Caffeine Tracker

It would be cool if you could set a time when you drank something some time ago. The icon is funny but an icon in flat design that represents the caffeine molecule would be cool too. Also: shouldn't the same amount of caffeine be absorbed into the blood more slowly if you consume it through a larger drink (more ml)? Also maybe it would be nice to adjust your metabolism so that the same amount of caffeine stays in the blood longer or shorter depending on the person.

Body weight is important in coffee consumption and the ability to add entries further back in time would prevent the need to pull out your phone directly after a relaxing drink.

Thank you for making this. Simple to use and no unnecessary sign ups or permissions. My only suggestion would be to add the ability to change the time when inputting a drink. Like if you had a coffee 30 mins ago, you could change it to reflect that.

Half life of caffeine is about 6 hours. I took 100mg and 2 hours later it said I have 15mg left in my body.

Had the app for 5min and deleted because it didnt have the option to input what time you consumed the caffeine.

Seems to work, but you can't adjust for sex and weight. A 6'5 male and 5'1 female aren't going to be the same results.

No stupid permissions and awesome functionality with great UI.

Limited abilities. Can't add drinks that were consumed earlier in the day.

Actually models estimated blood caffeine levels

Selection of caffeinated beverages is limited

Needs timed entry and entry deletion. Plus charts and more stats would be great. I would pay for this if it had no ads and charts for premium.

Doesn't install on Android 5.1

Rated 5/5 based on this alone. Interesting app otherwise.

This is a must for caffeine junkys like Me.

keep up the good work

Extremely useful!!!
