Old Solar: A Modern Reader

Old Solar is an ebook reader, PDF reader, and comic and manga reader in one app. Open EPUB books, PDF documents, CBZ, CBR and CB7 comics, image folders, and scanned books, and read them all with the same calm, consistent reader. It works offline, needs no account, and has no ads.

Bring your own files and read them the way you like: on a dark theme at night, in a scrolling strip for webtoons, right to left for manga, or read aloud while you rest your eyes.
