i have premium and it used to work but now the videos play with a black screen with no audio. I've tried everything from extracting apk files to renaming files. Developer hasn't emailed me back. I'll be seeking a refund. update: judokai worked with me and found that it's my phone just being too old. they thoroughly investigated the issue and made me feel seen.

Great app.Although I still can't access most of the app because it has payment and I'm still a student so I'll wait until I can pay for this. Anyway awesome app nonetheless. Superb video presentations (although this is based on all the videos I can access but the others are probably just as good) and clear step-by-step guides that are easy to follow even for a beginner like me. I'll just practice the techniques that I can access and wait to pay the rest. Thank you for the great app. Good Day

amazing quality and lots of content even without premium. I'm just confused about the new lite app, it s not clear if I should buy premium or get the free lite app. a bit more explanation about the differences would be helpful.
