The new Whistle app only supports the latest Whistle 3 GPS location & activity tracker and Whistle FIT (in partnership with Banfield Pet Hospital).

Introducing the new Whistle 3, our latest all-in-one GPS location & activity tracker for dogs & cats. The new Whistle 3 app has been completely redesigned based on real-life user experiences with pet loss and activity tracking.

*denotes W3 only feature

• Location Tracking* •

Fast, accurate tracking with GPS, Wi-Fi and cellular technology to find your pet in minutes if they get away (now with Google maps).

• Breach Alerts* •

Get an email, app or text notification when your pet leaves their safe place, before they get too far.

• Multiple Custom Safe Places* •

The app's improved geo-fencing feature means pet owners can now create multiple safe places for the home, office, or a dog-friendly vacation spot (Wi-Fi is recommended).

• Track Activity •

Track your pet’s daily activity, distance, caloric burn and rest to keep your companion in great shape for their age, weight and breed.

• Set & Manage Goals •

Set custom goals and receive notifications if there are significant changes to your pet’s activity or sleep patterns.

Whistle setup requires a working internet connection, Wi-Fi, and Bluetooth. iOS 10 or newer is required. Continued use of GPS running in the background can dramatically decrease battery life.

Note: If you have a Whistle FIT and would like to upgrade to the GPS enabled Whistle 3, please contact us at support@whistle.com.

Wonderful improvement!


The older pet tracker versions that Whistle offered were good, but the new Whistle 3 adds some well-thought-out improvements. The app is a bit more user-friendly, but the important improvements are in the device. It is smaller, lighter and more responsive than the older models. Plus, the home boundaries can be easily set in the app to match the property line - or any other dimension if you want. For me, this means that if my pet steps off the property I quickly get a notification. In my area, the coverage with AT&T is much better than the Verizon coverage on the old service and I get notifications much faster now. The notifications are more precise, too. They say my dog is “300 feet from home near 1234 Elm St.” I live in the city, so the faster, more precise notification could be a live saver. The only weakness, if I can call if that, is that when spending a great amount of time away from home (where battery power is saved by using WIFI), the battery life is less. But, Whistle notifies you when the battery is low and it can be recharged quickly while my dog naps. Last, but not least - Whistle support is wonderful. I have had their products for several years and they are helpful and very easy to deal with.

Great App & Pet Tracker

I previously had another brand of Pet Tracker and this one was recommended to me. I have used it for 3 weeks and it’s great. The app is great, and the battery life far exceeds their 6-10 day website expectations. I have used the device for 15 full days and the battery is on 61%. I think I will get about 30 days out of the battery before having to recharge. Our dog is at the house most of the time, so it’s in WiFi range and goes on a walk once a day. I have the GPS poll time set to 3 minutes (fastest option) so we get detailed route maps.

The only thing I would like to see improved is the live tracking should be faster. Live tracking is only a location refresh every 60-90 seconds for me in full cell signal areas. I hope with time and updates this will be much faster.

If you have everything that they don’t tell you

I have Springer’s and they like to put their nose down to the ground and wonder. At first I was pleased I tracked my dogs for six hours on a three thousand acres reserve and caught them right as they came out on the highway. Second time they went out at 8 Am and 8 pm they were still out but battery life was fading. Plotter on tracker phone was still. Didn’t know if the dog got killed or he lost device. Next morning still gone when to last location and nothing. Five that afternoon and five miles farther a friend call me on the phone said he had them. But due to the tracker but name tags with my phone numbers. A far piece from seven to nine days to ten hours. Did not have 3 g nor a Yfy and that was the reason for it not working properly. Works great when battery is still good. Going to keep item just in case things change
