User reviews

Great app for tracking caffeine

The app is very minimal and does exactly what it needs to do

wonderful!

interface is sublime + genuinely very helpful!

Good effort, but missing key feature

The idea and interface are gorgeous… But there’s no way to alter the half-life and indicate with you or a slow metabolizer or a fast metabolizer and that is absolutely critical!

Love it

Really well made app, actually useful for tracking my caffeine usage.

Love it

The app is perfect for tracking my caffeine intake and seeing how it affects my sleep. I love that it estimates my caffeine level at bedtime, so I know exactly when to have my last cup.
