Alyx is a silly way to track caffeine. Quickly log espresso, lattes or anything else and see how it affects your health, sleep or view other interesting stuff! It uses Apple Health to store your data privately, which means it also syncs with iCloud.
Of course, you can log caffeine here. Aside from being a coffee, espresso, energy drink, or general caffeine tracker and journal, there are some interesting things it can do:
- Figure out when your body will be caffeine free.
- Discover how much caffeine will be in your body at bedtime.
- Get your customized "Last Call" for caffeine every day, and set an alarm for it!
- See how caffeine consumption impacts the amount of sleep you get.
- View how caffeine will decline in your body over the next 12 hours.
- See if your caffeine consumption has been trending up or down lately.
- Tons of Siri Shortcuts.
- Tons of widgets!
- Create your own custom drinks, and have AI figure out the caffeine contents!
- A Hall of Fame for...caffeine consumption?
- Um, what else? Oh, tons of charts!
So yeah, you can see how caffeine affects your sleep, overall health, see how much sleep you'll lose, and more. I don't know, it's just a fun app. Download it or don't.
Love,
Alyx

I think this is my first App Store review, and I felt compelled to share that I thought it is pretty cool. I was looking for an app to track my caffeine consumption because it varies, daily, and occasionally I think I drink too much. This app is really good at educating me, and gently reminding me, how much caffeine I should be consuming. Also, I love the feature that shares how much sleep I can expect to miss out on due to my caffeine consumption. Great app and cool branding, too!

Honestly, such a great app! It’s really helped me sleep better and be more aware of my (excessive) caffeine intake. The app is beautiful, the widgets are great, and the nice humorous touches are greatly appreciated, matches my sense of humor perfectly! It’s fun to explore around the app and see those little Easter eggs everywhere. Just goes to show the developer loves what they do! If I could rate more than 5 stars I would ☕️

I don’t like it, I love it. 😉 Not only is it a well polished app, it’s actually super useful, and really fun. Who knew a caffeine tracker app could be witty & fun. 🤭⚡️ I really love how easy it is to use, and the sleep forecast is one of my favorite features. If you’re looking for a 5 star caffeine tracker app, look no further- update your phone, & download this app. 😄

I’ve been looking for an app just like this for a long time and someone finally delivered. It’s beautiful, has personality, and connects with my health app. One recommendation, it would be awesome if there was a watch app.
Developer Response
Thank you so much!! Definitely want to do a watch app as well ⌚️
Improved the entry editor with a cleaner layout and a more reliable delete flow.
Made logging, editing, and deleting caffeine feel faster and more responsive.
Smoothed out several charts so trends and sleep insights load more reliably.
Improved widget reliability with better cached data and fallback behavior.
Fixed 24-hour time display issues and polished smaller UI details.
As always, please enjoy Alyx responsibly :-D.
