Fi Tracker
  • Submitted By Geoffrey Stanley on 12/10/2019
    The thing I like most about this app is that it has its own app where you can track your dog’s movement easily and without confusion. I’m not good with tech so it’s really important that know what I’m doing and fi tracker app made it easy. Another thing I like is that is not state limited so I can use it even when I take my dog traveling. We went hiking when we were at my boyfriend’s parents in Colorado and the app worked all the way even when we were high up and without a strong signal. I feel safe knowing my Penny is well taken care of.

    I very satisfied with the tracker except for the collar which didn’t last that long. I have two dogs one of them being very active. He likes to chew everything most of all his brother’s collar. Every time we go out both of my dog get very excited and while Ben knows how to sit down and wait for the leash, Roger gets unbearable while he jumps up and down and keeps biting his brother’s collar. Long story short the collar is all chewed up and has to be replaced. I was hoping it could withstand more.

    This Fi tracker is the best thing that has happened to me! My buddy and I take long walks around to the lake almost every day. He loves jumping into the water even when it’s cold outside and this tracker seems to be handling it very well. For me the battery lasted more than a month and a half and gps work even in the remote areas where coverage is not that good. The app is easy to read and it has the lost dog mode which is immediately activated in case anything bad happens. I feel much better ever since my dog started wearing it.

    I always wondered what would I do if Charlie, that’s my dog, would to run away when we were traveling. I would love to take him anywhere with me but I don’t know how he’ll react to new environments so I leave him with my mom and dad mostly. And it was tearing my heart. I did a little research and found that Fi Tracker enables whole country coverage in case you and your pet leave the state. I’ve recently bought it I was amazed by how long the battery lasts, I didn’t need to charge it yet and it has been almost a month. Finally, I was able to take Charlie on a road trip, we went to see my parents is Vioming for a test drive. I was tracking our movement on the app the whole time we were there. Couldn’t be happier!

    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.
  • Submitted By Jenna Simmons on 05/07/2019
    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.
  • Submitted By Patric Small on 04/05/2019
    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.
