was pretty good until i upgraded my phone. now i have to keep my old phone with me as the app says it isnt compatible with a 2017 Moto C. sort that out and i will increase the stars. until then its 1 star as it doesnt work. i sent a message to them and they said i had to contact the PHONE manufacturer!!!!! its NOT the Phone manufacturer who produces the app! classic case of only making it work on the phones that the developers WANT people to buy, rather than what they can afford! 2022 edit. now got the app working on my phone BUT now location wont work for being able to locate the kids WITHOUT a data signal. theyre too young to be trusted with internet access without PARENTAL supervision. and surely the biggest tech giant in the world, GOOGLE, can take GPS location and translate it onto google maps? after all im sure theyre doing it for their OWN gains, so why not parents benefit also?
