Train your dog, make him stay alert, stop barking or get him to come back with this fresh new app, Dog Whistle PRO. Built with modern and innovative controls, you can control ultrasonic sounds humans can't hear (but your dog can) easily using 3D Touch Technology.
As hard as you press the screen, intensity and frequency will increase accordingly, with the generated sound audible up to 3km away from you. There's 4 frequencies available and integrated with haptic feedback.
And if you have an Apple Watch, you can control it remotely too, changing levels by just spinning your Digital Crown!
