## What is Caffeindiary?

Caffeindiary helps you log daily caffeine intake and understand how it may affect your sleep.

Record coffee, tea, energy drinks, bottled drinks, supplements, sweets, and custom drinks in just a few taps. The app estimates caffeine amount, remaining caffeine in your body, and bedtime impact based on your records.

Use it to spot patterns, manage evening caffeine, review sleep trends, and build a routine that works better for your body. Caffeindiary is designed for simple daily tracking, with JSON backup support and optional premium features for enhanced sleep analysis.
