This is my "QUADDING" app - BRAILLE VERSION! Use the hint magnifying button to peek at the roman letter equivalents for about 1 sec. You are presented with four words of four letters each. Your challenge is to unscramble each group of letters to form the four correctly spelled words. You might get several of he words correct but you'll need to get all four correct before you can move on! Correctly spelled words do not imply they are part of the whole quad - you might have to use letters of correctly spelled words to complete other words. There are 500 quads - good luck!

Verdict
The clearest difference is price: Commtech USA at Free against Quad Braille's $1.99. Commtech USA also leads on device support (5 vs 3). Quad Braille's advantage is update cadence (daily vs every 21 months) and iOS requirement (11.0 vs 14.0). On ads and in-app purchases there is nothing between them.
