If I have one app, that uses global variable to save and write out data to screens.
And open that app on one phone, and do stuff in the app like save a timestamp or so.
Can I then be able to open that app in a second phone and take part of what the first phone do and the resault of what the first phone do in the app?
Example.
Phone one use the app and press a button on a timer so the timer starts, and later phone one change a value in a input from 0 to 100.
And then phone one press a button to get to second screen in the app, and on the second screen the timer is visible and the input changes that we made on first screen are visible via global variables.
Is it then possible to open the same app on phone two, and then take part and be on the same screen as phone one is? And see the input changes that phone one did and see them on phone 2.
