Tracking your pet’s location and activity has never been easier thanks to smart tech like AirTag and Whistle. But which is better for keeping tabs on your furry friend? This in-depth guide compares the key features, benefits, drawbacks and use cases to help you decide.


Our pets are part of the family. So when they go missing, it’s incredibly stressful and emotional. Thankfully, GPS pet trackers like AirTag and Whistle make it easy to locate your cat or dog when they wander off.

Both options provide real-time location tracking, activity monitoring, and smart alerts. But they also have some significant differences in design, specs, integration and intended use. For example, AirTag faces stiff competition from trackers like ByteTagBaseusCube and Orbit.

As a pet owner and tech enthusiast, I’ve tested and compared both trackers hands-on. In this comprehensive guide, I’ll share my insights to help you choose the right pet tracker for your needs and budget.

Key Differences Between AirTag and Whistle GO

Tracking Network & GPS

  • AirTag uses Apple’s expansive Find My network of over 1 billion Apple devices to pinpoint your pet’s location. It does not have built-in GPS.
  • Whistle GO has both cellular GPS and WiFi tracking to provide location accurately independent of other devices.

Water Resistance

  • AirTag is splash and rain resistant but not fully waterproof.
  • Whistle GO is waterproof up to 3 feet for 30 minutes. Better for pets who love water.

Battery Life

  • AirTag battery lasts 1 year on CR2032 battery.
  • Whistle GO battery lasts about a week and needs regular charging.

Activity Tracking

  • AirTag only tracks location. Does not monitor activity or health.
  • Whistle GO tracks sleep, exercise, scratching and provides health alerts.


  • AirTag costs $29 for 1 or $99 for 4 pack.
  • Whistle GO costs $129.95 upfront + $9.95 monthly fee.

AirTag Benefits and Uses

Works With Find My Network

The AirTag taps into Apple’s massive Find My network of over 1 billion active devices. Whenever an Apple device comes within Bluetooth range of your lost AirTag, you’ll get an updated location on the Find My app. No need for cell service or standalone GPS.

Find My App

Affordable Upfront Cost

At just $29 for one AirTag or $99 for a four pack, the AirTag is one of the most affordable pet trackers available. There are no monthly fees or data plans required. Just the one-time cost of the device.

Lightweight and Compact

Weighing just 0.39 oz with a 1.26 inch diameter, the AirTag is extremely lightweight and easy to attach to a collar, harness or tag. It won’t weigh your pet down as other trackers might.

Seamless Setup for Apple Users

If you already use an iPhone, iPad or MacBook, setup takes seconds. Just pair with the Find My app and attach to your pet. No new accounts or apps needed.

Long Battery Life

The user replaceable CR2032 coin battery lasts for up to 1 year before needing replacement. Much longer than rechargeable trackers that need weekly charging.

Airtag's Battery

Works Internationally

Since AirTag taps into any nearby Apple device, it provides global tracking without international roaming fees or cell plans. Great for frequent travelers and adventurers.

Best Uses for AirTag Pet Tracking

The AirTag really shines for typical household pets who stay nearby home and don’t need constant monitoring. The affordable price point makes it easy to use AirTags to track multiple family pets.

Around-town Tracking

For suburban pets who roam around the neighborhood, AirTag provides ample tracking via nearby Apple devices. You’ll get alerts as soon as your pet leaves a designated safe zone.

Fitness Tracker Alternative

If you have an active, energetic pet who loves roaming and exploring, AirTag presents an affordable alternative to advanced fitness monitors while providing location visibility.

Emergencies Backup

Even pets with other smart collars can benefit from having an AirTag as a backup tracking option in case of dead batteries or faulty tech issues.

Multi-Pet Households

At $29 each, AirTags are budget-friendly enough to use for 2-3 household pets so you can monitor all their locations easily.

Infrequent Adventurers

For household pets who only have occasional outdoor adventures, AirTags provide location tracking without needing real-time health metrics and activity data.

AirTag Limitations

While AirTag excels at affordability and leveraging the Find My network, there are some limitations to consider:

No Standalone GPS

AirTag relies on being in Bluetooth proximity to iPhone and iPad devices. Without standalone GPS, tracking can be hit or miss in rural areas with sparse Find My network coverage.

