ROT13 ("rotate by 13 places") is a cypher used in online forums as a means of hiding spoilers, punchlines, and puzzle solutions from the casual glance.
ROT13 is its own inverse; that is, to undo ROT13, the same algorithm is applied, so the same action can be used for encoding and decoding. ROT13 has inspired a variety of letter and word games on-line, and is frequently mentioned in online conversations.
ROT13 for iPad is simple to use and offers tons of features. Just type your message (in any language or even coded text) and instantly (and without Internet required), your message will be ROT13'd. You can then easily email it or copy to the clipboard. ROT13 for iPad also includes spell check.
