I've had this app since 2018 and have used it to read ever since then The recent update requests the app to have access to all files, and read, modify and delete any files on your phone without notifying you. The app is good for reading but not worth it in the slightest for the cost of everything on my phone. I'm unsure why the creators wanted access to all files, and why a single file can't be selected instead, but I've downloaded an alternative app and will be uninstalling this shortly.

Hi, if you've used it for a while, you likely already gave it a storage permission originally. Android then made it so apps can't use that one anymore, and have to use this new one if you want general access. This one might be more broad though. I may consider allowing a scoped directory on new Android, but I think users like ease of auto detect.

As an aspiring writer, i often use the notes section to keep track of particular bits of prose that I like. However to access these notes, I have to go to the book that the notes are on. Please add a "notebook" feature that allows me to look at every note i have ever made, in all of my books at once, as well as search through all of them via key words, and filter them to specific colours and books. If you guys do this i will definitely rate the app 5 stars its pretty much perfect anyway.

Best thing that has ever happened to me. Lithium lets me to store so many books and in my opinion mimics the whole experience of reading physical novels. You can carry dozens of books with you anywhere you go and you can control things like colours, brightness, text size etc. to minimise the effect on your eyes that all types of reading can bring you. The format is quite organised and pretty and the app takes up very little storage. One thing I hope they do is allow you to read pdfs as well.
