Write in the margins
Underline, circle, sketch or work a problem beside the text — in EPUB and PDF alike.
iPhone Duo · Galaxy Z Fold
Unfold your phone. Open a book.
Tomelet turns the inner display of an iPhone Duo or a Galaxy Z Fold into a printed spread: two facing pages, the crease as the spine, your notes in the margins. Close it mid-sentence and the sentence is waiting on the cover screen.
Free, with no account. Most books open as a spread on their own.
Two pages, one crease
The big screen, finally used like a book.
A phone page stretched across a fold is not a book. Tomelet sets two pages side by side, paired the way a printed book pairs them — the first page alone, then two at a time — with the fold in the gutter, exactly where a book has its spine.
- The fold is the spineThe two pages meet at the crease, exactly where a printed book is bound.
- Every script, the right way roundArabic, Hebrew and vertical Japanese books start on the right-hand page and turn the other way.
- Every kind of bookEPUB, 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.
Apple Pencil on iPhone Duo
A pen in the margin of every book.
Apple is bringing Apple Pencil (USB-C) to iPhone Duo, on both displays. Tomelet’s pen tools are built for it: the day your Pencil works, it writes on every page you read.
Highlight with a stroke
Run the Pencil along a line to mark it, in colours you can tell apart at a glance.
Pen writes, fingers turn
The Pencil inks while your fingers turn pages, pan and zoom. No modes to switch.
Every mark, on every device
Highlights, notes and ink sync privately to your other devices with Tomelet Sync.
Fold and unfold
Close it mid-sentence. The sentence waits.
Folding the phone changes the screen, never your place. Nothing reloads, nothing jumps.
Straight to the cover screen
Fold the phone and your page carries on, as a single page, on the outside.
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-thought is fine
An open toolbar or a half-typed note is still there after the screen changes.
However you hold it
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.
On tablets, too
Tablets and phones turned sideways get the same spread: 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.
Can I write with Apple Pencil on iPhone Duo?
Yes, the moment Apple switches on Apple Pencil (USB-C) for iPhone Duo, on both displays. Tomelet’s pen tools are ready for it: ink, highlight and underline in the margins of any book, with your fingers free to turn the 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.
