Location Sentry is a tweak available since last night in Cydia, and with its help we can view in the task switcher the applications that use GPS to provide information about our locations. As you can already see from the image above, each application of the task switcher will have an icon displayed above it to let us understand that it uses GPS to retrieve information about our location, this being the only functionality of Location Sentry.
Location Sentry it is available for free in the repo BigBoss al Cydia.
