DGM- This app is hit and miss. It is not accurate 90 percent of the time. The time frame they say you where at a location is not correct. The streets are not correct 75 percent of the time. I would not use this app to check on anyone with any accuracy. In the end it will end up messing your relationships up with inaccurate data. I dont know if the pay app is any better. I guess the old adage is correct. You get what you pay for. Or in this case what you dont pay for.
