Crema: Caffeine & Cup Log

Caffeine outlasts the cup. Your body clears about half of it every five hours, so an afternoon latte is still with you at bedtime. Crema keeps track of it for you, so you know when to have your last coffee. LAST CALL Each of your usual drinks shows the latest time you can have it and still be under 50 mg of caffeine at bedtime, a level generally considered low enough not to disturb sleep. Every drink you log moves it earlier. SEE TONIGHT BEFORE YOU ORDER Tap a drink to see what it would do to tonight: how much would be left at bedtime, and when you’d be under 50 mg. Then log it with one tap. TUNED TO YOU Tell Crema your bedtime and how long coffee lasts for you. People clear caffeine at very different speeds, and Crema’s estimates follow your answer. TRENDS How much caffeine was left at bedtime, night by night. When your last drink usually is. Your daily total against your limit, and which drinks bring the most caffeine. A HEADS-UP An optional reminder 30 minutes before last call for your usual drink, only on days when there’s still time. QUICK TO LOG Your usual drinks are a tap away. Type any other drink and Crema estimates its caffeine from the drink and size, or take a photo of the cup and it fills in the drink, shop, and size, reading it on your iPhone. SIRI AND SHORTCUTS “Log my usual” and “Can I still have coffee?” work with Siri, Shortcuts, and the Action button. PRIVATE Your log stays on your iPhone. No account, no ads, no tracking. Export everything as a spreadsheet at any time. Caffeine amounts and how quickly caffeine wears off are estimates based on typical drinks. They are not medical advice.
