BrailleEasy is a free iOS app that is fully compatible with VoiceOver. This app uses a custom touch-screen keyboard that divides the braille cell into two columns. With the simple adaption of transforming two-handed brailling into two gestures, users can quickly learn how to use this keyboard. Begin by entering the dots for the first column, then enter the dots for the second column. A BrailleEasy-Tutor with simple lessons is included to practice the one-handed or unimanual braille input method.
