HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (52 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Price and subscription42%

8 of the 1 and 2 star reviews.

★★★★★ Uncomfortable to read if they had a setting on the app to make text size bigger I'd pay for subscription but until this is created I'll pass
★★★★★ I saw the app advertised as free unlike Blinkist, so I downloaded and filled the opening survey, and then it said I had to pay money to do anything.
★★★★★ The app can't be used without their subscription!
Bugs, things not working21%

4 of the 1 and 2 star reviews.

★★★★★ Was great till app crashed and stopped working.
★★★★★ Concept is great when it works, but technical issues and very little support.
★★★★★ Also, there doesn't seem to be a way to access 10 free summaries in the free plan even though they claim you can (so I tried the pay plan and it still doesn't work).
Limits, credits, locked features21%

4 of the 1 and 2 star reviews.

★★★★★ I could've tolerated a semi-free approach with limited selection, but this was nothing free.
★★★★★ But no, I click on literally anything and it says I have to pay.
★★★★★ You have to pay for an app that's AI generated???
Login and account problems21%

4 of the 1 and 2 star reviews.

★★★★★ I never pay for an app unless I can verify that it does what I want.
★★★★★ I signed up for the monthly plan, but every time I try to read a summary it says I need to sign up again.
★★★★★ Okay so here goes… All I've had since signing up or attempting to sign up, is issue after issue.
Crashes and freezes16%

3 of the 1 and 2 star reviews.

★★★★★ Was great till app crashed and stopped working.
★★★★★ However, the app frequently crashes, thinks you don't have an account when you do, and there are a lot of books that aren't summarized yet.
★★★★★ Tried several times even reloading the app and it keeps crashing the first sentence into a book.
No customer support11%

2 of the 1 and 2 star reviews.

★★★★★ Concept is great when it works, but technical issues and very little support.
★★★★★ At this point I just want my $100 back, I don't care about this app anymore, here I am hoping to support this app, So brief & they have horrible customer service and the app doesn't work at all.
WHAT THEY ASK FOR
  • Also I stalk all my fav books that I read like authors character details & read the summaries if I forget what was said in a book series 🫶🏽 it would be cool if I could upload my good reads history as well 5★, Oct 13, 2025
  • Please give me my money back and don't erase my review. 1★, Sep 2, 2025

Why is it advertised as free or semi-free when you have to pay for everything? Use Sumreads instead!

I saw the app advertised as free unlike Blinkist, so I downloaded and filled the opening survey, and then it said I had to pay money to do anything. Not even one book was free. I could've tolerated a semi-free approach with limited selection, but this was nothing free. Was free it one point, but not now? If so, that's very rude. That's without getting into the low-quality AI summaries which would be tolerable if it was free, but since it isn't, I'm better off paying for the high-quality human-written summaries of Blinkist, or my current favorite, Uptime. Use the website Sumreads instead, actually free AI book summaries!
