TL;DR – Is The Whistle 3 Worth It?

For most owners who want to track their pet’s location within the US, or monitor their activity levels within the last 24 hours, yes, it is worth it.

Most of the feedback on the Whistle 3 is positive, and it’s very popular. Whistle also seem to provide good customer service and are responsive to questions or issues you may have with using the system.

So, overall the positives outweigh the negatives.

The biggest pain points that some customers seem to have are:

– paying for the compulsory AT&T plan for the device

– manual tracking not working consistently sometimes when a pet is outside of WiFi range. This could be an issue with AT&T reception in their area, or an issue with the software/app itself, but it not a common issue to all users

– the battery not lasting as long as some owners would like (but on average you’ll get 2 to 7 days depending on use)

What Are Some Of The Cons And Drawbacks Of The Whistle 3 Pet Tracker?

If you have no AT&T service, or inconsistent AT&T service in your area, you may experience troubles tracking the location of your pet outside of WiFi range

The location tracking as of right now (March 2018) is not live tracking because the battery would drain too quickly

The app doesn’t update as quickly as some owners would like – it auto syncs every 3 to 6 minutes. But you can manually press the track button every minute

There is sometimes issues with the app displaying ‘having troubles tracking right now’ when some owners are trying to track their pet outside of WiFi range. If this happens to you, you’ll need to contact customer support to try to find a solution

Whistle’s customer service is usually good, but as of right now, they aren’t 24 hours support

You can only view your pet’s activity for the last 24 hours. 

You can only choose one pet to assign the tracker to. You need an additional Whistle 3 tracker and subscription for each additional pet.

The AT&T subscription you get is for the Whistle 3 device, and not for your mobile phone. You mobile phone cell data plan is separate

You may experience a shorter battery life if the WiFi range in your area is poor

You may experience a shorter battery life if cell reception in your area is poor

You may experience a shorter battery life if you are continually using the app to draw data from the tracker device


Overall, the device itself is good, but the software could be more reliable, more responsive and more improved in a few areas.
