Using the Angel Watch app, you can set the watch to acquire the users location every 10 minutes, 1 hour or fetch the location manually from the Angel Watch app on-demand.
On Android, it will show the following 3 options:
Sleep Mode - Manually obtain position (Default)
Power Saving Mode - Updates every Hour
Normal Mode - Update every 10 min
On iOS, it will show the following 3 options:
Power Saving - On Demand Position (Default)
Everyday Mode - Update every hour
Outodoor Mode - Update every 10 minutes
Frequent updating uses more battery life, so it's best to use the appropriate setting for the scenario. e.g. set manual while at home, update to every 10 minutes when out in the park.  You can change this at the push of a button anytime on the Angel Watch app.
