DeepPad is a Korean and English keyboard that learns you as you type. Touch correction, auto translation, handwriting, voice and photo recognition. Enjoy English Speaking and Case Deduction too. It looks and works just like the iPhone keyboard, so there is nothing new to learn. The difference is inside. ■ Fast first Letters go in the moment you touch a key. Whatever else the keyboard does, typing speed comes first. ■ The next word, before you type it Three likely next words sit right above the keys. Whether to take one is up to you. Slipped onto the key next to it? DeepPad works out what you meant and still shows what comes next. It even understands Hangul mid-syllable, when a final consonant is about to move to the next character. ■ Learns your words It remembers the words you use, the order you put them in, and the words you have corrected, and suggests those first. Names and slang that no dictionary knows become your words after you type them twice. See everything it has learned in the app's Typing Report, and delete any of it, or all of it, any time. ■ Stops typos as you type, changes text only when you tap · The key you press lights up clearly, so you notice a one-key slip right away. · It learns where your thumb lands and adjusts key edges slightly. · Keys you often miss feel slightly different under your finger. No silent autocorrect. Your words change only when you tap. ■ English right there Live Korean ↔ English translation appears above the next words as you type. Type Korean to see English, type English to see Korean. Tap to use it, or just read along. Translation runs on your device with Apple's translation engine. Download the language pack once and it works offline. ■ Learning Korean? · Draw Hangul by hand. No need to know the layout yet. On-device AI reads Korean, English, numbers and symbols. · Type English and see it in Korean as you go. · Practice right in the app. ■ Three more ways in · Handwriting: write straight on the keyboard. · Voice: tap the mic, speak Korean, get text. · Camera: point at text on paper or a screen and bring it in. ■ Practice that teaches the keyboard · Next Word Guess: reply to a friend's message. If the keyboard already had your word, that is telepathy. If not, it learns it on the spot. Five cards and your real keyboard already feels different. · English Speaking: see a Korean sentence, answer in English by voice or typing. · Case Deduction: solve a mystery with yes-or-no questions. ■ Your words stay on your phone Everything the keyboard does, next words, translation, handwriting and learning, happens on your device. Nothing goes to our servers. In password and number fields it shows nothing and learns nothing. Only practice mode uses Apple's Private Cloud Compute: judging answers and writing cases in Case Deduction, and one word of context when writing the friend's message in Next Word Guess. Apple does not store it. * Haptics need Allow Full Access in Settings. * Case Deduction needs a device with Apple Intelligence turned on. English Speaking and Next Word Guess work without it, and write fresh sentences when it is on. On iPad mini and on iPhone Duo unfolded in landscape, you can split the keyboard in two, just like the built-in one, and type with both thumbs. Switch between full and split from the menu on the left of the bar.

About

KeyCorder

Features
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 — and the keys get bigger. Nothing you type leaves your device. ■ One key, three sounds · Tap → plain (ㅂ) · Slide → aspirated (ㅍ) · Hold → tense (ㅃ) Tap twice quickly and it picks the right one from context. ■ Same key twice? It works it out On layouts where one key carries several letters, a repeat tap is ambiguous: is ㄱㄱ the single letter ㅋ, or a final ㄱ followed by an initial ㄱ? Usually you have to break it up yourself with a slide or a pause. KeyCorder decides from a dictionary instead. · 5-key, 7-key, full QWERTY — picks between ㅋ and final+initial · Simple-vowel — decides between the tense ㄲ and two separate letters · Cheonjiin — type straight through even when a final and the next initial share a key (장마, 안녕), no slide needed If it read you wrong, one tap on the suggestion bar switches it. ■ Features · 5-key Korean input, repeat-tap auto-resolution tuned per layout · Word suggestions — next-word prediction, initial-consonant search, emoji hints · Emoji, symbols and Hanja conversion · Clipboard history with pinning · Press effects (ripple, bolt, snow, petal, ice) that react to touch · 16 themes, bundled fonts, your photo as keyboard background · Key size, font size, weight and border — all adjustable · Learned-word manager: review and delete what it learned · Typing stats with weekly speed graph · Split keyboard & one-handed mode · Number-only fields open a large number pad automatically · Layouts: 5-key, 7-key, full QWERTY, simple-vowel, Cheonjiin · 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. ■ 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.
