Trying to diagnose why our watch isn't connecting to other apps that have a more aesthetically pleasing interface like Samsung Health and other generic watch apps we still can't see the watch. Tapping the build number took us to the settings but the language barrier made us appreciate other brands.

So far it seems like it could be quite a useful tool. Still trying to figure it out. Would be nice if I could lable known devices and categorize them to make the data easier to parse. I know there's tutorials, but the webpage link is broken. Somebody should sort that out. I can find it probably if I poke around the site a bit, but it's a bit unwieldy, and I went down a different path and got distracted

Worked great for my needs. We've had heat pumps installed in our town homes. Setting the app for them has been difficult. That apps search function returns Bluetooth data, but that data isn't on the interior heads, so finding yours out of the dozen or more found is difficult. This app gives me the required info and signal strength to identify which are mine and in which room. If you have a Bluetooth signal issue, try this app.

Scans forever and find nothing. Double verified to accept settings after reply. It doesn't work.

Absolutely USELESS if you can't rename BT devices
★★☆☆☆Paresh Patel· Nov 16, 2025
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
