Fleksy is an interesting take on alternate text input for the iPhone. Designed for those whose eyesight is bad or nonexistent, Fleksy records the taps on the screen and makes a guess based on your patterns. It then says the word, enabling you to quickly construct sentences without even looking at the screen. Does it work? Absolutely it does, and as proof I found it was far more accurate when I didn't look at the screen than when I tried to type quickly while looking at the "keys."
Fleksy is simple enough, with a text area up top and modified keyboard below. As you type, it guesses what you're trying to type. When you go to the next word by swiping right, Fleksy reads the word it guessed, allowing you to delete it (swipe left to delete), ask for another suggestion (swipe down), or continue by typing again.
What's incredible is the speed and accuracy of the app while not looking at the screen. If you're familiar with the basic QWERTY layout on an iPhone's screen, you can tappity-tap on the screen, pretending you're seeing the keys, when Fleksy is actually making several educated guesses about what you're wanting to write.
Fleksy is free to test, and I highly recommend you do so to understand what's going on. My video below is but a tiny sample of how good Fleksy is at guessing your keystrokes. To unlock the ability to use this text outside of the app, it'll cost you $9.99. If you are visually impaired, it's a decent bargain, even though Apple continues to make iOS more accessible.
