Ratings and reviews

unable to view the bluetooth keyboard in the scan list, whereas other bluetooth apps or system apps easily detects the bt keyboard with name. the bluetooth keyboard is old with bt v3.x

Excellent app with no ads. Some suggestions: Add a filter for manufacturer keywords, both show only and hide. Also add an option to show devices with randomized MAC addresses as one device. I love the app. ♥️ Great work.

omg! i rarely take time out rate apps. fantastic.
