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 ### 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 ### 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. ### 4/5 — Super App - paar weitere Infos werden top *2022-07-05* Super funktionale App, welche einem hilft, einen guten Überblick über seinen Koffein-Konsum zu bekommen. Um den langfristigen Konsum etwas im Blick zu haben, wäre ein monatlicher oder wöchentlicher Vergleich der konsumierten Mengen ganz sinnvoll. ### 4/5 — Not reading from health *2021-11-09* I use another app to add caffeine entries to health, and this app does not use that data despite the relevant setting is enabled and all requested health permissions are granted. Hope this is fixed eventually. **Developer response:** Hi JamesYUCNCN, Caffeine App does not read entries from Health, it only adds entries created in Caffeine App. This will be hopefully coming in the next year. Kind regards Oleg ### 4/5 — Leider ohne Widget… *2021-10-11* …ansonsten top! 👍 ### 3/5 — Close to perfect *2021-03-25* This is a great app but it’s lacking in the shortcut department. While it has shortcut support, it just brings you into the app to select the item. I would much rather have shortcuts that allows you to actually select a specific beverage for automated logging. ### 4/5 — Love it! But.. *2021-02-14, version 1.8.2* Fabulous concept. Lovely fast app. Easy to use. Would love more granular adjustment of units of measurement (fractions of a shot). Range of caffeinated beverages could be larger (like my fitness pal). ### 4/5 — Useful, but the UI is a little cumbersome *2021-01-26* The app is useful and works great, the user interface, however is a little cumbersome and not the greatest user experience one could imagine. It is questionable for example, why the button to consume a drink is very small and at the very top, i.e. rather difficult to reach. Configuring drinks is also a bit more complex as it needs to be. One feature that I would like to see is a simulation of what it would mean to consume a specific beverage, so that I could decide whether I would have another coffee or not. Anyways, these are all points that can be improved in the future and the app, as is, works fine! ### 4/5 — Gut, mit Potenzial nach oben. *2021-01-18* Die App ist gut. Eine Vielzahl von Sorten ist vorgegeben und man kann noch mehr hinzufügen. Was mir fehlt bzw. was ich mir wünsche, ist ein Widget. ### 4/5 — Pretty good, wish it had shortcuts integration *2021-01-16* The real value of this app is having preset drinks with their respective caffeine levels and giving you an estimated sleep time based on how much you have consumed. The app has integration with HealthKit for syncing metrics but I really wish it was more “automatible”. Would be perfect if you had Siri shortcut actions for logging a saved drink and getting the sleep time. ### 4/5 — The UI is terrible *2021-01-07* Difficult to choose amounts other than presets... and need to type in every entry. Even though “only $4...it’s a waste.. too bad.. the reviews I read were so positive 😢 ### 3/5 — Need other features *2020-10-16* Would really appreciate if the app allows you to track your mood and energy level throughout the day too so we can know how caffein actually affects us individually. Right now the app doesn’t give as much insight as I would hope on our coffee habit ### 5/5 — Great app. *2020-09-28, version 1.8.1* Does exactly what I need it to do and nothing more. ### 5/5 — Great app! Perfect integration with apple watch *2020-09-25* However, it would be nice if we could enter elimination rate factors such as whether the user is smoking, pregnant or taking some specific medications **Developer response:** Hi EricU95, caffeine processing in your body does not depend on your weight. Kind regards Oleg ## Most critical reviews (10 lowest-rated) ### 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! ### 1/5 — All presets missing in current version! *2020-10-20, version 1.8.1* The groups tab is now empty, and I don’t feel like re entering all that data 😫 ### 1/5 — No keurig *2018-05-28, version 1.4.2* What is wrong with all these apps? Nobody has k-cup data! For 3.99 I’d expect a full library of coffees. I want my money back ### 1/5 — Gut, aber... *2017-12-02* Eintäge die auf der Apple Watch gemacht werden, werden zwar in Health Kit eingetragen, aber nicht immer in die App selbst übernommen. Die Website von Bitgrainedbytes besteht lediglich aus einer Mail Adresse. **Developer response:** Hallo h_deis, das ist natürlich ärgerlich. Passiert das immer oder nur bei bestimmten Umständen? Was für eine Apple Watch nutzt du? Ja die Website existiert quasi nicht. Eine "richtige" Website lohnt sich leider nicht für so eine kleine App... Danke für deine Bewertung. Viele Grüße Oleg ### 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 ### 2/5 — Super Koffeintracker *2020-03-26* Ich nutze die App schon sehr lange und die Daten werden sehr zuverlässig auch in Health übertragen. Die Watch Komplikation ist sehr hilfreich . Update März 2020. Mit jedem Update kommen Darstellungsprobleme hinzu oder die App stürzt bei jedem Erfassen ab. Werde mich wohl nach einer Alternative umschauen müssen, da diese hier zuletzt vor 5 Monaten aktualisiert wurde. **Developer response:** Hallo Xococ, Danke für den Hinweis, ich werde die Fehler korrigieren. Viele Grüße Oleg ### 2/5 — Cloud Sync??? *2020-01-18* much needed :( ### 2/5 — App okay lässt aber Spielraum nach oben *2019-01-04* Hallo, Leider finde ich eure Datenbank an Getränken sehr klein. Ihr habt als Energiedrink als Beispiel nur Red Bull. Das löschen einzelner Kategorien ist lästig weil dann die Einträge zusätzlich nochmal löschen muss. ### 2/5 — very confusing UI *2016-02-05, version 1.0.1* adding custom entries is terrible ### 3/5 — Needs extra features *2021-08-03* I like it but it would be better if you could add drinks in ounces. Also would be nice to be able to look at use over time to see patterns instead of just one day really. ## Most praised reviews (10 highest-rated) ### 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. ### 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! ### 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. ### 5/5 — Helpful *2022-03-05* After years of consuming coffee by the ton, I decided to cut back. This app has been a great way to measure my progress. ### 5/5 — Funktioniert nicht mehr. *2021-04-28* iOS 14.5, auf der Uhr funktioniert es nicht mehr. **Developer response:** Hallo Maschuma, kannst du mal probieren ob ein Neustart der Apple Watch hilft? Viele Grüße Oleg ### 5/5 — Pretty good *2020-12-19, version 1.8.1* Would be nice to see widgets added for ios14. Also on the Apple Watch, It would be great to be able to choose which complication displays.. on some faces it shows a running total of caffeine consumed.. but on most it displays the last time I consumed caffeine. I’d love to be able to pick which one to display. ### 5/5 — Very Useful! *2020-12-15* Very useful app for determining your actual intake of caffeine with potential for taking in too much! Like WAY too much!! I was finally honest with myself in large part due to this app!! Sleep improvement has been genuine! ### 5/5 — Einfach und sehr funktional! *2020-12-11* Jeden Cent wert. Hat eine funktionierende Watch App. ### 5/5 — Tolle App *2020-10-20* Tolle App und tolle Apple Watch Complication. Ein iOS 14 Widget wäre klasse ... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
