Duoboard

Type with whichever thumb is free.

Duoboard is a keyboard for the iPhone Duo. Open it like a book with two apps side by side, and type on the left half, the right half, or both.

Duoboard in Dual mode on an iPhone Duo: a full keyboard under each thumb, typing into Notes on the left while a chat with Sam is open on the right.

  • English (US)

Two apps open, one hand on the phone. Duoboard puts the keys under the thumb that’s free.

Three modes

Half, Dual or Full.

Switch from the keyboard’s top row, the same way the film does. On the outer screen or any other iPhone, Duoboard is a normal single keyboard.

Half mode: the keyboard under the right thumb in a chat with Sam, while Notes stays in full view on the left half above 123, Emoji and Suggestions buttons and “Move keyboard here”.

Half

One keyboard on one half of the display, under one thumb. The other half keeps its app in full view.

Tap Move keyboard here on the other half to switch sides, or put that half to work below.

Dual mode: a full keyboard under each thumb, one on each half, typing “Keep a keyboard under each thumb” into Notes.

Dual

A full keyboard under each thumb. Both type into the app you’re in, so you can alternate thumbs like on a regular phone.

Full mode: one classic keyboard spread across the whole open display, replying to Sam.

Full

One classic keyboard across the whole open display, the layout you already know.

The other screen

The ultimate Duo keyboard.

In Half, the screen beside the keys isn’t left empty. One tap and it holds emoji, numbers and symbols, more suggestions, your snippets or your clipboard, right next to the letters.

Keys on the left half, emoji open on the right: “Sunset at the Miradouro 🌅🍷” typed in Notes without switching pages.

Dual wield text and emoji ⚔️

Keys on one screen, emoji on the other. Every emoji, with search and skin tones, and no switching.

Keys on the left half, a big number pad and symbols on the right: “Flight TP 218 leaves 7:40” typed in Notes.

A dedicated number pad

Right beside the letters, with every symbol from the system keyboard. Plus search for any symbol you can think of, like ‽.

Keys on the left half, nine big suggestions on the right for “phot”: photo, photos, photograph and more.

Even more suggestions

Get up to nine text suggestions as you type: the word you’re on, its near misses and how it could end.

Keys on the left half, saved snippets on the right: tapping Hotel answers Sam’s “Where should I pick you up?” with the hotel’s address.

Quick access to what you type most

Save your address, email and go-to replies as snippets, and they’re one tap from the keys.

Swipe and autocorrect

Quick on either half.

Swipe a word or tap it out. Duoboard fixes slips as each word ends, and the strip above the keys always has another option.

A swipe trail from s up to o and down to n, swiping “soon” after “See you”, with you, toy and thou in the strip above the keys.

Swipe typing

Glide through the letters on either half and lift. The likeliest word goes in, and two alternatives wait in the strip.

After typing “palce”, the message reads “Yes! Love that place.” and the strip offers “palce” in quotes, place in bold, and palace.

Autocorrect

Typos are fixed when the word ends. What you typed stays in the strip, in quotes, and backspace puts it back.

how it goes

Missed the space bar? A letter just above it can count as a space, so a run-on like this comes out as the words you meant.

  • Suggestions strip

    Alternatives for the word you’re on, one tap away.

  • Replacements

    Select a word and the strip offers replacements for it.

  • Learns your words

    Words you pick from the strip are remembered on your iPhone.

  • Cursor on the space bar

    Hold space, then slide to move the cursor.

  • Every emoji

    Search by name, pick skin tones, and your favorites first.

  • Snippets

    Save your email, address or go-to replies, and insert them with one tap.

  • Clipboard

    What you copy, kept for later and a tap away beside the keys.

  • One-handed on the outer screen

    Flick the space bar toward your thumb, or hold the emoji key.

  • Your words

    See, add and forget the words Duoboard has learned.

  • Haptics, light and dark

    Optional key haptics, and colors that match the system keyboard.

Privacy

What you type stays on your iPhone.

The keyboard never uses the network. There’s no account, no analytics and nothing to sync.

Questions

FAQ

Does it work on a regular iPhone?

Yes. On a regular iPhone, and on the Duo’s outer screen, Duoboard is a single keyboard with the same swipe typing and autocorrect. The Half, Dual and Full modes are for the Duo’s open display.

Why does it ask for Full Access?

It doesn’t need it. Full Access is optional and turns on key haptics, remembering words you pick, clipboard history and snippets. All of them stay on your iPhone.

Does it send what I type anywhere?

No. The keyboard never uses the network, and everything it does happens on your iPhone. The app goes online only to check your Pro purchase.

Which languages does it support?

English (US).
