Caffeine Tracking by RECaf2026.1 - App Store

Many apps record caffeine, but most never learn about you and your habits. What if your caffeine tracker were smarter?

. One-tap logging of your most-frequent sources
. Logging via voice with Siri shortcuts
. Smart reminders to keep you on track
. New insights into your caffeine routine with charts and detailed stats
. Integration with HealthKit, for secure data storage

RECaf was designed and built to take advantage of all the latest and greatest features available to you on your phone. And the best part-you can try it for 14 days, risk free, with an auto-renewing annual subscription thereafter.

More features include:

. Completely customizable source list. Add any sources you like and adjust the caffeine levels, measurement units, and icons.
. Easy-access to your most frequent sources. RECaf automatically brings the caffeine you use most often to your fingertips
. Shortcuts for any source-from the source list, choose any source, record a unique audio phrase, and then log that source with your voice.
. A favorites panel grants easy access to those sources you like but don't log as often.
. Interactive notifications with machine learning - RECaf will study your caffeine intake over time and learn what time (if any) you tend to log on a particular day. So if you usually have coffee at 10am on Mondays, skip Tuesdays, then have green tea at 7am on Wednesdays, RECaf will send you quick reminders only on the appropriate days and at the appropriate times, if it notices you haven't yet logged your "usual." Adjust the time of the log right in the notification, and log with a tap.
. Statistics about your caffeine intake.
. Number of items logged today
. Number of mg of caffeine logged today
. Average items and mg over the past 7 days
. Average items and mg over the last 30 days
. Number of items logged in the past week past your designated "after hours" time
. Breakdown of logging percentages by time of day (morning, afternoon, evening)
. The last item logged and percentage of entries
. The most frequent item logged and percentage of entries
. Your typical "routine" for each day of the week. (Time and source)
. Sleep analysis: How does caffeine effect your sleep?
. A comprehensive list of all items logged in your HealthKit database. (Even those not logged with RECaf.)
. The ability to edit your entry dates and amounts. Or delete entries that may have been logged erroneously.

Download and try RECaf today. A yearly subscription to our 12-month premium features will automatically renew 24 hours prior to expiration of your free trial. To turn off auto-renew, visit subscription settings inside the Settings app on your device.

Thanks to everyone who reported issues and helped make RECaf better. If you would like to leave a review, that is always appreciated. 2020.4 11/15/2020 This version fixes some bugs, including water not properly logging when using shortcuts, some shortcuts not working properly for a small number of users, and sleep analysis miscalculating your total sleep time in some limited instances. 2020.3 09/13/2020 This version fixes a few critical bugs with decimal separators not being recognized when you tried to edit sources. 2020.2 09/09/2020 This is a big one. I wanted to revamp some of the underlying ways the app converts data, so that it could be far more reliable, and open up more possibilities in the future. Meanwhile, I didn't forget about the new features.

• Sleep analysis. If you are tracking your sleep with your phone or watch (using any app that stores sleep data in HealthKit) RECaf can now present you with some interesting analysis about how your caffeine intake affects your sleep. Do you sleep less when you've had more caffeine? Does it take longer for you to fall asleep when you have caffeine late in the day? Does it matter if you have caffeine later in the day vs. the morning?
• Hydration logging. Coffee and tea are mostly water, right? So why not log a water intake entry while logging your morning caffeine? For all entries that are measured in ml or fl oz, you now have the option to log a water entry automatically while you are logging your caffeine into HealthKit. Save yourself that trip to the water logging app. (Note: Shot-based drinks, doses, and mass measurements, such as your coffee ice cream, will not log water entries.)
• Reorder and quickly remove favorites. Now, right from the main tab, you can reorder or delete favorite sources.
• Improved communication between watch and phone.
• Many, many bug fixes and small usability improvements.
• Increased speed and reliability of data analysis.

Note: This version utilizes a new format for shortcuts. If you have been logging via your voice, you will need to set up new shortcuts. (The app will remind you, if you have older-formatted shortcuts on your phone.) 2020.1 09/07/2020
