One of those new apps which are really turning heads, Periscope remains the hottest app of 2016. This particular app works kind of like Snapchat but instead of posting pictures, this is completely dedicated to posting videos. You make a video live and it is on the feed for your followers to see for the next 24 hours. After that time period, it is gone for good. This is perfect for on the spot recording some events, or even broadcasting some sort of news.
