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.

Allerdings gibt es sie aktuell leider nur auf Englisch. Ich würde mich riesig freuen, wenn es in Zukunft ein Update mit einer deutschen Übersetzung geben würde – das würde die Nutzung um einiges ergreifender und einfacher machen! Vielen Dank für die tolle App. ### 5/5 — Lovely designed *2026-02-13* Just wanna spread some love. You can feel that this app is made with heart, so it deserves to be appreciated :) **Developer response:** Thank you so much! I did work hard on it ❤️ ### 5/5 — Awesome App *2026-02-03* 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! **Developer response:** Thank you so much!!! ### 5/5 — Whimsical and fun *2026-01-30, version 1.0.8* Delightful to use! ✨ ### 1/5 — Poor Apple Health Integration *2026-01-03, version 1.0.8* pretty app, that does not read existing data from Apple Health which eliminates the utility. ### 1/5 — Worthless app doesn’t work *2025-12-27* The app doesn’t work. You can try entering caffeine at later hours and the graph of sleep impact doesn’t change it’s hard coded, I was tricked into the subscription and can’t even refund even though I don’t use it. **Developer response:** Hey there Alex, sorry you had issues. 1) If data isn't saving, make sure you have both Sleep and Caffeine read+write permissions enabled for Apple Health. 2) The graphs are not hard coded for sleep impact, if you tap the button in the top left corner -> "Learn More" you'll get a detailed report of how it comes up with the results. 3) You can always get a refund via the App Store. ### 5/5 — Indispensable *2025-11-21, version 1.0.8* If you love your caffeine but want to know more about how it affects you, this is the app. Fantastic. ### 5/5 — Finally *2025-11-20* 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 ⌚️ ### 5/5 — I ❤️ Alyx *2025-10-29* 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 ☕️ **Developer response:** Dude thanks so much for this review, seriously made my day!! ### 5/5 — Clean App Experience *2025-10-17* Feels premium and fun to use. **Developer response:** Love to hear it!! Keeps me going! ## Frequently asked questions about Caffeine Tracker ### How does Alyx track caffeine? Alyx allows you to log various caffeine sources like coffee, espresso, and energy drinks.
