This is the most fully featured ebook reader I've found! Lets you use word "replacements" for tts that aren't shown on text to correct pronunciations. Also lets you correct words visibly. TTS is the best I've seen, though it doesn't have its own voices (samsung sounds more natural than google), and I wish it could use the speechify AI ones. Bookmark sync is great, allowing me to read on my kindle and phone and keep my place. I have it hooked up to my Calibre Library and it syncs metadata well.

Let me start off. This is a great app when it works like it should. I have 3 phones and for some reason it's only syncing eith Google drive on my S24 and not my other 2 devices which are samsung a 15s they are only used for wifi purposes mainly to read books it's not working for them and I really need it too. I love to read, and I love books, and I need and desire for all these books of mine to sync so I can have access to them from I absolutely love and have been using for years.

There are 2 serious long-term bugs with this program. It has been a long time since there was an upgrade but these bugs are being worked on. 1. The program will often forget where you left off reading the book. You can work around the bug by remembering to leave a quick bookmark. Irritating when you don't get the chance to leave the bookmark but it is workable. 2. Will sometimes fail to render a page with an error message. You can work around it by going back 2 pages and then forwarding it to where the error occurred. These bugs are significant but not fatal. Even with these bugs this is the best ebook reader. Hopefully these bugs will be fixed before some other app steps up and surpasses the functionality of LibreraPro.
