PearCircle shares your live location with your circles. For that to keep working when you put the phone in your pocket, the OS needs permission to run PearCircle in the background and to read location while the app is not in the foreground.
Two permissions matter:
Without both, your pin goes stale as soon as you leave the app.
On first launch, PearCircle explains why background location is needed before the system dialog appears. Choose Always when prompted.
If you previously chose "While Using" or denied:
iOS will occasionally ask you to confirm that you still want PearCircle to use background location. Tap "Always Allow" when this appears, otherwise iOS silently downgrades to foreground-only.
Focus modes and Low Power Mode can suppress background activity. If sharing stutters, check whether a Focus or Low Power is on.
On first launch, PearCircle explains why background location is needed before the system dialog appears.
If you previously declined, open Settings, Apps, PearCircle, Permissions, Location and set to "Allow all the time" with precise location enabled. PearCircle shows an in-app banner that deep-links to this screen.
Many Android phones aggressively stop background apps to save battery. If PearCircle keeps going to sleep, exclude it from battery optimization:
After changing these settings, reboot the device and confirm your pin keeps updating on another circle member's map while PearCircle is in the background.
The quickest end to end test:
If your pin only updates when PearCircle is foregrounded, return to the permission and battery steps above. A reboot after changing battery whitelist settings is often required for the change to take effect.
