Caffinity: Caffeine Tracker

Caffeine intake & sleep impact in real time. Predict your crash, beat insomnia, and finally drink coffee without wrecking tonight's bedtime.

Caffinity is the caffeine intake monitor that finally tells you when your coffee stops affecting your sleep. Track every cup. Watch your real-time mg level rise and fade. Predict your crash before it hits — and stop drinking past your bedtime.

Most coffee tracker apps just count cups. Caffinity uses real caffeine half-life science — your weight, sensitivity, and last dose — to show you exactly how much caffeine is still active in your body, minute by minute.

If you've ever lay in bed at 1 AM wondering whether your afternoon cold brew is keeping you up, Caffinity is the app you've been waiting for.
