I found it as additional safety feature, however not bullet proof, neither reliable. I have seen aircrafts appearing then disappearing from the screen, then mine doesn't start transmitting data out before ~700ft, then I had overheating issues..
Regardless, I have seen a number of aircrafts on the screen prior to identified them in the air, and I am sure many have seen me too.
Other than above, the integration with EFB's is looking "cool", providing some features found in $$$ expensive glass cockpit aircrafts..
Sorry for the poor photo quality.. That's Samsung Note 9 and SkyEcho 2 right above
