How Jawbone’s App Helps Track Caffeine and Sleep

If you’ve ever felt like your morning coffee habit is more necessity than choice—or if you’ve wondered whether that afternoon espresso is ruining your night—you’re not alone. Many people rely on multiple cups of coffee just to feel functional, believing caffeine is the only way to stay alert. But how much is too much? And what does it really do to your sleep?

Jawbone’s free iOS app, Up Coffee, helps you log your daily caffeine intake—from coffee, tea, and energy drinks—and estimates how long it will take for the caffeine to clear your system. Based on data from 1,600 Jawbone UP users and 5,000 nights of sleep, the app shows when your body is likely to shift from stimulated to ready-for-rest. After 10 days of use, it reveals that 100mg of caffeine can delay your sleep.

What Is the Up Coffee App?

Up Coffee is a standalone smartphone application developed by Jawbone. It’s designed for iOS users and is completely free. The app allows you to manually input your daily consumption of caffeinated beverages, including coffee, tea, and energy drinks. You select the type of drink and approximate size or strength, and the app calculates your current caffeine level throughout the day using a simple visual meter: low, moderate, or high.

How Does Caffeine Affect Your Sleep?

Jawbone analyzed sleep data collected from 1,600 users wearing its UP and UP24 fitness trackers over 5,000 nights. The findings were clear: people who slept for around seven hours per night consistently reported better outcomes. They felt more awake, focused, productive, and even more attractive. While “feeling attractive” may be subjective, the other metrics point to the importance of sufficient, quality rest. The data also helped establish a link between caffeine intake and sleep disruption.

Does the App Require a Jawbone Tracker?

No, you don’t need a Jawbone UP or UP24 wristband to use the Up Coffee app. It works on its own to track your caffeine consumption and provide feedback on whether you’ve had too much. However, if you do own one of these devices, the app becomes more powerful. It can sync with the tracker’s sleep data to show you personalized insights—such as how your caffeine habits actually affect your rest. After tracking for 10 days, the app estimates that 100mg of caffeine delays your ability to fall asleep.

What’s the Caffeine Sleep Delay Finding?

According to Jawbone’s research, after 10 days of combined caffeine and sleep tracking, the app determines that consuming 100mg of caffeine can postpone your sleep. This insight helps users understand the real trade-off of that mid-afternoon coffee. While you might feel more alert in the moment, there’s a measurable impact on your ability to fall asleep later. The app doesn’t tell you to quit caffeine—it just gives you the data to make an informed choice.
