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.
