The mobile app is free but a subscription is required to setup the device

Just download the free Whistle mobile app to your iOS or Android smartphone and stay connected to your pet from wherever you are.

Please make sure to download the Whistle app with the green logo and white background. 

Once you download the app and begin setup you'll be required to select a subscription plan for your Whistle so that it can use AT&T's cellular network. 

Check out our video walkthrough of the setup process here:
