I REALLY like this keyboard, I actually bought it about a month ago for $2.49, of course it is now FREE with the Amazon Appstore.
Regular price of Thumb Keyboard App is $2.46 but it is FREE for today only. Sign in to Amazon Appstore for Android to get this app for FREE. If you don’t already have the Amazon Appstore for Android installed install it!! The Amazon Appstore offers one app that normally costs money for FREE. One a day!
