Can I sleep tonight? Track your caffeine and find out.
Caffeine Curve is a simple iPhone app that logs your coffee, tea, and energy drinks, plots how the caffeine decays in your body, and tells you exactly when you'll be clear enough to sleep.
Questions, bug reports, or feature ideas? Email jalieb0812@gmail.com and I'll get back to you as soon as I can.
Caffeine Curve collects no data. Everything you log stays on your device. Read the full privacy policy.
