Read full description

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. No account, no ads, no tracking. DUOBOARD PRO The Full keyboard is free, with autocorrect, emoji, snippets and your clipboard. Duoboard Pro unlocks Half, Split, Dual, Live Edit and swipe typing: try it free for 7 days, then keep it with a one-time purchase. No subscription.

On the outer screen, it goes full width. • A thumb swipe or a tap on the other side moves it right away. MADE FOR YOUR THUMB • One hand left, one hand right, full width or two hands. • Adjust the width, the distance from the edge and the key height. • Your usual phrases above the keys and your emoji in the free space: one tap. ALL THE BASICS • QWERTY and AZERTY, accents on long press. • Auto-correction and word suggestions. • Capital letter at the start of a sentence, double space for a period. • Slide on the space bar to move the cursor. MAKE IT YOURS • 8 color themes and 4 fonts. • 4 typing sounds and the vibration strength you like. PRIVATE Foldboard never sends what you type. No internet access, no account, no ads.
