"Highster Mobile was my second try to get a working tracking app - yet it didn't ended well.
I have installed it on my Android, and it even managed to track its location pretty well.
However, app drained my battery rather quickly, which wasn't normal even according to their approximate estimations.
Aside from that, none or the features, except of the GPS tracking, seemed to work properly. In my case, this was the most important issue, therefore I quit them. Can't say nothing bad about their Refund system - it worked well - but in general it was pretty disappointing. "