Not Intended for Pets

AirTags are designed and optimized for tracking objects like keys and luggage. The hardware is not pet-proof and Apple provides limited pet safety features.

Short Anti-Stalking Window

To prevent unwanted tracking, AirTags alert unknown iPhones after 8-24 hours. This gives a very short window to find pets compared to other trackers.

No Fitness Tracking

AirTags only provide location information. There is no real-time activity monitoring, health tracking, or customizable safety alerts.

Limited Water Resistance

With an IP67 water resistance rating, AirTags can withstand splashes and rain, but are not designed for pets who play in lakes or pools.

Whistle GO Benefits & Uses

Whistle GO was designed from the ground up as an advanced health and fitness tracker for pets. It goes far beyond basic location, providing a comprehensive view of your pet’s activity and safety.

Whistle Smartphone App

Multi-Network Tracking

Whistle GO combines cellular data, WiFi, and Bluetooth to provide reliable GPS tracking anywhere nationwide. No dependency on a crowdsourced network.

Fitness & Health Monitoring

In addition to step counting and activity levels, Whistle GO tracks sleep, licking, scratching and other behaviors, sending alerts for potential health issues.

Whistle Health Monitoring

Waterproof Design

With an IPX7 waterproof rating, Whistle GO can be safely submerged in 3 feet of water for 30 minutes. Great for swimming and water play.

Custom Safety Alerts

Create customized safe zones and proximity alerts to be notified whenever your pet escapes a boundary or is on the move.

Veterinary Insights

Get personalized health insights, advice and next steps from Whistle’s vet team based on your pet’s monitored behaviors and activity.

Improved Battery Life

While not as long lasting as AirTag, the rechargeable Whistle GO battery still provides nearly a week of runtime between charges.

Best Uses for Whistle GO

Whistle GO shines when you need more than just location tracking. The advanced monitoring and alert system gives complete peace of mind for high-risk and health-prone pets.

Senior & Disabled Pets

Know when aging or mobility-challenged pets start slowing down or having issues. Adjust care plans accordingly.

High Health Risk

Monitor chronic licking, itching, limping or other problems and get professional advice early.

Extreme Adventurers

For pets who hike, swim, roam for miles, Whistle provides durable, real-time tracking.

Escapists & Wanderers

Pets who escape fenced yards or slip away off leash are quickly located before getting lost.

Hyperactive Breeds

Keep high energy pet breeds active and healthy while monitoring for signs of overexertion or exhaustion.

Whistle GO Limitations

While Whistle GO offers the most advanced tracking capabilities, the higher price tag and required subscription may make it prohibitive for some budgets.

Higher Upfront Cost

At $129.95 for the device alone, Whistle GO costs nearly 5X more than AirTag upfront. The subscription adds even more ongoing costs.

Monthly Fee Required

On top of the hardware cost, you have to pay $9.95 per month to keep cellular service and advanced features activated.

Shorter Battery Life

The rechargeable battery needs charging about once per week compared to AirTag’s once per year battery change.

Larger Size & Weight

Weighing 1.2 oz, Whistle GO is over 3X heavier than AirTag. The larger size may not suit smaller collars and harnesses.

More Complex App

With advanced health features comes a more complex app and dashboard. May provide more data than the average pet owner needs.

  • Lower risk pets can just use AirTag for location tracking

Your Budget

  • AirTag is great for pet owners on a tight budget

  • Position on collar where pet can’t lick or paw it off

Consider a Backup Tracker

  • Have two trackers on collar for redundancy
  • Use both AirTag and Whistle GO for optimal tracking

Enable Owner Info

  • Helps get pet home fast if found by good Samaritan

Take it Swimming

The Final Verdict

For most households with indoor/outdoor pets, the AirTag provides an affordable, easy-to-use location tracker leveraging Apple’s expansive Find My network. It’s a great basic option covering the core need of tracking your pet’s whereabouts.

However, for pets at higher risk due to age, health conditions or extreme activity levels, the advanced health monitoring and real-time GPS tracking of Whistle GO provides valuable peace of mind. While pricier, it provides benefits that extend well beyond basic location tracking to keep your pet safe and healthy.

Ultimately, there is no universally “best” pet tracker. It depends on your specific needs and priorities. By understanding the key strengths and limitations of both AirTag and Whistle GO, you can make an informed decision to find the right fit for you and your furry friend!
