Learning the fun and easy way

Koober’s really picked out some fantastic books to summarize and the summarizations are very easy to understand! I also love how they quiz you at the end to reinforce/clarify what you take in. And the option to speed up the readings! That was genius! The only issues I’ve encountered was in the quiz sections - receiving a blank page with selection buttons for one of the questions (I restarted the app - still the same problem. Had to randomly select one of the buttons and got the “answer” wrong.) and answers being flipped (true/false question - false on top, true on bottom. Clicked false but got told my answer was wrong - “the correct answer is false.” If Koober could clean up their quizzes a bit, that would be great and earn them 5 stars from me.

Honestly I had the app for 2 days and I’m loving it. I think you guys need better marketing, better ads targeting entrepreneurs because this would be a great tool. The books are actual books that can you find in a library so it’s not like they write them them for you. Also, I feel like you guys would have more clients, and make more money if you would drop your price a bit more. I would definitely pay around 5.99 to 6.99 monthly. And don’t try to be like others apps putting the annual cost first. This is a great app actually so don’t get that same reviews as “oh they charged me so much and I didn’t even know” keep it up guys this is great.
1) drop the prince
2) don’t be like the others apps (scam)
3) more content
4) better advertisement
5) better targeting

Love the App but...

I use the app everyday. My schedule is usually one Koob during a workout. I’ve even purchased some books based on my listening to get a deeper dive into the topic.
The quizzes are fun, though a bit easy, but they act like little checks to make sure you were listening.

The only complaint, and I’m not sure this is something the developers can handle, is that I wish there was a way to filter out the content with leftist propaganda. We get he evangelism all day. For now my work around is just skipping recent Ted talks, because no matter the topic it seems the leftist religion is the one true way.
