Converts a string into a string shifted the specified number of characters. The number of characters to shift is specified as the conversion parameter. For example, to shift the string AAAA by one character, set the conversion parameter to 1 and the selected string to AAAA. In this case, the converted string will be BBBB.

Verdict
The clearest difference is ads: Green Access at none against Caesar's shown. Green Access also leads on iOS requirement (13.0 vs 15.0). Caesar's advantage is update cadence (every 2 weeks vs every 3 months). On price, in-app purchases and device support there is nothing between them.
