Is a loud beeper or app-based tracker better for finding keys around the house?

For pure in-home use with no smartphone dependency, a simple RF key finder with a dedicated remote (like the Reyke) is faster and louder than any Bluetooth tag — you press a button, the fob beeps at 80+ dB. Bluetooth trackers add value when you also need out-of-home recovery via a crowd-sourced network, which RF finders cannot do.
