This is the best kind of startup - targeting an important problem whose current solutions are outdated and not very good.
There are LOTS of seniors already using such a product (usually ordered by their concerned family), and a low monthly fee is not an issue when your loved ones's life is at stake.
The existing solutions are basically a DECT cordless phone with a one-button 911 call. Marketing something like amulyte should be a slam-dunk. Of course you're not gonna sell "it has GPS and an accelerometer" - you market "it will notice when you fall, it will automatically call for help, even if should be unconscious, and even tell people where exactly you are".
