3/5Thankful but annoyed…
Just like the last one so I am not gonna complain about the ads, although it would be nice to have a lifetime payment to get rid of ads… if you still want to keep that revenue stream you could make the points actually do something to incentivize watching the ads for them. But hey, I get it. What I don’t get is the constant crashes, all of the sudden the app has been constantly crashing, it even crashes during ads so when I get back in I see another ad immediately when I try to read. Please fix.

1/5Has potential but also critical limiting issues
OK, the look and feel of this app is pretty nice. The reading experience is pretty good maybe even good but this app constantly closes. I’ve tried lots of different settings to see if maybe there was some setting. They had a bug no matter what the app just randomly closes every couple minutes. This is obviously detrimental to reading immersion. I will not use it. Additionally, I just wanna add on their website it’s always down for 30 minutes of maintenance every day and they tell you to go use the app. This feels extremely manipulative obviously websites go down for maintenance but every day for 30 minutes and they tell you to go use the app.? This is very suspicious and not a good decision.

1/5To the creators.
While this app has potential and is easy to use. The vulgar amount of crashing and randomly pop up ads is very poorly done. First fix the crashing issue. If you can’t keep the app open then it’s wasting space. Second I understand wanting revenue but interrupting my chapter in the middle is a very disrespectful way of going about it. Move the adds to the beginning of the chapter so that you get your revenue and the readers can watch it or skip it then enjoy their chapter until the following one. I am removing this app due to it being unusable and stressful. I will check back in several months to see if they read reviews and actually make the changes needed to make this app better.

1/5Crashes and Too many Ads
This app is one of the worst I’ve ever used. I only downloaded it because the website was down (which is also annoying with ads I can’t even click to the next chapter without 2-5 opening new tabs) the app crashes about every 3-4 pages or there is an ad. Super annoying and the book I’m trying to read has ALOT of chapters so I may just have to find it elsewhere.

5/5Great app
I see many reviews that mentioned a terrible bug that crashed the app frequently. As of October 2025, I can confirm this bug has been patched! My favorite thing about this app is that it remembers exactly where you left off reading. If I was halfway through a chapter, when I reopen the app it opens at that halfway point instead of the top of the chapter. Great app from all I can see
