VKey is a Vietnamese keyboard (input method) that supports two typing methods in Vietnamese: Telex and VNI. It is a powerful keyboard that can suggest the best next word during typing and learns your typing habits to adapt to you.

Some of the standout features of VKey include word prediction based on context, learning and adapting to the user, synchronizing words on iCloud, and the ability to manually delete sensitive words by long-pressing on suggested words. It also supports swipe-to-type, fully supports Emoji for iOS 10, and has Telex and VNI input methods and keyboard layouts that adjust to Vietnamese to avoid mistyping. Additionally, it offers abbreviation for texting, the ability to change themes and typing sounds, and the option to swipe on the space bar to move the cursor. VKey provides many more options to optimize the typing experience.

Please note that VKey requires users to allow full access for using themes, typing sounds, and the word prediction feature. VKey does not collect any typing data from users.
