Know the difference.Track with confidence.
Not all trackers measure up. Fi gives real-time GPS tracking with no guesswork or gaps.
Microchips don’t track
Chipped dogs need to be safely brought to animal control or a vet for scanning. Fi always knows where they are.
AirTags aren’t meant for dogs
Limited waterproofing and short-range iPhone tracking fall short. Fi uses GPS to track your dog—no matter how far.
