How to see the moving track of another mobile phone in one mobile phone?

Only when both parties have installed the same location application can they see the movement track of the other party's mobile phone.

For example, homesickness can look at each other's latest position and action track.

Usage: Both parties install and log in the same account, and follow the instructions on the software.

Precautions:

1, monitoring requires the owner's permission.

2. The monitored mobile phone must be set to run in the background (described) to prevent it from being automatically cleaned by the mobile phone system after the screen is locked.
