## What is TwoUp Split Screen Dual Window?

TwoUp puts two things on one iPhone screen at the same time: a web page, a PDF and a
plain-text note, in any combination you need.

Read a PDF above and write your notes below. Keep a reference page open beside the
document you are working through. Both panes stay live — scroll one and the other keeps
its place.

SAVE THE PAIR
A pair of panes is a workspace. Name it, and it reopens exactly as you left it: the same
document, the same page, the same note text, the same divider position.

MADE FOR READING
Drag the divider to give either pane more room, or send one pane full screen and back.
Turn the phone sideways and a PDF opens as a two-page spread, like a book, with your note
still beside it.

YOUR OWN SITES — WITH PRO
Save the pages you keep coming back to, with their titles and icons, and open one into a
pane without typing an address.

IT ALL STAYS ON YOUR PHONE
No account, no sign-in, and no server of ours. Your notes, your documents and your saved sites never
leave the device — there is nowhere for them to go. The app asks for no permissions at
all: no camera, no photos, no contacts, no location.

The app sends anonymous usage statistics so we can see which screens people reach and
where they get stuck. None of your content is ever included — not your notes, not the
addresses you open. You can switch it off in Menu > App > Share usage data.

TwoUp Pro adds two things: keeping more than one saved workspace, and saving your own
sites as shortcuts.

## Version history (last 5 releases)

### 1.4 — 2026-10-14

New icon: two panes, one screen. Plus small improvements and fixes.

### 1.3 — 2026-09-23

The upgrade screen now spells out what each plan works out at per month, so the two are easy to compare side by side.

And there is a new switch in Menu > App: Share usage data. It is on by default and sends anonymous statistics about which screens are reached — never anything you write.

### 1.2 — 2026-09-11

A new introduction on first launch, and a redesigned upgrade screen: both plans, what each costs and what they unlock now sit on one screen, with the terms beside the button.

### 1.1 — 2026-09-10

A redesigned upgrade screen: the two plans, what each costs and what they unlock now sit on one screen without scrolling, and the terms are next to the button rather than below the fold.

Split screen rebuilt. The two panes re-lay themselves out when the display area changes size or proportion, keeping their content and scroll position. The divider is easier to grab, full screen and back is immediate, and in landscape a PDF fills the available room as a two-page spread with the note beside it.

Saved workspaces still reopen exactly as you left them.

### 1.0 — 2026-09-08

No release notes.
