquid is computed on the GPU every frame by a shader we wrote — there is no video, no GIF and no animation file anywhere in the app.
• Tap the bottle: a ripple runs out across the surface and decays over about a second.
• It takes its colour from the drink you logged, and it degrades honestly — Reduce Motion gives you a still, correctly lit frame, and Low Power Mode switches to a lighter renderer to spare your battery.

WHY HYDRIA
• A goal that's actually yours — calculated from your weight, activity, climate and schedule.
• Log in one tap — quick-add chips, custom amounts, or "Hey Siri, log water in Hydria."
• Streak Freeze (Premium) — a budget of forgiven days, so one off day doesn't reset your streak.
• Reminders that respect you — paced to your day, and quiet when you're already ahead.
• One app across iPhone, iPad, Apple Watch, Mac and Apple Vision Pro. On Mac it puts a drop and today's percentage right in the menu bar, with a click-to-log menu.
• No ads. Ever. No account, no sign-up — your data stays on your device and in your own iCloud.

ALCOHOL COUNTS AGAINST YOU
• Not all drinks count the same: water 1.0, tea 0.95, coffee 0.80.
• Beer, wine and spirits count NEGATIVE — log a beer and today's total goes DOWN, just like real life.
• Calories and caffeine come from the same table, automatically.

HEALTH CHALLENGES (PREMIUM)
• Take on a challenge with a friendly buddy cheering you on — Sober Streak with Barley the Bear, Ditch the Soda with Sunny the Sloth, Caffeine Curfew with Koa the Koala, Water Purist with Otis the Otter.
• They're abstinence goals scored against your real drink log, not just a counter.
• Finish a challenge and share a beautiful card to your Story — bragging rights included.

Payment is charged to your Apple ID account at confirmation of purchase. A subscription renews automatically at the end of each period unless auto-renew is turned off at least 24 hours before the end of the current period; your account is charged within 24 hours prior to renewal. You can manage or cancel your subscription, and turn off auto-renew, in your App Store account settings after purchase. Lifetime is a one-time purchase, not a subscription.
