# Unfold. *See the whole document.*

> Nimbo is laid out for iPhone Duo. Unfolded, the Library, page thumbnails or the Ask conversation sit beside your PDF; fold it and nothing is lost.

On iPhone Duo, Nimbo uses the inner screen for two things at once: the list and the document, the PDF and its thumbnails, the original and its translation. Fold it and you are back to the iPhone you know, on the same page.

Fold and unfold

## Key facts

- **Works on:** iPhone, iPhone Duo (folded and unfolded) and iPad, including Split View
- **Folding:** Nothing is lost: the page, the zoom, the conversation and a scan in progress carry over when you fold or unfold.
- **Upload:** Scans, conversions, signatures and compression run on the device. The AI features send the text they need only when you use them, after asking you once.

iPhone Duo

## Library and document, side by side.

Unfolded, the Library stays on one side while the document opens on the other, in the system split view. Tap another file and it takes the document's place; the list stays where it is.

iPhone Duo

## Thumbnails beside the PDF. *Two pages in landscape.*

The Reader shows the page thumbnails next to the document, so jumping to a page is one tap. Turn the phone and two pages sit side by side, like an open book.

iPhone Duo

## Ask, with the PDF in view.

The conversation sits next to the document. Tap a cited source and the PDF jumps to that page, without closing anything. One button puts the PDF in full screen; the same button brings the conversation back.

iPhone Duo

## Original and translation, page for page.

Translate shows the original on one side and the translation on the other, with synchronized paging: turn a page and both move together.

iPhone Duo

## Drop files straight into the Library.

Open Files or Photos beside Nimbo and drag PDFs or images into the Library. They are imported on the device, like with the Share extension.

iPhone Duo

## Laid out for the big screen.

Home, Create with AI and the Nimbo Pro screen are laid out for the inner screen instead of stretching the iPhone layout.

iPhone Duo

## Fold. Unfold. *Nothing is lost.*

The page you are on, the zoom, the Ask conversation and a scan in progress all carry over when you fold or unfold. Closed, you see the last screen; open, the last two.

iPad

## The same layouts on iPad

Everything on this page follows the width available, not the device: the two-pane layouts also serve iPad and Split View, and the one-column layout serves every iPhone.

## Frequently asked questions

### Does Nimbo work on iPhone Duo?

Yes. Folded, Nimbo works like on any iPhone. Unfolded, it uses the inner screen for two-pane layouts: the Library beside the document, thumbnails beside the PDF, the Ask conversation or the translation beside the original.

### What happens when I fold or unfold?

The layout switches between one and two panes, and you stay where you were: same page, same zoom, same conversation, and a scan in progress continues.

### Does it work on iPad too?

Yes. The same layouts follow the width available, so they serve iPad and Split View as well.

### Is my document uploaded?

Scans, conversions, signatures and compression run on the device and send nothing. The AI features (Create, Transform, Translate, Ask) send the text they need to our server only when you use them, after asking your permission once; requests are not stored and generated documents are deleted within 24 hours.

### Is everything free on iPhone Duo?

The rules are the same as on every iPhone. Scanning to PDF, importing photos and files and the Library are free. The PDF tools, signing included, and the AI features are part of Nimbo Pro. The monthly plan starts with a 3-day free trial for new subscribers.

## Private by design

Scans, conversions, signatures and compression run on the device. The AI features send the text they need only when you use them, after asking you once.
