Whistle
  • Submitted By Tim Grady on 11/20/2019
    I’ve noticed that it doesn’t work very good once it’s not within our home’s wifi zone. Sometimes we go camping and there’s almost no cell reception there so we have problems receiving any data at all. But when we are at home the thing works perfectly. It’s fast and accurate and charge it one a week. Once Stella ran away from my daughter when she saw the neighbours can and my daughter didn’t manage to come home and tell us that for about 5 minutes but I already knew since I got notified and we found stella exactly where the app pinpointed the location within a few minutes standing under the tree, barking at the cat.

    Tracy used to wander away from our yard and end up in our neighbour’s yard playing with their dog so to be able to track her down and immediately get notified when she escapes is what matters the most. With whistle I can set up a perimiter where she’s allowed to go and get notified once she leaves that space. It saves me lots of time and worrying when she leaves the yard and when I’m not home I just text the resto of the family where to pick her up.

    I love that this app works as any other activity app I use. You simply download it to your phone and use it like any other where you get to see the history and set up goals once you enter your dog’s information. I share Donna’s activity date with my husband so we can know how much exercise she has that day and dont overdo it.

    This was my tracker of choice because it functions as both tracker and activity monitor. As a family we are passionate hikers so being able to track our Tom’s vitals is very important to us especially since he’s an older dog. The thing I also like is that you have constant coverage because is connected with you phone all you need to do is download the app. You can connect through bluetooth and use your home’s wifi. The cell network is AT&T and if you don’t have wifi you can track your dog as long as the area is covered by the network. And when the signal is strong the coverage precision is really good. We didn’t go anywhere so far were the signal isn’t strong so I don’t know how it works in those places.

    This app is like a treasure map seriously. It was really the worst case scenario for me when my dog got away from our yard one time because someone left the gate open. I was able to track him down in 10 minutes, would be faster if I noticed right away, by following the route that was mapped in the app. All I did was follow the path that was provided by the app and found Max just down the road getting treats from the neighbour who recognized him and kept him occupied and well fed while I was on my way.

    I think it needs more powerful battery since the one it has only lasts for 12 hours and less if you use it constantly with live tracker on. In case your dog really does get lost, the battery won’t hold for too long and you won’t be able to find your pet after that. Luckily the live tracking feature is really precise and you should be able to find your dog quickly in case it runs away or gets lost and the good thing is you can instal the app on any phone so locating your lost pup should be a piece of cake.
  • Submitted By Tamsin Flowers on 11/28/2019
    This tracker is lite and nice looking. It is easily adjustable to the dogs collar and you can carry your device on yourself in your wallet or anywhere else because it fits. I like that you hardly notice it is there except when you need it and it doesn’t bother either you or your pet. My dog moves freely around and I didn’t see him trying to take it down or anything. I’m relieved because otherwise he would scratch all the time trying to take it off and he would probably do it at some point and lose it somewhere. And I read that it is tough to break or damage so that’s a plus
  • Submitted By Tracy Adams on 11/24/2019
    You can connect your part of the tracker through bluetooth to see where your dog’s at at all times. You can see where he goes and the tracker sends you a notification if your dog goes out of the safe place which is a limited space you created he can move around freely. In case your dog leaves this place you will be able to follow him on your app so he doesn’t get lost. The tracking range is not limited for example I don’t need cell signal to work the app, it can function without it because it uses another technology which can work anywhere and doesn’t cost a penny.
