However, I have noticed that I can go about half a page before TTS will skip over dialogue on pdf files. Sometimes it’s very short. Skipping over a sentence or two. Other times it will skip a paragraph or half a page. It’s infuriatingly annoying that I have to basically stop and restart the TTS. At first, I thought I was hearing things until I read along with it and saw it happened. If the TTS wasn’t skipping, I’d give this a higher rating. Seems like I don’t have this problem if I am using TTS on an e-book file. Seems to only not work properly if I am using it on a pdf article or something. ### 5/5 — WOW *2026-08-10, version 0.11.20* This is the app I've been looking for years. I have tried every single e-reader app out there and none of them did what I wanted conpletely. Finally I got Readest due to getting a Kobo/Koreader. I genuinely wish I would have found it sooner because WOW. Just wow. It's literally the perfect program and I always skipped over it because low reviews. So here I am, giving it my 5 stars. It deserves 10. That speed reading mode? Bro....amazing. When I get this job I will buy buying the app outright in support. ### 5/5 — мечты сбываются *2026-08-09* я нашла тебя!❤️ читалка-комбайн, Аква настроек внешнего вида, TTS годный. ### 5/5 — 屏幕左侧滑动亮度调节问题 *2026-08-06* 滑动翻页很容易触发亮度调节 是不是考虑优化一下呢 **Developer response:** 翻页一般是左右滑动吧，为什么会上下滑动触发亮度调节呢 ### 5/5 — 好用的，但是不知道为什么今天一直灰屏 *2026-08-04* 好用的，但是不知道为什么今天一直灰屏 **Developer response:** 重启一下手机试试 ### 5/5 — 增加阅读时长功能 *2026-07-30* 能不能增加一个阅读时长的功能 ### 4/5 — 好像出bug了… *2026-07-29* 总体使用体验是相当不错的，但是前几天更新后好像无法正常使用了，点开后显示完logo 后续就是灰屏了 ### 5/5 — Top *2026-07-29* One of the most free e-reader. Just a little bug: in the very nice multi book viewer, when we put the app in background and we come back all books are closed. ## Frequently asked questions about Readest ### What does Readest do?
