This application can be used to monitor or find missing Bluetooth devices - like your Fitbit or other smart bracelet wristband or watch.
It can also be used to debug bluetooth connectivity problems. It will measure the signal strength of nearby Bluetooth devices then display the dBm readout and show a convenient line graph of the signal strength. It will also show the MAC address of the device - and the name of course.

Please notice that signal updates can take 15 seconds up to 1 minute depending on the Bluetooth hardware and conditions. Some patience may
be required when using this application.

Some devices will not be detected when connected and some must be in discovery mode before they will be detected by this app - like some BT Headsets.
