Measure the bond between you and your dog

Synchrony uses wearable sensors and machine learning to objectively measure behavioral coordination—turning invisible progress into visible data.

The Problem

Every year, millions of dogs are labeled "stubborn" or "disobedient"—when they're actually anxious, confused, or struggling to connect.

Training progress is invisible. You can't measure what you can't see.
Existing wearables track steps and sleep—not the relationship between you and your dog.
Without objective data, trainers and owners are left guessing.

The Solution

Synchrony measures what matters: the real-time coordination between you and your dog. Not just activity—connection.

Dual wearable sensors capture movement from both handler and dog simultaneously.
On-device machine learning analyzes behavioral synchrony in real time.
You get objective insights into training progress, stress levels, and relationship quality.

How It's Different

This isn't another pet fitness tracker.

Other Wearables

  • Monitor only the dog
  • Generic activity metrics
  • Cloud-dependent processing

Synchrony

  • Measures behavioral coordination
  • Tracks the handler-dog dyad
  • Relationship-focused insights
  • Privacy-first edge processing

Built by a Trainer, Powered by Science

Synchrony is developed by Will Flower, a professional dog trainer with 15 years of hands-on experience helping dogs and their people communicate better.

After years of watching dogs labeled "stubborn" when they were actually anxious, Will set out to build what didn't exist: a tool that could objectively measure the relationship between handler and dog.

The result combines validated behavioral science, edge-deployed machine learning, and a deep understanding of what trainers and owners actually need.
