Duo Keyboard vs Duoboard

On a closed iPhone Duo, lower the keyboard to keep more of the message in view while you write your reply. Look for Sunday’s plans in the first screenshot. With the same Safari note open, switching from the English system keyboard to Duo Keyboard at 120 pt reduced the keyboard and input toolbar from 47.7% to 32.1% of the screen height. Two more lines of the note came into view. This example was measured on a closed iPhone Duo simulator in portrait on iOS 27.1. WHEN YOU CHANGE HANDS Swipe the language switch key left for a left-handed keyboard or right for a right-handed keyboard. You can also swipe the empty space beside the keys to bring them over to the other side. WHEN YOU OPEN YOUR DUO On a wide screen, swipe down on the switch key to split the keys between your thumbs. Swipe up to bring them back together at full width. Duo Keyboard remembers your size and position separately for narrow and wide screens. YOUR SIZE AND LANGUAGES Hold the switch key to open settings above the keyboard. Adjust height and width while watching the keys change.

Tap Add New Keyboard and choose Duo Keyboard. 3. In a text field, hold the globe key and select Duo Keyboard. 4. Hold the actual keyboard's switch key to set size, placement and inputs. BEFORE YOU BUY • iOS controls the available width and bottom system area. Margins may remain on some devices or in some apps. Split mode requires a wide enough input area. • Empty areas around or between the keys remain part of the keyboard. They do not reveal the document underneath. There is no free-floating keyboard or system mouse pointer. • iOS may use its own keyboard in password or certain phone fields, and in apps that disallow third-party keyboards. Some fields do not accept newlines. • In-app practice settings are separate from the actual keyboard's saved settings. • On a wide screen, after moving the keys and reopening the keyboard, the previous position may briefly appear before the saved position is displayed.

Duoboard puts your keyboard on one half of the open iPhone Duo and a productivity sidekick on the other. Or split the keys across both. LIVE EDIT No more cursor dance. Everything you've typed shows up right beside the keys, word by word, big enough to hit. Tap any word to swap it, fix it or retype it, without wrestling with the text in your app. Pinch two words to join them, or spread one to split it. In Half and in Split. HALF The keys on the screen you're holding, and your sidekick on the other: Live Edit, emoji with search, a number pad and symbols, your snippets and your clipboard. SPLIT One keyboard, a half under each thumb, like on iPad. Spread two fingers on the keys to split them, pinch to bring them back together, and drag the halves wider or narrower to fit your hands. Choose which keys show on which side. DUAL A whole keyboard under each thumb, split across the fold. FULL Or keep it classic, one keyboard across the whole screen. ONE-HANDED, WITHOUT THE FUSS • Sweep two fingers or flick the space bar toward a thumb, and the keyboard drops into Half under it. Sweep again to tuck the keys in for one hand. No holding the globe key, no menu. • On the closed Duo, flick the space bar toward your thumb for one-handed keys, and back for full width. • Drag the keyboard to any height and set its width, remembered for closed, open upright and open sideways. TYPES THE WAY YOU DO • Swipe typing, with suggestions as you swipe • Autocorrect that learns your words and your contacts' names, and reads the words before it • Next-word suggestions after a space • Missed spaces come apart: "itsjust" becomes "it's just" • Hold the space bar for a trackpad: the higher your thumb, the faster the cursor • Hold 123 for snake_case, kebab-case, camelCase or file paths • An optional number row, and a touch and hold on a letter for its accents • Emoji search that forgives typos • What you just copied waits in the suggestion bar, one tap to paste • Undo and redo in the suggestion bar • Set how fast the delete key repeats SNIPPETS AND CLIPBOARD Save the things you type all the time, your address, your email, a go-to reply, and send them with a tap. Duoboard can also keep what you copy, so it's there when you need it again. ON IPAD TOO Duoboard works on iPad too, Split and Live Edit included. PRIVATE Nothing you type leaves your device.
