The most bizarre App I had to analyze: it's a mix between Foursquare, Facebook Places, Snapchat, and Find My, but taken to the extreme, to the point where privacy practically doesn't exist.

It's a kind of interactive map where you can see what your friends are doing in real time, if their battery is running low, how fast they are moving, how long they've been in a place, what music they are listening to and even play it from your phone. It also sends them notifications when you're nearby and has other equally invasive features. You have to watch this video to understand how crazy it is.

I told more about the App, why people now enjoy using it, and how it became trendy in my newsletter this week.
