Overview of Whistle Pet Trackers

Whistle Go Explore

Founded in 2012, Whistle is a San Francisco-based company dedicated to developing innovative smart technology for pets. Their product lineup includes both GPS-enabled trackers focused on location monitoring and activity monitors without GPS to track daily exercise and rest.

Whistle offers two main GPS tracker models:

  • Whistle GO Explore – The latest flagship model offering the most advanced features. Includes both GPS tracking and activity monitoring.

How Whistle GPS Trackers Work

Whistle GPS trackers use a combination of GPS, cellular data, WiFi, and Bluetooth to pinpoint your pet’s location and send updates to your smartphone.

Here’s an overview of how the technology works together:

  • GPS provides active tracking to follow your pet’s movement in real-time when they leave a designated safe zone.
  • Cellular data on the built-in SIM card transfers location pings from the tracker to Whistle’s app. No pairing required.
  • WiFi establishes safe zones around your home network so you’re notified if your pet wanders off.
  • Bluetooth connects the tracker to your phone during setup. Not used for active tracking.

Once connected to the Whistle app, you can track your pet on demand or get alerts when they leave a safe zone. Location updates are provided every 60 seconds while tracking.
