Very useful – GPS TRACKER:Real-time tracking Review

Have a family member backpack in Asia shortly and am hoping to have tracking as an added safety mechanism. Trying it out and good so far. Read reviews here complaining of the need to keep the app open, to refresh, etc. But what is wrong with that? Will write a detailed review after using the paid version.
