Duo Keyboard: Resize & Split

Lower your keyboard to see more of your text, and bring the keys closer to either thumb.
Duo Keyboard lets you choose the size and position that suit your hands. Split the keys on a wide screen and switch between two inputs chosen from 30 languages and emoji. Buy once, with no subscription or in-app purchases.

MORE ROOM FOR YOUR TEXT
Adjust keyboard height and width while watching the keys change. Settings open above the live keyboard. Make a one-handed layout smaller or expand it to the available width. Center fills the keyboard width assigned by iOS.

LEFT HAND OR RIGHT, KEEP THE KEYS CLOSE
Swipe the switch key left or right for one-handed placement, or up to return to full width. Swipe the empty keyboard area to bring the keys to the other side. Hold the switch key to open settings.

SPLIT THE KEYS ON A WIDE SCREEN
Place the keys on both sides when holding your device with two hands. Swipe the switch key down to split when the input area is wide enough. The two banks keep a gap as you resize them. Narrow and wide layouts remember their own size and position.

CHOOSE YOUR TWO INPUTS
In Typing, choose a language and layout for Primary and Secondary. Tap the switch key to move between them. Pair English with Spanish, French with emoji, or choose another combination that works for you.

30 INPUT LANGUAGES
Korean, English, Spanish, French, German, Russian, Portuguese, Italian, Indonesian, Vietnamese, Turkish, Polish, Ukrainian, Dutch, Swedish, Malay, Filipino/Tagalog, Arabic, Hindi, Thai, Bengali, Urdu, Persian, Chinese, Japanese, Marathi, Javanese, Nigerian Pidgin, Telugu and Tamil.

Chinese supports Pinyin with Simplified and Traditional conversion; Japanese supports romaji with kana and kanji conversion; Vietnamese supports Telex. Arabic, Hindi, Thai, Bengali, Urdu, Persian, Marathi, Telugu and Tamil use paged character entry. Javanese uses Latin script. General autocorrection and next-word prediction are not provided.

NO FULL ACCESS REQUIRED

Try layouts in the app before enabling the keyboard. Optional bug reports are emails you review and send yourself; the report and reply address are received for support.

BEFORE YOU BUY
• iOS controls the available width and bottom system area. Margins may remain on some devices or in some apps. Split mode requires a wide enough input area.
• Empty areas around or between the keys remain part of the keyboard. They do not reveal the document underneath. There is no free-floating keyboard or system mouse pointer.
• iOS may use its own keyboard in password or certain phone fields, and in apps that disallow third-party keyboards. Some fields do not accept newlines.
• In-app practice settings are separate from the actual keyboard's saved settings.
• On a wide screen, after moving the keys and reopening the keyboard, the previous position may briefly appear before the saved position is displayed.
