Ask HN: Do you have any interest in this?

Alright, so I have this tiny web application I use for myself. The main page is just blank with a button in its middle.

When I click the button, a text message is sent to my phone. I use this to find it around the house, because I misplace it frequently.

It's meets a very personal niche, but I wondered if anyone else had a use for it. What do you say?
