Rot-13 (short for rotate 13) is a simple letter substitution cipher that was popular in online forums for hiding spoilers, punchlines, offensive material, and other things from a casual glance. It works by replacing the current english letters in a message with those that are 13 positions ahead in the alphabet. For example, the letter a is replaced by n, b by o, c by p, etc. Numbers and punctuation are not encoded. This lets you type in and convert with the app, share text from another app to convert, or include in a shortcut.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
KSBTECH holds the better App Store score, 3.8 against 3.7. That said, the two scores are not equally well evidenced: KSBTECH has 218 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 75% of Rot13 (Unix Flashback)'s written reviews are positive against 58% of KSBTECH's, so the app with the better star average is not the one people write more warmly about.
Rot13 (Unix Flashback) ships an update every 26 months, KSBTECH every 3 weeks. Both last shipped on November 11, 2026.
