Onto the cover screen
Fold the phone and the page you were reading continues as a single page on the outside.
Foldable phones
Read the book the way it was printed. Now it opens like one.
Unfold an iPhone Duo or a Galaxy Z Fold and Tomelet lays out facing pages either side of the fold, the crease as the spine. Close the phone mid-sentence and the sentence is waiting on the cover screen.
Part of the free reader. Most books open as a spread on their own.
Two pages, one crease
A spread, not a stretched phone screen.
On the inner display Tomelet shows two pages side by side, paired the way a printed book pairs them: the first page alone, then two at a time. The fold sits in the gutter, where a book has its spine.
- The fold is the spineThe two pages meet at the fold, where a printed book is bound.
- The book’s own directionRight-to-left and vertical Japanese books start on the right-hand page and turn the other way.
- Every kind of bookEPUB and other reflowable books, fixed-layout EPUB and comics open as spreads. For a PDF, choose Facing pages in Page layout.
- Your call, per bookPage spread offers Automatic, Single page or Facing pages for each book on this device; a PDF keeps its own Page layout choice.
Fold and unfold
Close it mid-sentence. The sentence waits.
Folding the phone changes the screen, not the book. Nothing reopens and nothing jumps.
Back to the spread
Unfold it and the same place opens as two pages again.
Marks stay put
Highlights, notes and pen ink keep their place on the words through every fold.
Mid-task is fine
An open toolbar or a note you’re typing is still there after the screen changes.
Half open, on a table, side by side
Held like a book
On an Android foldable that reports it is half open, you keep one page on each side of the fold and the reading controls stay off the crease.
Set on a table
When an Android foldable reports that it is half open on a table, the page moves to the upper half and the reading controls to the lower half.
Sharing the screen
Next to another app, Tomelet shows one page and makes no guess about where the fold is.
Where it has been tested
Automated tests cover facing pages on the iPhone Duo simulator (iOS 27.1), and facing pages, fold and unfold and the half-open postures on Google’s Pixel 9 Pro Fold emulator profile.
The same layout rule applies to tablets and to phones held sideways: two pages when two fit comfortably, one when they don’t.
FAQ
Questions & answers
Does Tomelet show two pages on iPhone Duo and Galaxy Z Fold?
Yes. On the unfolded inner display Tomelet shows facing pages with the fold as the spine for EPUB, fixed-layout EPUB and comics; for a PDF, choose Facing pages in Page layout. You can switch any book back to one page.
What happens when I fold the phone while reading?
The page you were on continues on the cover screen as a single page, and unfolding restores the spread at the same place. Highlights, notes and pen ink stay where you put them.
Do right-to-left and vertical Japanese books open the right way?
Yes. Spreads follow the book’s page direction, so Arabic, Hebrew and vertical Japanese books start on the right-hand page and turn leftwards.
Do I have to pay for two-page reading?
No. Facing pages on foldables are part of the free reader. Tomelet Sync, the paid subscription, adds private sync across devices.
