The RemoteLync "Arm by Location" most definitely works for multiple users.

To make it work you need to install the RemoteLync app on the mobile device (iOS or Android) of each of the users who will be using "Arm by Location". Each of these users will need their own (free) RemoteLync account.  RemoteLync will track geolocation for each mobile device and will only arm when it detects that all devices have left the "Arm by Location" area.

By way of example, if Tom leaves the house at 8am and Jane leaves at 10am then RemoteLync will arm when it detects that Jane has left the house.   Later on, when RemoteLync detects that either Tom or Jane has returned to the "Arm by Location" area, it will immediately disarm.
