Caffeine Tracker Apps: 7 Options With Screenshots (2026)

By Mira Hartwell•Published September 25, 2026•Updated October 10, 2026•11 min read

The useful difference between caffeine apps is what they help you decide. A remaining-caffeine graph can help you think about your next drink. A combined water-and-coffee log saves you a second app. A habit calendar helps you follow a rule such as “no coffee after lunch.”

For a detailed drink database on Apple devices, start with HiCoffee. For an option on both iPhone and Android, look at Caffeine Clock. If you want to see the interfaces before installing anything, every app below has two screenshots from its developer or store listing.

How this comparison was made: We checked official product pages and US store listings on 8 October 2026. This is a comparison of documented features and published screenshots; we have not run hands-on logging-speed or accuracy tests. Prices can differ by country and change over time. We make HabitBox, which is included as a habit-tracking alternative with its limitations stated below.

The apps, with screenshots

1. HiCoffee — for a detailed drink database

HiCoffee makes sense if you want to log a specific drink and see an estimate of the caffeine still in your system. Its listing describes more than 2,500 branded drinks, custom entries, a home-coffee calculator and Apple Health integration.

The screenshots show a current-level dashboard beside the drink picker, including brand filters and serving sizes. That is the distinction to look for: today's intake and estimated caffeine remaining are different numbers.

The trade-off: It is limited to Apple devices. The current iPhone app requires iOS 18; Mac support requires macOS 15. Premium has a one-time option as well as subscriptions, but check which features you need before paying.

2. Caffeine Clock — for iPhone and Android

Caffeine Clock is an option for readers comparing both mobile platforms. Its developer describes a model that includes absorption as well as clearance, with a current-level estimate and a bedtime forecast.

The screenshots show the estimated active level and projected curve, followed by a searchable drink-entry screen. Use that forecast as a planning aid; a detailed graph does not make the estimate a measurement of your body.

The trade-off: The free version contains ads. Paid ad removal is available, but check the offer in your own store rather than assuming the two platforms have identical pricing or features.

3. Caffeine App: Daily Tracker — for caffeine and water together

Caffeine App: Daily Tracker, by Oleg Mueller, combines caffeine and hydration tracking. It supports custom drinks, Apple Health and Apple Watch, plus a timeline and a notification based on your selected caffeine threshold.

The screenshots show the caffeine overview beside a log containing both water and caffeine entries. This is worth considering if you want both logs without maintaining two apps.

The trade-off: The current listing is for iPhone and Apple Watch, with iOS 18 and watchOS 11 requirements. Pro is listed as a $4.99 purchase. The sleep threshold is an estimate, not a guarantee that you will fall asleep at the displayed time.

4. RECaf — for frequent drinks and Siri logging

RECaf focuses on making repeated entries convenient. The developer describes a Frequent list, Siri shortcuts and actionable notifications, with caffeine records stored in Apple Health.

The screenshots show the history dashboard and Frequent drinks list. The developer website supplies older interface imagery, so these screens should not be read as a promise of the current visual design. Its documented strength is logging and reviewing caffeine alongside sleep history. We could not verify a live remaining-caffeine curve from the official listing, so do not choose it assuming that feature is included.

The trade-off: Logging and other Premium features require a subscription after the 14-day trial. The US App Store listing shows $9.99 per year, with no permanent unlock listed.

5. Alyx — for a last-caffeine alarm

Alyx has a specific feature called Last Call: a time for your final caffeine intake, with an optional alarm. The developer also describes a caffeine forecast, Apple Health integration and sleep comparisons.

The first screen shows a weekly caffeine graph and estimates for bedtime and clearance. The second shows the Last Call settings with a 2:30pm alarm. These are developer-provided example screens; that time is not a recommendation for everyone.

The trade-off: It requires iOS 26. A free plan is available; the developer lists Club at $1.99 monthly, $9.99 annually or $24.99 once. Check the free-plan limits against the features you want.

