Read full description

KeyCorder is a free Korean keyboard, redesigned from scratch. One key holds the plain, aspirated and tense consonants, so the whole layout fits in five columns β€” and the keys get bigger. Nothing you type leaves your device. β–  One key, three sounds Β· Tap β†’ plain (γ…‚) Β· Slide β†’ aspirated (ㅍ) Β· Hold β†’ tense (γ…ƒ) Tap twice quickly and it picks the right one from context. β–  Same key twice? It works it out On layouts where one key carries several letters, a repeat tap is ambiguous: is γ„±γ„± the single letter γ…‹, or a final γ„± followed by an initial γ„±? Usually you have to break it up yourself with a slide or a pause. KeyCorder decides from a dictionary instead. Β· 5-key, 7-key, full QWERTY β€” picks between γ…‹ and final+initial Β· Simple-vowel β€” decides between the tense γ„² and two separate letters Β· Cheonjiin β€” type straight through even when a final and the next initial share a key (μž₯마, μ•ˆλ…•), no slide needed If it read you wrong, one tap on the suggestion bar switches it. β–  Features Β· 5-key Korean input, repeat-tap auto-resolution tuned per layout Β· Word suggestions β€” next-word prediction, initial-consonant search, emoji hints Β· Emoji, symbols and Hanja conversion Β· Clipboard history with pinning Β· Press effects (ripple, bolt, snow, petal, ice) that react to touch Β· 16 themes, bundled fonts, your photo as keyboard background Β· Key size, font size, weight and border β€” all adjustable Β· Learned-word manager: review and delete what it learned Β· Typing stats with weekly speed graph Β· Split keyboard & one-handed mode Β· Number-only fields open a large number pad automatically Β· Layouts: 5-key, 7-key, full QWERTY, simple-vowel, Cheonjiin Β· Korean + English On first launch you pick a layout and a look (calm, vivid, neon, elegant); theme, font and press effect are set together. Reopen it anytime. β–  Privacy by default No data collection, no servers, no ads or trackers. The keyboard sends nothing you type anywhere, and learned data is even excluded from iCloud backup. Full Access is used only for clipboard history, haptic feedback, and sharing settings between the app and the keyboard. Clipboard history stays on-device, is excluded from iCloud backup, and can be disabled or cleared at any time from the keyboard panel. Every feature is free.

Type Korean with one thumb β€” and learn Hangul while you do. Hold a consonant and pull the way the vowel is written. Pull γ„± right and you get κ°€. Pull it up and you get κ³ . There is no vowel side to cross to, so your thumb stays where it is. Tap for a final consonant, pull for the next syllable. Those two lines are the whole rule. Because your finger says which one you meant, the keyboard never guesses β€” and nothing you have already typed changes shape behind the cursor. β–  How it types ㅏ is a vertical stroke with a mark to the right, so you pull right. γ…— is a horizontal stroke with a mark above, so you pull up. The shape of the letter is the direction of your thumb. Because a vowel arrives with the consonant that carries it, one gesture makes a whole syllable. β–  It stays where your thumb is Every vowel is reached from the consonant key itself, so your thumb doesn't travel β€” and no shift trip for tense consonants: press ⇧ and pull, or double-tap. One-handed mode moves the keys to either edge, and you can set the keyboard height β€” on a large phone that decides whether one hand is enough. β–  It doesn't guess No autocorrect. No word suggestions. No learning what you write. What you type is what you get, every time. β–  It doesn't take anything Nothing you type is stored. Nothing is sent anywhere. There is no networking code in this app at all β€” turn on airplane mode and everything still works. To fit the pull distance to your hand we count how far and which way your gestures go β€” never which letters, and never off your phone. β–  Learning Korean? The gesture itself teaches the structure: pulling γ„± right is "consonant + ㅏ" written with your hand, and a separate tap is what a final consonant is. Practice comes in four stages, from simple pulls to full sentences, with each word's meaning beside it β€” ν™”μž₯μ‹€, μ–Όλ§ˆμ˜ˆμš”, μΉ΄λ“œ λΌμš”. β–  What you can change Β· Pull sensitivity, or let it measure your habits and set itself Β· How long a linked pull stays open (ν•˜ν•˜ vs 햐) Β· When haptics fire and how strong Β· Keyboard height and skin Β· Hand fit β€” we watch where you actually land and move the target under it From the app or from inside the keyboard, either way. β–  Pick a layout Four, switchable any time in Settings. Β· PullKey β€” pull a consonant and the vowel attaches. Β· Simple vowels β€” 2-set minus γ…‘γ…•γ…›γ… , so every key grows. Those four come from tapping a key twice, quickly. Β· Mui β€” simple vowels minus γ…Œ and ㅍ; twenty keys. Β· Standard 2-set β€” the same layout as the stock iPhone keyboard. Until PullKey feels natural, use the one you know. β–  Pick how it looks Fifteen colours and thirteen quiet pictures. Each one is drawn as a small keyboard, so what you pick is what you get. On a picture you also choose how solidly the keys sit on top of it. β–  Also Β· Latin letters, numbers, symbols, emoji Β· Pull space sideways to move the cursor, up to switch Hangul/Latin Β· Pull delete left to erase a word, up to erase to the end of the line Β· Save phrases with a title, enter in one tap; {였늘} {μ‹œκ°} fill in date and time Β· Abbreviations β€” only pairs you wrote, expanded on space Β· Optional row above the keys β€” Hanja, kaomoji, calculator, romanize, swap ν•œ/A, date math Β· Five key sounds, three loudness levels Β· Number row; two spaces for a full stop β–  Free and Pro The keyboard is free: all four layouts, Latin and symbols, sensitivity, hand fit, one-hand mode, haptics, cursor pulls, word delete, typo guard and practice. No trial, no expiry. PullKey Pro opens looks and extras: Β· Themes β€” 15 colours, 13 pictures (three free) Β· Six fonts, five key sounds Β· Toolbar β€” phrases, Hanja, calculator, kaomoji, romanize, swap ν•œ/A, date math Β· Abbreviations, phrase placeholders, the Lab $6.99 once, yours for good.
