How do you link the same app on two different phones?

Hello, can you help me. How can I link the information, with the same app, that passes from one to the other. For example, how can I transfer the GPS location that I have on one mobile phone to another, to know where it can be found at any time. That is, the information is transferred to another screen and updated every 30 seconds. Localizame.aia (254.1 KB)
