Unfortunately, we are no longer able to support SwiftKey on Android KitKat devices.
You can check your Android version number by visiting your phone Settings. Depending on your phone you'll then tap into the System or About menu.
Android KitKat version numbers range from 4.0-4.4.
We want to make sure you have a great SwiftKey experience and we can no longer provide that on Android KitKat and below.
As SwiftKey and Android have grown over the years, the best SwiftKey experience can be had on newer versions of Android.
