About this app

Enter your caffeine usage to see an estimate of how much caffeine will still be in your system around bed time!

Have more than one coffee (or any other caffeine containing beverage) a day?
You can add that too.

Also check to see if caffeine maybe carrying over to the next day and stacking up more than you'd think!
Calculate the half life of your coffee (caffeine) use, to help sleep with habits
