Stop Annoying Ads by Disconnecting WiFi/Data – Dog Whistle to Train Your Dog Review

The free version has terribly annoying ads frequently interrupting the operation of the frequency sound generator so you can ether pay to have the ads removed or disconnect your device from wifi/data and the ads cannot load. You may notice one ad slip through for it was previously downloaded but once that one is finished, you shouldn’t have to deal with any others. Take note that this app may be generating high frequencies but your device may not be able to produce them or your device audio output source (speaker) may not be capable of producing such high frequencies. Since human hearing typically goes as high as in the 20,000 Hz range, good speakers can go this high but typically not much higher since people would not be able to hear it. You may want to check the frequency response of your device and speaker to see if they are capable of generating the frequency sound you expect otherwise your dog may not be hearing what you think is being generated.
