Dog Whistle Stop Barking

Dog Whistle is a professional training app with high-frequency ultrasonic sounds, automatic bark detection, and a training clicker soundboard.

🎵 ULTRASONIC WHISTLE
Adjust the frequency slider from audible tones up to 22 kHz ultrasonic — silent to human ears but highly audible to dogs. Choose from six quick frequency presets (8k, 12k, 15k, 17.4k, 20k, 22 kHz) or enter exact Hz values. Use sound patterns like continuous, warble, beep, or pulse/SOS for different commands.

🛡️ BARK GUARD (AUTO DETERRENT)
Bark Guard listens using your microphone and automatically triggers an ultrasonic tone when it detects barking above your set volume threshold. Customize sensitivity (50-100 dB) and deterrent frequency. Tracks session and total barks with a 1.5s cooldown to prevent self-triggering.

🔍 FREQUENCY FINDER
Not sure which pitch your dog responds to? Frequency Finder sweeps the frequency spectrum automatically every 2 seconds. Tap "reacted" to bookmark their pitch so you can use it instantly next time.

⚡ HUMANE ESCALATION MODE
No-shock progressive correction sequence: a soft warning tone, rapid pulse-beeps, then tone plus haptic vibrations.

🎵 TRAINING SOUNDBOARD (11 CUES)
Quick attention and recall sounds: clicker, high clicker, squeak toy, chirp attention cue, bird, cat meow, pager vibration alert, attention beep, pulse train, white noise rustle, and 20 kHz silent recall loop.
