About

FastKeyboard`

Features
Read full description

FastKeyboard` is for people who care how a sentence is punctuated. Tap a letter and you get the letter. Flick up and you get the mark printed above it. Each row of letters has one job: digits on top, delimiters in the middle, and the marks that start or end a phrase along the bottom. The number keyboard is for equations and data. The symbol keyboard is there when you would rather tap a mark than flick it. It does not autocorrect, suggest words, or offer swipe typing. The character you choose is the one that appears. It does not request Full Access. It has no network access, and nothing you type is sent off the device. Add it in Settings → General → Keyboard → Keyboards → Add New Keyboard. In any app, long-press the globe key and switch to FastKeyboard. English QWERTY, on iPhone and iPad. iPad uses the same keys, with larger keys and wider gaps.

About

Duoboard

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.
