ADDED: You can now center focus the map on your location, in addition to a few more improvements to map interactions.
ADDED: Owners will multiple pets can now use an All Pets button to return to viewing all of your pets in the Maps drawer.
ADDED: We’ve improved the battery status indicators by adding them to the Maps screen, and displaying the battery life in percentage charged is now viewable on the Maps screen for our Tagg / Whistle GPS customers.
ADDED: New Maps button on your pet’s profile screen for quick access to view their location.
FIXED: We’ve listened to user feedback to make critical improvements to usability throughout the app.
FIXED: In the previous version of the app, there was no visual indicator for a locations request, so many users weren’t sure if the “Refresh GPS” request had worked. We’ll now show you that we are updating the location at the top of the screen so you know that the app is searching for a new location.

Whistle gps and activity works!

I love the integration of the activity tracker and the GPS. I used the whistle activity tracker app previously, I was really happy with being able to see how active my dogs were. It also helped track how active I was with them! We do have an escape artist dog, so I was really glad to be able to get the integrated unit. I can now see exactly where my dogs are. And know if they go outside of the designated zone, which in our case is a very large yard area. I didn't want to have to make a choice between a fit bit type activity tracker and a GPS tracker, so this integration is awesome. I understand battery life issues and appreciate the charging and power saving mode when the dogs are in the house near the unit. Eventually I'd love to be able to track our dog's walk and not only see how much activity they get and where they're located, but a history of their journey, along the lines of "map my ride "which is used for cycling. Set up was straight forward and the app works great. I see the dogs haven't had much exercise yet today so I'm grabbing a ball and heading outside with them!

Best app for your pet!

We love this app and our Whistle GPS Pet Tracker! We live in Alaska, and we were amazed to find a GPS product for our pet that works so accurately up here. We do a lot of hiking, and we have been so pleased with the layer of security that the app/tracker gives us. It allows us to keep our pet safe while still allowing him to explore the wide open spaces that Alaska has to offer. Even when walking on isolated trails, we have been able to locate our pet using the maps on the app. The activity tracking has really helped us to improve our pet's health! We have cold winters with very few daylight hours, and the app/tracker helps us make sure our pup is getting enough exercise each day. We love the graphs of our pet's activity throughout the day! The app is very easy to navigate and is so user-friendly, and Whistle's support team is fantastic. We would highly recommend this product to any pet owner!

Very disappointed

If I could give this less than one star I would. I was a tag user of 3 years and am so extremely disappointed with whistle. It is a million steps behind what Tagg was and is very hard to use. The sole purpose I got my dogs trackers was to easily find them if they ever get away from me and this app and system makes that nearly impossible. It takes 10 plus minutes to update you on the dogs location and the location it gives is inaccurate. The GPS portion of this has all kinds of bugs, is very slow and does not give the correction location. They have turned this into social media for dogs which I really don't care about. I liked Tagg because it did the job it was created for very well, and the whistle system is beyond terrible. Oh and to top it all off they just charged me a monthly service fee after I have already paid $95 for a year. I no longer have peace of mind when I have to leave my dogs with someone else like I did with Tagg. This system does a terrible job and is very very very hard to use and not user friendly. So disappointing.
