    Frequently asked questions

    Does the Whistle FIT Have a Subscription?

    Yes, the Whistle FIT does include a subscription. We offer an affordable yearly plan of $59.40 that renews automatically each year. The full amount is due at the time of activation

    How Long Does the Whistle FIT’s Battery Last?

    The Whistle FIT can lasts up two weeks on a single charge, making tracking your pet’s activity seamless. We recommend to charge at 25% or less, the app will notify you when the battery is low. Battery life is impacted by Wi-Fi strength & cellular coverage, depending on usage and environment. The FIT comes with a USB charger that brings your FIT back to full charge in about 90 minutes.

    How Does Whistle Calculate My Pet's Activity?

    Whistle uses a three-axis accelerometer to estimate the total amount of energy your pet uses each minute. We use that energy estimate to tell if your dog was resting, wandering around the house, or doing more vigorous activity like chasing squirrels or going on a walk.

    How does my Whistle Tracker Detect Health Insights?

    Whistle sensors take 150 measurements of your dog’s motion every second. Advanced behavior detection algorithms created by our research partners at Pet Insight Project help detect the unique movement signature of scratching and licking

    How Does Whistle Estimate How Far My Pet Has Traveled?

    Whistle uses a three-axis accelerometer to sense how much your pet is moving up to 50 times per second. We used the accelerometer data from walks by tens of thousands of different dogs using our Whistle accelerometer and created an algorithm to transform these acceleration measurements into a distance estimate.

    How do I purchase a replacement or upgrade my Whistle?

    If you’re an existing Whistle customer and already have a subscription plan, you can purchase a replacement or upgrade your current tracker by clicking [this link]. Thank you for continuing to be part of the Whistle family!

    Note: If you activate the tracker for a new pet, you’ll be able to choose a subscription plan through the app

    Do I need to have an AT&T Plan to use my Whistle?

    No, your Whistle tracker is like a miniature cell phone for your dog! As such, it requires its own cellular plan, but is separate from the plan you have for your own phone. Whistle leverages AT&T’s 4G network to provide you the greatest coverage and fastest response, but you don’t need to be an AT&T customer to use Whistle. Your 360 subscription plan takes care of the cellular connection, so you can keep on adventuring with no interruptions

    Honestly, wanted to wait a while until I wrote a review for this product due to the reviews I read. I honestly love this product. I have 1 and half old GSD and wanted to know if I was giving him too little or too much exercise or if I was giving too much food or not. This has given me clarity on that.
