EmailFaster and TextFaster are two free applications with big keys. To type a letter you just swipe one of the big keys once. The keys are laid out like a familiar T9 cell phone keyboard. To type an a, you swipe the abc key to the left. To type a c, you swipe the abc key to the right. To type a b, you just tap the abc key.
EmailFaster uses this keyboard to allow you to compose Email messages. TextFaster allows you to compose Text Messages.
On the iPhone and iPod Touch, TextFaster is great for those who find the regular iPhone keyboard too small. On the iPad, it has huge buttons, and so is great for those with physical disabilities.
Remember swipe, dont just tap!
