Peace of mind knowing where you cat is, while really interesting tracking their territory. Really easy to use App with a variety of options. You can change how often your pet is tracked, whether you see a heat spot for duration of stay, or lines of travel or just a blob with the actual time they were there. I now know all his favourite haunts and when he is liable to be there. Needless to say, being a cat he is mostly asleep, but its good to know which sunny spot he is in. We have had this for months, still on the original collar clip and only had a couple of App blips which didn't last long. I have the app on my mobile but not sure if you could use it on a laptop, but the only downside is if you don't have a mobile phone. When you really need to hunt your pet down, you use your mobile as a hotspot for wifi and use the charging hub, which has an aerial, to go out and find your pet from the last point on the app. The app alone may not home in enough to find your pet.
