### 4/5 — Super App

*2026-07-06*

Super App, nur leider kann ich sie nicht auf der Apple Watch verwenden ohne die pro App zu zahlen ist das so normal ? 
Finde es sehr schade da ich sonst alles wirklich gut und übersichtlich finde. Nur möchte ich das auf Arbeit auch gern schnell über die Uhr erledigen und nicht per Handy. Falls ihr eine Lösung dafür habt wäre ich euch dankbar für eine Antwort. Dankeschön schonmal 👍🏻

**Developer response:** Hallo Melli7399, du kannst maximal 25 Einträge erstellen, ab dem 26. Eintrag musst du den In-App-Kauf tätigen. Viele Grüße Oleg

### 5/5 — Great UI, Useful Info

*2026-03-31, version 2.1.1*

If the data it provides are accurate, and I have no reason to believe they’re not, this is a wildly useful app for me. It’s 11AM, and I already have more than 12 hours worth of caffeine in me. Add to that the colas I have after work, and I can see why I have difficulty getting to sleep at night. Great app, great UI.

### 2/5 — Used to be better

*2026-03-06*

Recent changes have really bogged down the performance of this app. Now you can choose to also track water consumption, but that also slows down the app quite a bit and makes graphs too small to be useful. But at least you can turn that option off. 

Most recent change added a bar chart of past daily total caffeine, which again is nice but now you have to wait a long time for the graphics to update before the app is even responsive! And there is no way to turn off the additional chart.  And it too makes the daily caffeine level graph too small to be useful. 

Please add the ability to turn off the bar chart, and make the graphics space taller so graphs can actually be read. (It’s fine if you have to scroll slightly to see everything).

For an ad-free app it’s still pretty good.

**Developer response:** Hello Bykyrb, thank you for your review. I will look into this. Kind regards Oleg

### 5/5 — The best caffeine app!

*2025-10-23, version 1.9.0*

I’ve used this for years to slowly stop my  coffee habit without the crushing headaches. It’s so easy to use and has all the measures I need. I just reduce my sleep ready level slightly every few days and monitor the timing of my daytime coffee. Works a treat

### 5/5 — Excellent

*2025-01-28*

This app really helps me make sure I can fall asleep easily at bedtime. I like the ability to customize the target amount of caffeine per day, at bedtime, and adjust bedtime. I find it to be an accurate predictor of how long it will take me to fall asleep. 
There is one minor bug in the latest version: when logging a new amount the “sleep ready” time shows the current time. It used to correctly show the time I’d be ready for sleep if I took that amount of caffeine, which was helpful in deciding what to consume. 
And there are some quirks, like when you add a new custom amount you can’t rename it until after adding it. And newly added custom amounts appear at the very bottom of the list instead of the top. But for an ad-free app it’s great!

### 4/5 — Anschauliche Darstellung und Health Verknüpfung - top

*2024-05-24*

Die App macht genau das, was ich mir erwartet und erhofft habe. Sehr einfach und intuitiv anzuwenden - dabei graphisch sehr gut aufgebaut.

Allein fehlt mir ein Widget…
Das wäre dann der 5. Stern

### 1/5 — Useless App

*2023-08-01, version 1.9.0*

Maybe there is something I missed with this app, but bought it a couple days ago and, unless there are directions I am aware of, this app was a complete waste of money. I wish I could return it for a refund!

### 4/5 — Great app! Couple minor suggestions

*2023-06-28*

Love this app! Would definitely recommend it if you are at all interested in your daily caffeine consumption/looking at improving your sleep! 

For the developer, I have a couple suggestions.

1.) I do shift work, so my bed time is in the morning. Up until midnight, the app will say I’ve consumed too much caffeine because it cannot process the time differential for the next day.

2.) The history on the app could be better to show now much total caffeine you have consumed each day. 

The app is great overall still. Very helpful to see real time estimated caffeine levels!

### 4/5 — Does the job, mostly

*2023-02-15*

This app does a pretty good job tracking caffeine intake in its many forms. I like the graph showing how it slowly dissipates from your system. Americans should note that many of its preloaded caffeine types are products and stores found in Germany since the developer is presumably German. It’s nice that you can add your own categories and forms of caffeine. I added dark chocolate to my list of groups. 

The app could be improved by allowing users to set physical characteristics that determine caffeine affects each user according to body weight, or other factors.

### 5/5 — Apple Health Integratiom

*2023-01-25, version 1.9.0*

This is a great app. The UX/UI is beautiful and intuitive. Syncs with Health for easy long term tracking.
