Useful? – Find My Fitbit - Fitbit Finder For Lost Fitbits Review

I downloaded this for free, but not sure why this is even useful. Anyone can have their Bluetooth connection scan for a missing Fitbit. If it's not within 20 feet Bluetooth can't see it and neither could this app. I can't believe people pay for this app.
