Just read my Time Magazine and this article was in it.
This smartphone app erases messages in a pre-set time. So if you text a love message to someone not your significant other...you can make it erase itself in 60 seconds to 5 days. No trace remains on the phone or servers and the only way to save it would be to take a picture of it.
The makers of the app are now attempting a photo erasure program in case you send a photo you regret. Apparently this app has gone viral.

But company execs insist TigerText was not created with philanderers in mind; they say the name was chosen to invoke tigers' stealth, before the Woods brouhaha.
