SwiftKey Keyboard has been announced for iPhone, iPad and iPod Touch, Digital Spy reported.

The keyboard app, which has been available on Android for some time, monitors the user's typing style to offer services such as intelligent next-word prediction.

SwiftKey Keyboard provides faster, more accurate suggestions the more it is used, and can be synced with email, Facebook and Twitter accounts to learn from them.

The app stores information about the user's typing style in the cloud, so their preferences can be synced across devices.

The SwiftKey Flow feature, which lets device owners type by sliding from letter to letter, will only be available on iPhone and iPod Touch.

SwiftKey Keyboard will be available through the App Store on September 17.
