Fi Dog Collar VS Whistle Tracker – HONEST Review

Do you ever feel like you’re constantly worrying about your pet? Maybe you can’t shake the feeling that they’re always getting themselves into trouble.

GPS pet trackers are becoming more popular and for a good reason – they help you track down your dog if they get lost or leaves the yard.

In this post, we’ll compare the Fi Dog Collar vs Whistle tracker to decide which one is right for you and your best friend.

Introduction to GPS Pet Trackers

Fi Dog Collar Vs Whistle: Which GPS Pet Tracker Is Better
Both the Fi Collar and the Whistle can track the location of your dog via GPS and monitor your dog’s activity and health levels.

GPS technology has revolutionized the pet tracking industry in recent years. Gone are the days of bulky, uncomfortable collars with large tracking devices.

Now, sleek, lightweight options use GPS to track your pet’s location in real-time.

Two of the most popular GPS pet trackers on the market are the Fi Dog Collar and the Whistle GPS Pet Tracker.

The Fi Dog Collar is a versatile option that can be used for both dogs and cats.

It uses GPS to track your pet’s location and activity level, and it also includes a built-in SIM card that sends you notifications if your pet leaves a designated safe area.

The Whistle GPS Pet Tracker is another popular option that uses GPS to track your pet’s location.

It also includes a fitness tracker to monitor your pet’s activity level and a feature that notifies you via text and app notification if they wander too far away.

The Whistle GPS dog tracker was also made to be a health tracker.

Fi Dog Collar Vs Whistle Tracker Compared

A Comparison of the Fi Dog Collar and Whistle GPS Pet Tracker
The Fi collar is only available in a collar/tracker combo while the Whistle offers a collar/tracker combo and an individual tracker that you can use on your dog’s existing collar.

Fi is a GPS pet tracker that attaches to your dog’s collar and uses a cellular connection to track its location.

The company offers two subscription plans, with the more expensive one including real-time tracking, an LED light, and temperature monitoring.

The Whistle is another GPS pet tracker that also uses a cellular connection to track your pet’s location.

It has a few extra features, such as activity tracking, a safety zone feature, and the option to set up multiple users to help keep an eye on and locate your dog.

So, which collar is right for you and your pet?

Battery Life

Our tests show that the battery life on the Fi Dog Collar lasts for several days, depending on how often your dog moves around.

One of the great things about the Fi Dog Collar is that the Fi Collar instructions are super easy to follow for setup.

All you need to do is attach the collar to your dog’s existing collar and download the app on your phone to connect the two.

Meanwhile, we found that the battery life on the Whistle GPS Pet Tracker lasts up to 7 to 10 days, again depending on how active your dog is.

Location Tracking

GPS Pet Tracker
The Fi and Whistle trackers both offer activity monitoring and location tracking.

When it comes to features, both the Fi Dog Collar and Whistle GPS Pet Tracker offer basic location tracking as well as some additional bells and whistles.

With either device, you will be able to see where your dog is at any given time and where they have been over the past 24 hours (or longer).

However, only the more expensive subscription plan from Fi includes real-time tracking.

Fi’s real-time tracking updates your dog’s location every few seconds instead of just once per minute, like with standard basic location tracking.

Activity Tracking

Both devices use built-in accelerometers to track how many steps your dog takes each day and how much time they spend running, walking, and playing.

This information can be helpful if you are trying to ensure your dog is getting enough exercise.

Safety Zones

Another feature that both devices offer is called “safety zones.”

With this feature, you can create a virtual fence around your home or yard so that you will be alerted if your dog leaves the area.

Both devices also allow you to set up multiple user accounts so that other people who need to track your pet – like friends or family members – can do so easily.

You can add all of your pets to the Whistle and Fi apps to keep tabs on your pack! Each will have its own profile.
