學外語

Trying to use this app to read books in new languages. I am taking advantage of the highlight to read aloud function. Having each paragraph auto translated is very helpful. However, I wish that there was a way to have the TTS play at the same time as the translation. I want to hit a word and hear the pronunciation and see the translation at the same time. This would save me so much time. Edit: I decided since the app is open source, I can just add the feature myself. And I did! 5/5 stars!

四台裝置，四個系統

Syncing across 4 devices with 4 different OS's. Initially meant as a way to keep reading on my X3 after purchasing a Viwoods Aipaper Reader C but it has now evolved into an ecosystem 😄 … Via this plugin the X3 with Crosspoint is synced with Readest. Meaning I can read my book on the X3 on then on the Viwoods (Android), iPhone (IOS) and Macbook (OSX) with the dedicated app or the webinterface.

ADHD 也能讀下去

… As someone who struggles to read due to ADHD the app’s text to speech feature is an absolute lifesaver! I can listen to a book while getting stuff done or playing games. While the TTS voices aren’t expressive like audiobooks they don’t sound robotic either and you can even choose from a variety of different speeds for it to read it to you. … I have been using this app daily and I believe it deserves a lot more praise! …

放下社群媒體，拿起書

Best free reading app ever. Finally replaced my dopamine spikes from social media with reading. Synchronization is very easy to setup and costs nothing to have up to 500 MB synchronized. If you ever need more there are subscription and even lifetime options that are both priced incredibly generously. Thank you devs! You are the best!!!

什麼都能自己調

I want to control everything about my reading experience, down to whether or not the text is hyphenated when it is wrapped to the next line, the line spacing, and information at the bottom of my screen. And this somehow does all of this, and more, like importing font files and dictionary files! Finally, it does not randomly offload books to the cloud, which Apple Books does every single time.

多裝置接著讀

Hands down one of the best readers I've used over the years. It's a no brainer if you like to read across multiple devices; I use it to sync my progress between my phone, tablet, and e-ink reader. Started using it for novels and then it became my reader of choice for academic and reference books too, it's just too comfortable. I'm not interested in any of the optional AI features so I purchased some lifetime storage to support the project instead.

KOReader 同步

I love using alternate software on my Kindle. The only stock feature I missed was the ability to pick up where I left off on my phone later on. With the new update, this app finally gives back the same functionality. It took me some trial and error to get matching files to the app, but now it works without a second thought. I can’t overstate my gratitude to the dev team for making such great software—the fact that its open source is even better. …
