Before your next coffee, check if it still fits your bedtime. Unbuzz is a caffeine tracker for coffee, tea, energy drinks and more, on iPhone and Apple Watch. Log what you drink, and before the next one, ask "Can I have another?": Unbuzz estimates how that drink would add up by your bedtime and answers right away. CAN I HAVE ANOTHER? Pick a drink and see whether it still fits your bedtime estimate, before you log anything. Your last drink is filled in, so the answer takes one tap. Compare half a serving, an hour earlier or decaf; nothing is logged while you compare. When the answer is no, see how much still fits and compare a lighter drink you often have. FIND YOUR DRINK FAST Search a catalogue of branded coffee shop drinks, energy drinks, sodas and teas, with each size listed separately. Your recent drinks come first, even when you search. Scan a barcode or create your own drink when you need to. A FREE WIDGET Add the free "Can I have another?" widget to your Home Screen or Lock Screen and see the answer at a glance. ON YOUR APPLE WATCH The Apple Watch app and complications show your current estimate. With Pro, log drinks from your wrist. KNOW WHEN TO STOP Follow an estimate of your caffeine level through the day, with your bedtime level and today's drinks, so you can see when your last coffee of the day should be. With Pro, get a reminder before your last call. CUT BACK GRADUALLY With Pro, follow a plan toward one of two goals: a smaller daily total or an earlier last call. LEARN IT IN A MINUTE Short how-to videos show each part of the app, with captions in your language. FREE AND PRO Free: logging, drink search, barcode scan, custom drinks, the "Can I have another?" check and its widget, the Apple Watch app and complications, Apple Health, and the last 14 days of history. Unbuzz Pro (subscription or one-time purchase) adds full history and trends, more widgets including quick log, logging from Apple Watch, last-call reminders and the plan to cut back. PRIVATE BY DESIGN The calculations run on your device. No account is needed. Apple Health is optional. Analytics are optional and off until you agree. Caffeine levels and timing are estimates. Individual responses vary. Unbuzz does not measure caffeine in your body, predict when you will fall asleep, or provide medical advice.

About

Hydration Break Water Reminder

Features
Read full description

Hydration Break is a weather-smart hydration reminder and water reminder app. Most reminder apps give everyone the same fixed goal — Hydration Break watches the weather for you: on hot, humid days your water goal rises automatically, because science says it should. PREGNANCY & BREASTFEEDING HYDRATION During pregnancy and while breastfeeding, your body needs noticeably more water — and it's worth tracking closely, because that need isn't a fixed number. Hydration Break recalculates your personal goal every day from the feels-like temperature (heat index), humidity and UV at your location, so on hotter days your target rises automatically. Set pregnancy or breastfeeding in your profile and get a daily amount built for you and your baby, with gentle reminders that keep you on pace all day. WEATHER-SMART DAILY GOAL Your hydration goal adapts to the feels-like temperature (heat index), humidity and UV at your exact location, hour by hour — included in every plan, not a paid add-on. SMART WATER REMINDERS Gentle, reliable drink reminders that speed up on hot days and pause while you sleep. Set your own reminder interval and active hours. Log water in one tap straight from the notification — no need to open the app. HYDRATION BREAKS FOR SPORT — LIKE THE WORLD CUP Start a session (football, American football, basketball, tennis, running, golf and more) and get a hydration break every 15 minutes — with a live countdown in your notifications and a per-break amount sized to your sport, the heat and your body weight. A no-time-limit mode is included for open-ended workouts. APPLE WATCH APP INCLUDED Log water from your wrist with a one-tap confirmation, start sport sessions with 15-minute hydration breaks on the watch, see live progress on your watch face, and add water right from the Smart Stack — everything stays in sync with your iPhone. SCIENCE-BASED, PERSONAL Your goal is built from your weight, age and gender, adjusted for pregnancy, breastfeeding and kidney conditions — with references you can read in the app (EFSA, NOAA, ACSM, AUA/EAU). Not a one-size-fits-all "8 glasses". EFFORTLESS LOGGING One-tap bottle chips you name and color yourself, quick-add buttons, a home screen widget with live progress, and drink types that count honestly (coffee counts 80%, tea 90%). STAY ON TRACK Morning briefing with today's weather-adjusted goal, smart pace reminders that speed up on hot days, a proactive heat alert before the hottest hours, a goal celebration and a gentle last call before bed. Streaks keep you motivated. PRIVATE BY DESIGN No account. Your health data never leaves your device. No ads, no data sales. Units: ml or fl oz, kg or lb, °C or °F — smart defaults by region. Try everything free for 7 days, then continue with a single affordable subscription. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings → Apple Account → Subscriptions. Hydration Break provides general wellness guidance, not medical advice.
