A decent app with a few quirks

Most of the time, it’s a good app. However, there are some design choices and bugs that make the user experience really unpleasant.


When I finish downloading a set of videos, for example, the “Introduction to Go Programming”, the playback progress for every video is close to the end. So if I start a lesson, I have to manually slide backward to the very beginning. And when I finish, because the following videos are all close to “finished”, it would just jump through all of them because the autoplay option is set to true.
On the web version, I can clearly see that I have not started the following lessons. However, in the app, it’s not the case. I have to manually catch and pause the video before it jumps to the next one.

Unpleasant design:

As for readings, I believe most people grow to read books page by page, left to right or right to left. However, this app forces to scroll up and down, with no pagination. That’s rather unnatural and annoying. I mean, we are not scrolling a webpage with a mouse wheel; We are using our finger tip.

No typeface selection is a bummer.

Font size is still not as large as I would like even at its largest. Readable, but not so comfortably in a distance. I need to find where I left off for a second or two, which is not so pleasant.

App not starting after the last update

Continuously frustrating issues using this app. After the last update, again, the app fails to open. It’s stuck at the initial gray screen with the logo in the center. I suppose I will have to uninstall it and re-download all my offline content, again. There is no way this app can have a legitimate 4.6 reviews rating at the current sub-mediocre quality, features, and usability.
Using the browser on my tablet to access the content is not much better, I can not get rid of the message to use the app instead and I can not use offline content.
Until I find a monthly subscription alternative for technical content I guess I’m stuck with this horrible way of consuming and finding materials, and I guess the developer is well aware of the monopoly - hence the low quality and the lack of innovation demonstrated by the app.

Version 2.2.3 crashes on iPad Pro

The app was running fairly well and had Improved substantially, but the latest version (2.2.3) is now crashing at start 100% of the time on my iPad Pro. I love the Safari content, but the iOS app has been frustrating. Updates sometimes run well or adequately, but some updates are painfully slow to start or navigate. This version is unusable. I tried force quitting and rebooting my iPad, but it did not help with this latest problem. I may try to uninstall and reinstall the app again, but I would rather not be forced to download my content again.

Developer Response ,

I'm sorry to hear the app is crashing on you. Please reach out to us at and we will work with you to get it resolved. I understand that it's inconvenient to have to download content again, but uninstalling and reinstalling is certainly a reasonable thing to try.