6. Caffeine Tracker — a paid Android option

Caffeine Tracker by Sean Schendel uses a pie chart to distinguish absorbed, unabsorbed and metabolised caffeine. It also supports custom doses, target-zone notifications and CSV export.

The screenshots show the pie-chart overview and a separate graph of past and projected caffeine levels. The breakdown is useful if a daily milligram total does not explain what the model expects to happen next.

The trade-off: The interface is more utilitarian than the other examples. It costs $1.49 on US Google Play at our check. An earlier version of this article incorrectly called it free; we have corrected that claim.

7. HabitBox — when coffee is one habit among several

HabitBox is our own general habit tracker. It belongs in this comparison only if your goal is following a routine, such as keeping to a cup limit or stopping coffee after lunch.

The actual HabitBox screens show the habit dashboard and the habit-creation form. They are not a caffeine dashboard. You can create a habit for your chosen cut-off and set a reminder, then review completed days alongside your other routines.

The trade-off: HabitBox has no caffeine database, absorption model or remaining-milligrams forecast. Choose one of the dedicated caffeine apps above if you need those calculations. It is free to start on iOS and Android, with optional Plus purchases.

What to check before choosing

The screenshots are a starting point. Before paying, try the tasks that matter to you:

  • Find your usual drink. Check the brand, serving size and caffeine amount. If it is missing, see whether a custom entry is easy to reuse.
  • Correct yesterday's entry. An app that cannot comfortably backdate or edit a drink will make your history harder to maintain.
  • Inspect the forecast. Look for the assumptions behind it, such as half-life and your chosen bedtime. Do not confuse daily intake with caffeine estimated to remain.
  • Check the upgrade screen. Confirm that the chart, reminder, widget or export you want is included in the price you are considering.

For a quick calculation before installing anything, our caffeine half-life calculator lets you explore how a drink's timing changes the modelled amount left at bedtime.

What the caffeine curve can and cannot tell you

A tracker combines the dose you enter with a mathematical model. It cannot measure your personal caffeine level or promise that a particular drink will leave your sleep unaffected. To see what a later cup does to your nights, pair the log with a sleep tracker app and compare weeks rather than single nights.

Caffeine metabolism varies between people and is influenced by factors including genetics, medications and smoking, as described in Nehlig's review of caffeine metabolism. A forecast can help you compare the model's prediction for an earlier drink with a later one. It should not be treated as a personalised safe-intake recommendation.

For a general ceiling, the FDA cites 400 mg a day — about two to three 12-ounce cups of coffee — as an amount not generally associated with negative effects in most adults (checked October 2026). Talk to a clinician about a lower limit if you're pregnant, trying to become pregnant or breastfeeding, take medication, or have a heart or other medical condition; the FDA notes that some conditions and medications make people more sensitive to caffeine.

Serving size matters too. A mug of home-brewed coffee and the database's default “coffee” may contain different amounts. Check the entry rather than treating an exact-looking number as a lab result.

Caffeine tracker app FAQ

Which one should I start with?
Start with the task you need. HiCoffee offers a detailed drink catalogue on Apple devices; Caffeine Clock has iOS and Android versions; Caffeine App combines water and caffeine; RECaf focuses on convenient logging; Alyx has a Last Call alarm. HabitBox is an alternative for following a routine rather than estimating caffeine levels.
Is Caffeine Tracker by Sean Schendel free?
No. The US Google Play listing shows a $1.49 purchase as of 8 October 2026. Several other apps here offer free downloads, but those should not be confused with unrestricted free access.
Are these screenshots from hands-on tests?
No. They are screenshots published by the app developers on their official sites or store listings. Every gallery includes its source. They show the interfaces, but do not demonstrate reliability, logging speed or the accuracy of the underlying model.
Can HabitBox replace a caffeine tracker?
It can help you follow a chosen behaviour, such as avoiding coffee after lunch. It cannot tell you how many milligrams remain in your system. If that is the number you want, use a dedicated caffeine tracker.
