Track your Caffeine Level throughout the day

I drink two or three cups of coffee each morning during breakfast and afterwards when I start to work. I do that mainly because I like to drink it, especially in Winter when it is cold outside, and not so much for the other benefits that it provides, but also to get inspiration for my coffee blog.

While I do not notice much of a benefit in regards to "waking up faster", I noticed that when I drink coffee too late in the day, that I sometimes have troubles falling asleep.

That's the core reason why I do not drink beverages that contain caffeine in the second half of the day.

If you consume a lot of coffee or other drinks that contain caffeine, it may be of interest to you to keep track of your caffeine level throughout the day.

Track your caffeine level

While you could do those calculations in memory, or on paper, you can also use an app like Caffeine Tracker for that which does all that for you.

Here is how it works: whenever you drink or eat something with caffeine, you add the information to the application. It ships with four drinks, Coffee, Espresso, Soda and Tea, and options to add others to it easily. If you prefer Mocha, you can easily add it to the app.

Before you get started, you may need to make changes in the preferences as metabolism depends on factors such as your weight or whether you are pregnant.

Here you can also modify the default unit size from Ounces to Milliliters, and enable or disable the apps' notification feature.

Caffeine Tracker can notify you if your caffeine level rises above or drops below a certain level.

Adding a new drink is easy. All you have to do is pick one of the presets that shipped with the app or that you have added to it, type the size of it, and the date and time you have consumed it.

All drinks that you add this way are displayed in the program's main interface. Here you see them listed separately based on the caffeine level, and an overall level that is an accumulation of the caffeine of all drinks.

The app does not provide you with any information about the current caffeine level. Generally speaking, about 200mg to 300mg per day is not harmful to most adults.

The application itself is free, but displays ads at the bottom of the screen. A paid version of Caffeine Tracker is available which does away with the ads, and introduces new features such as a history and projecting chart, improved drink input, and editable drinks.


If you need to pay attention to your caffeine intake, or simply want to monitor it for a period of time, then you may want to try out Caffeine Tracker as it helps you do so easily.

    (Shit, you don’t want to check subscribe before submitting your comment. If you do, the comment ceases to exist.)

    Without a caffeine assay device to go along with this it is about useless. There is enough difference between a cup of dark roast (low to negligible) and a cup of normal roast (high but variable) to make the app just about information free. I’m sure they know this so the paid version is a straight up scam.

    Caffeine shortens life, alcohol increases it

    Researchers have discovered that caffeine can shorten life expectancy, while alcohol can increase it….

    Take your Irish coffee with double dose of alcohol :-)

      Well, caffeine and alcohol affect yeast telomeres in opposite ways, according to the research article linked. However, daily intake of anything more than 10 to 20 grams of alcohol — 1 to 2 “drinks” — will, on average, decrease lifespan in humans. Since drinkers develop tolerance for the intoxicating effects of alcohol, it’s very common for 10 grams of alcohol daily to become, in a few years, 25 grams daily (a pint of Guinness), then 50 grams (about a half-bottle of wine), etc. More than a token amount of alcohol can damage your liver, pancreas, brain, and heart (although a small amount of alcohol reduces chances of coronary heart disease, larger amounts increase chances of arrythmia, cardiomyopathy, and hypertension). Watch out for the “alcohol is healthy” myth! ;)

    That’s a useful app.

    “Check if you are pregnant.” (Should be “Checks if you are pregnant.”)
    I’m not sure how that works. Do you have to pee on it?

    (If no one got it, this was meant to be ironic, though the app has its uses.)
