I develop Typefinity, a custom keyboard app for iPad and iPhone designed for usability and efficiency on tablets and modern large phones.
• Number row and full punctuation on main layout
• Cursor keys
• Opt key to access additional symbols and accent keys, and activate move / delete by word mode
• Forward delete and tab keys on some layouts / devices
• Display more than three word suggestions
Also: Swipe input, short mode, selectable themes and sounds, number pad on demand, intelligent punctuation spacing, emoji search, and more. We support 22 layouts in 14 languages.
The stock keyboard was designed for the orginal 3.5" iPhone screen. If you'd like a more powerful, convenient way of typing on your modern device – not just bigger keys – consider Typefinity.
* Note, Typefinity is a paid app. We make our money by selling the keyboard, not our users' data. In fact we don't use the network at all, and you don't need to grant so-called "Full Access" to the keyboard for any functionality, except if you want to use our paste and undo buttons instead of the system's.
