Thoughtful about
the in-between.
A fold is a boundary.
Your page and controls use the available regions around a reported hinge. When there isn’t room for two usable panes, the notebook returns to a focused view.
A place for your hands.
On open, wide layouts, move the sidebar to the left or right. In a book fold, a focused list-and-page layout keeps both sides useful.
Make the layout yoursA notebook for Android foldables.
The Android layout responds to window size and the fold information a device provides. Layouts have been checked in a Pixel Fold emulator; physical devices and manufacturers can differ. Android foldable support is in development.

A few answers about iPhone Duo, Android foldables, and the app in development.
See app and cloud pricingIs Nostella a notes app for iPhone Duo?
Yes. Nostella is being designed for iPhone Duo, with compact views for quick capture and wider layouts for browsing beside a note. The app is still in development.
How do book and tabletop layouts work?
Book fold places the browser on the left and the selected preview on the right. Tabletop places the preview above the fold and the browser below it. Each layout keeps content clear of the crease.
Can I write or draw in a folded layout?
Book and tabletop layouts are for browsing and previewing notes, folders, reminders, saved recordings and Settings. Use a regular closed or open-flat view to create or edit content. Eye Saver can still be changed in the Settings preview.
Will Nostella work on Android foldables?
Android foldable layouts are in development and have been checked in a Pixel Fold emulator. Physical devices may differ. The layout depends on usable screen space and the fold information a device provides.
What happens when there is not enough room for two panes?
Nostella returns to a focused view when there is not enough space for the browser and page side by side. A reported hinge remains clear of the active content.
Are these screenshots from a real device?
The screenshots and interactive model use the current Nostella app UI, rendered with example content and simulated device layouts. They show the app’s layout, rather than a physical-device test.
