Hushbark hears your dog bark and responds in the same second with a high-frequency whistle, then logs what happened so you can see the pattern.
A bundled sound classifier runs on your phone. No account, no server, and audio is never uploaded.
A rotating set of high-frequency whistles interrupts the bark, so your dog cannot tune out a single tone.
Every bark is timestamped with a clip and a likely trigger. Export a dated PDF report for a landlord, an HOA or a council.
Deterrent tones work line of sight, best within about 15 metres. They do not carry through walls or closed windows, and any dog can get used to them, which is why the whistles rotate. Treat it as a training aid, not a cure.
