Three platforms, three experiences.

The full workspace.

The Mac version takes everything the platform offers: a key for anything you do often, panels that dock to any edge, float as windows of their own or pin, the Book Card and the browsers — authors, series, notes, journal, statistics — in windows of their own, drag-and-drop just about everywhere, and an island design borrowed from Apple’s System Settings.

• Table viewSortable columns, a layout remembered per tab, folders among the rows, an action row above the table
• Up to four columnsA wide window reads like a newspaper: two, three or four columns in Pages mode, the count following the font size
• Keyboard shortcutsFor everything: ⌘B to bookmark, ⌘F to search, ⌘G for the progress drawer, F2–F4 for panels, Space for quick preview
• Panels and docksEvery panel docks to any edge, floats or pins; layouts move them all at once; a double Esc opens the panel selector, a double F9 the settings navigator
• Custom library locationPoint the app at any folder on your Mac or an external drive
• Portable libraryThe whole library is one self-contained folder — copy it anywhere for a backup, or import a Calibre library as it is
• Browsers in windowsAuthors, series, notes & highlights, the reading journal and statistics open as library tabs or in windows of their own, beside the book

The version to use when you have a keyboard, a chair, and time.

The pocket reader.

The iPhone version is adapted, not stripped. Everything that earns its place on a small screen is here; the table view and the floating panels sit it out, because cramming them in would only make the app worse. In their place: full-screen reading with active corners, tiles instead of panels, native sheets — and the library’s tabs, browsers included, laid out for a phone.

• One-hand friendlyControls within thumb’s reach. Two page-turn layouts — top/bottom for one thumb or left/right for two — and a “Show tap zones” overlay that draws them onto the page so you never have to guess
• Native sheetsFolders, settings, filters, the browsers — sheets of the right height instead of separate windows
• Always full screenThe page takes the whole screen. Professional has two active corners — settings at the bottom-left, navigation tiles at the bottom-right; Comfort has one corner and one menu
• A bottom bar you assembleSession time, clock, battery and your position — a reading for every slot, in the style you pick, with a live preview
• The library on a phoneTabs as a history, the Authors, Journal and Notes browsers re-laid for the screen, rows that tighten as the list grows, cards two to four across
• Gesture navigationEdge swipes, swipe-to-dismiss sheets. iOS the way iOS should work
• Sink and CardsThe phone’s page turns — one card the screen wide — beside Slide
