Have to say that I purchased this app a few years back to use on my iPad 3, but I soon found out that it didnt work so well on it, videos would play or I would get low frame rates and so on, especially 720p or 1080p mkv format
But now I am using an iPad pro and thus far this play just about everything I throw at it no problem, even dual audio files with multiple subtitle formats, something that I was not able to do before on my iPad 3
Im glad I decided to try this app again once I bought the iPad pro because now I am able to play files without having to re encode them to MP4s anymore!!
