Does not work on iOS 26, don’t waste your money.

An essential for those Gray code conversion needs.

So, you are working on a project with an incredibly tight deadline, and are confronted with a seemingly impenetrable Gray code bearing encoder. You fill your mind full of ones and zeroes which just don't seem to make any kind of sense.

This app does exactly what it is designed to do, to convert to and from Gray code. That impenetrable binary stream now becomes a decimal, something understandable by a human being.
