MergeKey
Dynamic Keyboard
Free · In-App Purchases
31 languages, 14 styles, custom colors, split keyboard and two-finger trackpad on iPad. The keyboard that only shows the letters you need.
MergeKey — the first keyboard that hides the keys you don't need.
As you type, MergeKey dynamically removes impossible letters and expands the remaining keys, giving you bigger tap targets and fewer typos. It's like autocomplete, but visual — you see your options shrink in real time.
MERGE MODE — UNIQUE TO MERGEKEY
- Keys that can't continue your word disappear instantly
- Remaining keys grow to fill the space — bigger keys, fewer mistakes
- Learns new words you teach it
- Toggle Merge Mode off if you prefer just the disappearing keys without resizing
MADE FOR IPAD
- Full-size layouts on large iPads, a roomier compact layout on smaller ones
- Pinch to split the keyboard for thumb typing, with adjustable split distance
- Two-finger trackpad: drag across the keys to move the cursor
- Letters Only mode for a clean, focused board
- Split typing on iPhone too, in landscape

PRIVACY FIRST
MergeKey does not collect or transmit your typing data. Everything stays on your device.
MergeKey never connects to the internet. The only network activity is the App Store handling the optional tips – that's why iOS shows a Mobile Data switch for MergeKey.
The optional clipboard keeps your texts on this device only.
