## Description

Dog Whistle is a free Chrome extension designed to assist you in training your dog using high frequency sounds. Humans can typically hear up to 20 kHz, but dogs have a superior hearing range that detects sounds well beyond this. This app emits sounds ranging from 100 Hz to 22,000 Hz, allowing you to produce silent signals that your dog can hear but you cannot. Ideal for dog training, these dog whistles provide an effective communication tool without disturbing humans. Remember to use the app responsibly, considering your dog's comfort and safety.

## Review summary

Overall, reviews show the app often works as a basic dog whistle and some users report good results, especially when adjusting the frequency.

Many also report inconsistent effectiveness across dogs, including instances where the dog did not respond or the app seemed to do nothing. A subset describe the app as garbage or a joke. The experience appears hit-or-miss, with usability hindered by advertising and reliability concerns.
