## Sumi Book Description
Sumi is a beautifully crafted, native reader for the manga and comics you already own or have the right to read.

Sumi comes empty by design: no catalog, no content, no built-in sources — you decide what to read. Import your own files, connect your own server, or add a source by pasting the address of a site you are entitled to access. Sumi brings the reading; the library is yours.

A READER, NOT A LIBRARY
• Your own .cbz, .cbr, .zip, .pdf and .epub files, from the Files app, AirDrop or Mail
• Your own Komga or Suwayomi server
• Your own source: paste a site's address, or share a page from Safari — no content or site is included: Sumi recognizes common site software as soon as you paste an address
• "Test this source" shows which step fails, and Sumi notices when a site moves

DESIGNED FOR READING
• Ink, dark, and Paper, light: two themes made for long sessions
• Paged or vertical-scroll reading, right to left for manga, and Guided View, panel by panel
• Resume: the titles you're reading at the top of your Library, back to the exact page
• An end-of-chapter page, bookmarks, and tap zones your way
• Rate titles from one to five seals and keep a private note
• On iPad, Sumi follows the size of its window, and the keyboard turns the pages
• Free backup and restore of your whole collection

THE NOTEBOOK
Four tabs: Library, Browse, Notebook and Settings. The Notebook keeps track of your reading, like the seal books travellers have stamped from temple to temple:
• Twenty-eight ink seals to earn by reading, a few of them secret
• A forgiving daily streak, a weekly goal, and challenges for the month
• The ink calendar, your ex libris and the year's Almanac, to share as pictures
• "What to read tonight?": the omikuji draws a title from your pile
• No account, no leaderboard: it all stays yours, and "Plain reading" hides the play when you just want to read

BEYOND THE APP
• The Resume reading widget takes you back to the right page
• Siri, Shortcuts, Spotlight search and quick actions on the app icon

THE FINE PRESS (PREMIUM)
• Offline downloads, from your Komga or Suwayomi server too, with predictive download and storage management
• iCloud sync across iPhone and iPad
• New chapters in the background, the visual selector and Change source
• Continuous reading, on to the next chapter by itself, two-page spreads, color filters, page previews
• Detailed statistics, unlimited history, the whole year in the ink calendar, the Almanac month by month, the seals of the seasons
• Streak and seal widgets, and the Papier, Hanko and Sakura app icons
• Incognito mode, App Lock with Face ID, Touch ID or a passcode, the Sakura theme and an automatic theme
Seals, the streak, the weekly goal, the omikuji and the Resume reading widget stay free.
