With the rise of wearable technology, it is only inevitable that there is now an increasing amounts of data you can keep track of. The Jawbone Coffee App allows you to enter, you guessed it, your coffee intake. Though you do have to manually enter the information on the app every time you drink a coffee, the app does simplify this by having pre-programmed options from two of the more popular coffee chains, both Starbucks and Dunkin Donuts. So, after you stop off at Starbucks for your morning Americano, all you have to do is choose 'Americano' and pick a size from the menu. It will also save your most recent inputs, so if you have a routine drink everyday there's no need to go through the menu again, it will be right on top. What's the point? The app knows precisely how much caffeine is in that cup you just had. Next time you go to the doctor, and once more data points are recorded, your doctor will have a substantial amount of personal data to go over. And why not add caffeine to the analysis?
The interface could use some improvement, but the overall idea is there. This is another example of the push for the 'quantified self' that I've mentioned in previous posts.
You can also see a graph of your sleep readiness, which Jawbone calculates based on caffeine intake and body statistics such as height, weight, and level of reaction to caffeine. Sometimes I'll test this by entering a coffee into the app and seeing what time I'll be sleep ready. It can help someone gain awareness about how long the caffeine will be in their system for. Perhaps you will now be able to correlate with certainty that your sleeping pattern is affected by your caffeine intake. Give this app a whirl if that is something that sounds interesting to you.
