Hydria
Read full descriptionHide full description
Drink enough water ā 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 ā 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 ā 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 ā 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 ā calculated from your weight, activity, climate and schedule. ⢠Log in one tap ā quick-add chips, custom amounts, or "Hey Siri, log water in Hydria." ⢠Streak Freeze (Premium) ā a budget of forgiven days, so one off day doesn't reset your streak. ⢠Reminders that respect you ā 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 ā 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 ā 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 ā 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 ā 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 ā 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.

Snap a photo of your plate and see calories, protein, carbs and fat in seconds. No kitchen scale, no scrolling through endless lists. One photo is enough. CaloriPanda is a healthy-living assistant that knows every cuisine. Home cooking, street food, the place around the corner, a dish you tried on vacation: it recognizes what's on your plate, from a bowl of lentil soup to sushi, from stuffed grape leaves to a burger. Turkish food included, under the names people actually use, so you're not stuck picking the closest thing on a list and hoping for the best. This isn't a diet. It's just a clear picture of what you're eating, one day at a time. SNAP A PHOTO ⢠Take a photo of your plate and get portion and calorie estimates in seconds ⢠Not quite right? Change the food or the portion with one tap. The portion you pick is the one that opens next time you log that food ⢠Or pick a photo from your camera roll and log the meal just as fast SEARCH, BARCODE & LABELS ⢠Search the food library for everyday staples, home cooking and packaged products ⢠Scan the barcode on a packaged product and add it right to your diary ⢠No barcode on it? Point the camera at the nutrition label and it reads the table for you ⢠Re-add anything you saved with a single tap, and if you forgot yesterday, pick that day on the home screen and log it there SAY IT OUT LOUD ⢠Tap "+" twice and just say it: "a plate of lentil soup, two slices of bread, a 30 minute walk". Food, water and exercise all go in at once ⢠Ask about your own days too: how last week went, what you eat most often, how much you have left today ⢠Speak Turkish, English or Arabic WATER & EXERCISE ⢠Log water as you go and see how close you are to your daily goal ⢠Add the calories you burn when you move, and get them back in your daily total ⢠Connect Apple Health and your steps keep the day's goal up to date on their own SEE YOUR PROGRESS ⢠Calories, protein, carbs, fat and your health score: one screen, one glance ⢠Your weight chart and your daily streak, always in view ⢠Save the meals you eat most to favorites so logging takes seconds, not minutes ⢠Want it on paper?

Verdict
The clearest difference is update cadence: CaloriPanda at every 2 days against Hydria's weekly. Hydria's advantage is device support (5 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
