EmberSeek
Room-by-room finder for your Bluetooth gear · iPhone
A live Bluetooth signal jumps around as you walk, which makes it hard to tell which room your earbuds are in. EmberSeek fixes that with Room Sweep: stand in each place for a few seconds, and it compares the median signal and ranks where to look first.
Up close, the Hot/Cold Finder guides you with a heat meter, haptic pulses and optional spoken “warmer, colder” cues, so you can search without looking at the screen. Gear Check tells you which of your saved things your iPhone can hear before you leave, and calibration tunes the meter to each device.
EmberSeek can only detect devices that are switched on, have battery left and are within Bluetooth range. Everything happens on your iPhone: no account, no server, no tracking.
