Fig. 01 — The app itself
Fig. 02 — How the collar speaks to the dog

From a whistle to a boundary alert. The owner chooses the level in the app, which is why the training content and the hardware had to be understood as one product.

Constraint, then decision
GPS holds in some places and drifts in others
I walked real routes with my own dog on an early prototype. The interface never promises more precision than the signal delivers.
The collar is set up, paired and updated only through the app
Every setup step delays the first working fence, so each screen had to justify itself against that one moment.
The training content is the differentiator, and it was a 15-minute gate
The videos stayed in the product, one tap away, and stopped standing in front of it.
Fig. 04 — What the app has to carry

Live tracking
Live GPS tracking updates 4x per second in the app, more than any other tracker or GPS fence.

Auto protection
Halo protects your dog automatically — even without your phone nearby — and notifies you when they approach their boundary.

Activity tracking
Logs walks and tracks daily activity so you’re always connected to your dog’s health.
Three things the collar does on its own, and every one of them has to be readable on a phone held in one hand. That is the surface the setup flow leads into.
