A few weeks ago, I lost my bluetooth earbuds in my house somewhere. It was still connected and nowhere to be found.

In my case, it wasn't able to come up with it, but fortunately I was, and had it build a local webpage that does "hot or cold" with a 0-100 score. And it worked first try! Found them in like 2-minutes.

Also made for a fun day of hot-and-cold hide-and-seek games with my niece after i had it built that concept as a sideloaded ipad app :)
