Caffeine Tracking by RECaf vs Water Tracker CoffeeWatch

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. • Half Life - Caffeine remaining in your system • 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.

CoffeeWatch is a caffeine tracking app designed for people who love coffee and also care about how their body feels. For the first time, you can truly see your caffeine level in your body and your 24-hour metabolism curve—no more drinking by gut feel, no more pushing through on sleepless nights. Use data to protect your clarity, focus, and sleep. #Why We Built This App We’re a group of people who’ve survived countless late nights — powered by coffee. A “wake-me-up” cup in the morning, a “keep-me-going” cup in the afternoon, and a “let-me-finish-this-deck” delivery coffee at night. Some days it took five or six cups just to “look okay” in a meeting. But instead of feeling more stable, we ended up with: • Faster heartbeats, trembling hands, anxiety • Feeling more awake at night but sleeping lighter • And waking up even more tired — only to drink again It’s a loop: fatigue → more caffeine → worse sleep → more fatigue. We realized caffeine itself isn’t the enemy — The real problem is that we don’t know our current state. • How much caffeine is still in my body right now? • If I drink this cup, will I still be able to sleep tonight? • Am I already over my safe limit? So we made CoffeeWatch. --- # Features 1.
