React Native, you get nicer performance and the interaction is a bit more slick, and we can reuse a lot of our Typescript code from languageReactor.com.
First we’d try do TurtleTube, our dictionary with examples, and a flashcards/example sentences mashup thing (Kirian is prototyping it now, it will appear soon on the languageReactor site). Netflix on mobile would be really tough, would need to reimplement big parts of Netflix’s player stack (I mean, kodi does it), I don’t thing that will happen. 
But, we will soon expand TurtleTube to support playing entire channels, perhaps soon a general Youtube search feature.
If anyone is skilled with React Native and got some time on your hands, you can send an email to dioco@dioco.io , or, if you aren’t getting a response, give me a call on +359 879 three four zero 1 9 ‘IV’, anytime 11am to 11pm CET, I’ll be happy to hear from you.
