Boomerang One-Hand Keyboard
Utilities
Free · Designed for iPad. Not verified for macOS.
One thumb, full keyboard. Boomerang moves every key toward your thumb — or switch to a familiar Standard QWERTY anytime. No Full Access, no tracking, ever.
One thumb. Full alphabet.
Boomerang is a custom keyboard built for typing with a single thumb. Instead of shrinking the standard QWERTY grid, Boomerang rearranges every letter, number, and symbol so the keys you use most sit closest to your thumb — no stretching, no missed taps, no second hand required.
HOW IT WORKS
- Every English letter appears exactly once, rebuilt into a compact five-row layout anchored to your thumb's natural reach.
- Three live suggestions sit on a wide rail at the edge of the keyboard, each paired with a one-tap thumb shortcut.
- One key instantly mirrors the entire layout for your other hand — the suggestion rail, shortcuts, and edge controls all move together.
- Numbers in phone-style order and a full symbol board are one tap away.
PREFER A FAMILIAR LAYOUT?
Switch to Standard mode for a conventional, unsplit QWERTY keyboard with a classic suggestion bar above the keys — same on-device suggestions, familiar shape. Tap once to switch between Boomerang and Standard; long-press to jump to any other keyboard you have installed.
LEARN AT YOUR OWN PACE
Turn on Learning Colors to tint each key with the color of its original QWERTY row, so the new positions map back to muscle memory you already have. Turn it off once Boomerang's arrangement feels natural.
BUILT TO STAY OUT OF YOUR WAY
Boomerang works without requesting Full Access. It has no network connection, no analytics, no accounts, and no cloud prediction — suggestions come entirely from your device. The only setting it stores is shared privately between the app and the keyboard extension, and it's never uploaded anywhere.
WORKS EVERYWHERE YOU TYPE
Boomerang supports iPhone and iPad, portrait and landscape, light and dark mode, and both hands. Standard system behaviors — emoji, dictation access, keyboard switching, shift and caps lock — all work exactly as expected.
Boomerang doesn't ask you to learn a new alphabet order for its own sake. It asks you to trade a small, one-time learning curve for a keyboard that finally fits how you actually hold your phone.
Boomerang now comes in two shapes.
NEW: Standard layout — a familiar, unsplit QWERTY keyboard, for when you want the classic shape instead of Boomerang's one-thumb layout.
NEW: One key switches between Boomerang and Standard instantly. Long-press the same key to jump to any other keyboard you've installed.
NEW: Standard mode shows your suggestions in a classic bar above the keys, powered by the same on-device suggestions Boomerang has always used.
Minor polish and stability improvements.
