Im one of the developers of Get Console - the best Serial Terminal app for iPad (we think..). I do other stuff as well, but mainly CCIE network geeky stuff.
@KarlAustin you can make it more secure by configuring Serial->Advanced settings. The tension between security and ease of use - we go for the later out of the box as reduces support issues, but you can make it more secure of course.
@mattouellette@LukeoftheTauri you should check out our new Airconsole LE then - lasts for 6 months on 1 battery :) https://t.co/3jFNhcdqUm shamless plug!
