So, This weeks app has to be Periscope (made by twitter), the latest live video streaming social network that is going viral and recently got featured by Apple in the App Store. The immediate contender of Periscope has to be Meerkat, another live video streaming service. Now back to Periscope, The app is pretty polished and with minimalistic design. The main feature that distinguishes it from Meerkat is that it saves your streams for 24 hours in your profile.People can click to join in your live broadcast and can comment or like to show their opinion. Overall the app is pretty good, and can be fun to see happenings from all around the world.
