Phantom 3 connection to phone.

I have a phantom 3 drone standard. My daughter had an app on her phone where you could see the camera footage as you were flying it but it seems we can no longer find that app. She says that they are no longer supporting that but I’m not sure if that is correct. What app should I go get and download onto my phone so that I can see through the camera lenses I’m flying the drone? Thanks for any help.

You’ll need DJI GO (version 3).
