Had a bit of a scare with one of the children this morning so I thought it maybe wise to invest in one of the phone tracking services - would save my heart for sure 
So I had a quick google and they all seem to be subscription based - which is fine but then they limit the number of tracks done, which I hadn't expected.
Does anyone have any experience of these services and recommend. I also see that Google have the latitude service - how seamless is this, does it only work when they query google maps or can it work in the back group (internet use is not an issue if it is any good).
Any thoughts would be appretiated
