Unless I'm missing something, to find your keys etc , you can use the phone to find them using Bluetooth SO LONG AS THE ITAG IS ON. To find your phone when you have your keys, you need your phone on AND BLUETOOTH ON. You actually need the phone to turn on the ITAG and the ITAG to turn on the phone and Bluetooth. Otherwise best case you use up the ITAG battery for having it on all the time and your phone batt for having Bluetooth on all the time. The App seems to work fine subject to those limitations.
I'm using iTracing2 with generic iTag devices, very cheap from ebay. My main purpose is to have a personal/trusted Bluetooth device that my phone detects. My phone is a 2012 Galaxy Note 2 running KitKat and Xposed Framework with "No Lock Home" module. On my home WiFi "No Lock Home" disables the PIN protected lockscreen. It can do the same task if associated with a known Bluetooth device by MAC address. So I found my iTag MAC address by using the app "Bluetooth Address Finder" and then I can use iTracing2's "foreground mode" and this keeps the link alive and so long as my iTag is nearby then my Phone remains unlocked when away from home on 4G/3G etc. iTracing2's foreground mode is excellent. It does maintain the connection but it does not prevent the phone from sleeping. By using a few free apps and buying a £2 generic iTag I get a sophisticated "Smart Lock" system while retaining the ability to use SSL certs, VPN and so on. 2012 Galaxy Note 2 lives another year! Only H.265 will deprecate this beast. This is an app that works as described, does so without requiring intrusive extra permissions, and is easy to understand and to personalise. Ideal!
This actually works with my iTag. Nothing fancy, but it has a button to make the tag beep. However, the device also beeps whenever the phone loses the connection - good for not forgetting keys, but bad for finding pets.
The 'iTag beep' option does not work: 'something goes wrong!' message. It means that the iTag starts beeping regardless on the setting once the bluetooth is disconnected
You can track the itag and it will make the itag beep to find it. You can also use the itag to find your phone. A maps locator would be great to add to the app.
This app was brilliant on my HTC, better than the software that came with my tag, but there seems to be an issue with Honor 8 where it keeps turning off/disconnecting even though it's set to stay on.
