Thanks for the heads up. Yeah, I'd seen finder, although there are a couple of problems: 1. It hasn't been updated for almost a year. Not sure, but it's looking like development may be dead. 2. This helps find a phone. What I'm looking for is something that can let me find my keys, using a phone. This needs small hardware. Hardware which sadly, only seems to exist in the form of proprietary hardware linked to surveillance software.

That's why I suggested this usecase.
