KeyCorder

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.

■ 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.
