What is Clarity?

Clarity is a caffeine and focus tracking app designed exclusively for iPhone. Originally built as a simple caffeine logger, it has evolved into a performance tool that helps you use caffeine more deliberately. The app tracks your intake, visualizes caffeine’s half-life throughout the day, and uses on-device AI—called Clarity Intelligence—to deliver tailored insights. The more you log, the smarter the app becomes, offering personalized guidance on how caffeine affects your sleep, energy, and focus.

Who it's for

• Casual coffee drinkers who want to understand why their afternoon coffee disrupts sleep and how to time their intake better.
• Athletes and fitness-minded users who need to monitor caffeine’s impact on recovery, sleep quality, and training performance.
• Productivity-focused individuals who rely on caffeine for focus and want to avoid energy crashes by using it more strategically.

Key features

Fast caffeine logging & visualization

Log your coffee or energy drink in seconds. Clarity instantly shows how caffeine accumulates in your system and how its half-life extends into your evening, helping you connect your 3PM crash to that morning latte.

Caffeine half-life tracking & prediction

The app calculates and predicts how long caffeine stays active in your body. This lets you see exactly when your caffeine levels will drop, so you can plan your last cup without compromising sleep.

Verified brands and products

Clarity includes a Discover section with verified brands like Contact Coffee, Arctic Coffee, and A1 Physique. You can log with confidence using accurate caffeine values directly from the source, making tracking more reliable than generic databases.

What stands out

Clarity is the only caffeine tracker with verified brands in-app, helping you log with more confidence and accuracy.

This unique feature sets Clarity apart from generic trackers. Instead of guessing caffeine content, you get verified values from real brands. Combined with on-device AI that learns your habits, the app becomes more useful over time—turning a simple log into a personalized performance coach.
