Read full description

Organize your PDFs, set custom covers, and choose from several theme colors and icons, for a pleasant reading experience just the way you want it. • Create folders and folder groups to keep your PDFs organized however you prefer. Rename and rearrange things as the mood takes you. Name every single book and folder the same thing, if you really want to! (I don’t recommend doing that, but nonetheless, that’s the sort of awesome power that you wield if you use BookFolder.) • Set custom cover images for every book (or stick with a book’s default cover, of course). Your library will look the way that you want it to! (And the underlying files remain pristine, so if you begin to regret choosing a photo of your cat for every book in your collection, you can always restore the originals and no one will know. Except your cat, who is judging you now.) • Get wild on an iPad with split-screen multitasking support. Read two books at once (or the same book twice)! If that’s something that you want to do. • Swap between five theme colors, for an interface that works best for you. (Dark Mode support, too, of course!) • Choose from a dozen icons, from solid colors to subdued platinum to a retro rainbow look, to fit your mood and to ensure a harmonious home screen layout with your other apps. (I’m not the only one who arranges my icons by color and design… am I?) • You can use it to actually read the PDFs, too, of course. Mustn’t forget that part. • Plus bookmarks, searching, and table-of-contents support, as one would expect. • Also, it’s free, no in-app purchases, no tracking… just a nice PDF reader and library manager. I hope that you’ll enjoy it!

Read full description

Find out how long it will take to finish your book. Simply log your reading sessions. Reading Time is built for readers who care about finishing important books, but read in short, irregular sessions. Instead of pages, streak pressure, or generic estimates, it shows the remaining effort for each book based on how you actually read. This lets you decide, realistically, whether a book fits into your life right now. Start reading and stop when you’re done. Reading Time learns from your sessions and shows how much effort is left for each book at your own pace. If you’ve ever thought “I want to read this, but I don’t know if I have time,” or found yourself starting books and never finishing them, or felt put off by apps that expect daily consistency, Reading Time was made for you.
