Hydria

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. START FREE Log water, coffee and tea, hit a personalized goal, set a daily reminder, see your week, sync to Apple Health and use the Apple Watch app — free, forever. No account needed. GO PREMIUM Health Challenges, Streak Freeze, every drink type with calories & caffeine, month and 90-day trends with your hydration score, smart adaptive reminders, all widgets, complications and Live Activity, achievements, and iCloud backup. Hydria Premium is an auto-renewable subscription, with a one-time Lifetime option if you'd rather pay once. The plans and the exact price for your country are shown in the app before you buy. 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.

Verdict
The clearest difference is update cadence: Hydria at weekly against AlcoBot's every 3 weeks. Hydria also leads on device support (5 vs 2). On price, ads, in-app purchases and iOS requirement there is nothing between them.
