5★I really enjoyed using this app and have moved to the premium version. I enjoy reading but whenever I wanted to get busy, I'd just switch to listening until I could go back to reading. I switched to premium because I wanted to be able to do other things with my phone while listening and though they're AI voices doing the reading, they're frankly doing a better job than many narrators out there, lol. So, yes, I recommend and am happy with my premium purchase too.

5★I really enjoy this AI Audio reader. I like to read and listen to my books but I can't always afford the audible. This is an awesome Plan B. I immediately purchased the premium option without question. Premium is a one-time charge and it's under $15. You have lots of AI voices that you can choose from. Including Australian, United Kingdom, English and more. I highly recommend this app for people that like things read to them; for whatever reason!

5★Currently one of the least annoying apps on the store. No ads (as of 19-02-2026), easily ignorable premium tier, decent free features, and can handle plenty of the major file formats. It's not the only Reader around but it works great for me. I would like to have more control over where the app defaults to. I'll sometimes be looking for a new book I've bought and downloaded and it obviously isn't in the "reading now" section.

5★The app is just perfect. It makes reading books very convenient and joyful. Right Way I put my books in a folder and loaded to the app. In merely seconds I've got my own library and it is sorted and arranged in a very elegant way, the thumbnail of the book and its title, and a few option below it. I can make my collections quite easily. I can translate words in a second, I can use dictionary as well, add quotes, bookmarks, and many other feature. I have totally not a single complaint. thanks alo

5★so far so good. love being able to get so much use of this app. I like the feature next to 'read'. I think it's a speaker or sound icon. that is a great resource in its self, when you don't wanna read. I hope this is helpful. no stress premium. these guys are dope, support them. also I love having the ability to change the background color. doesn't work with older books. it holds your place too! I could continue...
