Questions
Before you choose.
Short answers about versions, cost, accounts and moving your books.
Which version of DeltaScroll should I use?
Use the Android app on a phone or tablet, the Windows app on a PC, and the web reader on any other computer or when you would rather not install anything. They all read the same books and share the same backup file.
Is DeltaScroll free?
Yes. DeltaScroll is free to use on Android, Windows and the web, with no ads and no account. If it is useful to you, you can support its development.
Do I need an account?
No. Your books and reading progress are stored on your device. Google Drive backup is there if you want it, and it only connects when you turn it on.
Can I move my library from one device to another?
Yes. Create a backup on one device, then restore it on another. One file carries your books, reading positions, shelves, favourites, highlights and notes.
Which files can DeltaScroll open?
EPUB books open directly. PDF and DOCX files are converted into readable books on your device, so nothing is uploaded.
Is there an iPhone or iPad version?
Not yet. An iOS version is planned. In the meantime, you can try the web reader in the browser on your iPhone or iPad.
