Hydra
Read full descriptionHide full description
Hydra is a hydration tracker built around a single gesture: drag up anywhere on the home screen and watch the water rise to where you logged. Most water apps use a generic 2L target. Hydra calculates yours from your weight, sex, activity level, and climate β then bumps it up automatically when you take creatine. Because creatine pulls water into your muscle cells, you actually need more. DESIGNED AROUND THE WAY YOU DRINK β’ Drag to pour β pan up anywhere on the home screen β’ Quick-add presets for a glass (250ml), bottle (500ml), or shaker (700ml) β’ Custom amounts for anything in between β’ A live water-level background that fills as you progress CREATINE-AWARE TARGETS β’ One-tap daily creatine pill β’ Target adjusts automatically: +500ml per 5g dose β’ Personalized baseline from weight, sex, activity, and climate STREAKS THAT FORGIVE A BAD DAY β’ Daily streak counter β’ Personal best tracking β’ One streak freeze per week β’ Milestone glow effects every 7 days PRIVATE BY DEFAULT β’ No account, no login, no email β’ No analytics, no trackers, no ads β’ Everything stays on your device Drag to pour.

OneScoop

OneScoop is the simplest way to take creatine every day β and now to drink enough water. ONE TAP A DAY Open the app, tap Yes, done. Your streak, history and supply update on their own. You can also log from widgets, the Lock Screen, Control Center, Siri or your Apple Watch. On a loading phase, you can split your dose into portions. WATER, JUST AS SIMPLE Set your glass, shaker and bottle once, then one tap adds the right amount. The glass fills as you go, and a pace line tells you whether you're on track. Not sure how much to drink? The creatineβwater calculator suggests a goal from your weight and dose. BADGES WORTH SHARING Earn medals for your creatine and water streaks β 7, 30, 100 and 365 days β and share them to your story. REMINDERS THAT DON'T NAG A creatine reminder only on days you haven't logged yet. Simple water reminders at the interval you choose, never at the same time as your creatine reminder. And a heads-up a week before your tub runs out. ONESCOOP+ β ONE-TIME PURCHASE, NO SUBSCRIPTION - Detailed weekly and monthly reports with charts - Add water without opening the app: widgets, Lock Screen, Control Center, Siri - Apple Watch: add water with the Digital Crown - Smart reminders that learn when you usually drink and only nudge you when you fall behind - Creatine reminder right after your workouts - Apple Health: water syncs both ways, and your goal rises on workout days - Custom app icons and CSV export PRIVATE BY DESIGN No account, no ads, no tracking. Your data stays on your devices and in your own iCloud. OneScoop is not a medical app. Water goals, the calculator and saturation estimates are not medical advice.
