Unbuzz vs Caffy

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.
