Scorp - The Turkish Vines
If you are learning Turkish, you should take a look at Scorp.
Basically, if you already know "Vines", you will get used to Scorp pretty fast. It last max. 15 seconds and you can either talk about something serious, funny or do pranks and film it and publish it. You can do it in English but also in Turkish. You will be immersed in Turkish videos and I think that the people who are learning Turkish should publish their videos in Turkish.
Download it on Android (The app will be only in Turkish) or IOS (You can switch the platform in English)
