iOS app - leran languages via watching YouTube videos. Could you try, please?

Hello everyone,
Please don’t consider this an advertisement, it’s just a friendly request. The thing is that my friend and I have recently made an iOS app dedicated to the learning of foreign languages via watching YouTube videos with subtitles. Each word is translatable and afterwards the app provides you with videos where those new words are present once again. So, if you have any iOS device, wouldn’t you be so kind to try it and share your opinion? It’s just been released and I’m really anxious to know if it sucks or not.

Download on the App Store: (or just search for “Langvideo” in your App Store app)

Short demo, just showing how it works:
