Peek is a live streaming app that lets you go live anyplace, anytime. The unique thing about Peek is it lets you go live and not let random people know about it. In other words, you could live stream and choose who can view your streaming. For example, if you want to live stream to a class privately, Peek helps you do so. This makes the conversations more intuitive or engaging. Unfortunately, the tool works only with Facebook. This means if you don’t have a Facebook account and do not intend to create one, you cannot use this app.
