How many tweets you make? How many tracks you listen to? How is this data going to help you improve your life? Tracking your sleep is one thing. But most of this is just noise. The name Exist is creepy. As if, you don't truly exist until you can pigeonhole yourself into a couple of statistics. I swear, everyone here is mind blind.
I agree that tweets and tracks probably won’t help you notice any useful patterns. But I don’t see the name Exist as creepy. I interpret it rather as a way of saying that this is very passive software, and all you have to do to use it is to exist normally, as if it’s not there. Like existence is the context of this software, not the product they are selling.
