Good app, one problem.

Purchased the full course for a little over $20 and now it wants me to buy it again? I haven’t even gotten to watch one video. This is ridiculous. I think the content is good because i’ve watched the free video and I wanted to watch the rest but now i’m 20 dollars short and can not watch the video. I will change my review if this is fixed however.

EDIT: Okay so it has been fixed! I am really happy this was solved within the same day. it did cause me a bit of stress though haha. I’ve seen this happen to other reviewers and i’m not sure if they were all able to get it fixed. I am now fully pleased with this app.

Content great, app needs polish

The target size of the full screen button is ridiculously small, I have to press it 10x to toggle full screen. There is no auto full screen on landscape rotate, rotating the phone 180 while on full screen doesn’t rotate the video orientation.

There are 10-30 second black screen silences at the end of some videos. When a video is done I can’t easily close it to get the screen real estate back to scroll through the list easier.

Top level video categories are not expand/collapsible, given the number of sub-entries this makes discerning the layout of the hierarchy difficult.

The app has no feedback submission form.

The app is okay but a more experienced UI designer needs to take a look at it.

Charging me again!

Before your update I had already bought most of the videos and was able to watch them full length. Now, for the same videos, I can only see a few seconds of each and they want me to purchase them all over again! What kind of racket are you running here? I enjoyed this app until you started this mess. Either you fix this or the app gets deleted.

January 27, 2020 I apologize for my complaint that I am being charged all over again for videos that I had previously purchased. Apparently I forgot that I must enter my password under the “user” heading to access my full length videos. Seems everything is fine now.
