Love this post. Mondly is also good. I have tried it, but only gripe with it, has only portrait mode. I didn't know about language tags, thanks for that too. I should try the player app. It's a good replacement for when we used to use KM player around here to make subtitles work. and yes they worked but then the installer inaccessibly died. I have used all these tools, but seeing someone else also having use of these, and knowing I am doing something right, is a good thing. I hope people will find it useful. Double thumbs up!
