I get ads in a free app, but ads with sound in a tone generator makes it seem like I'd be better off sitting through a time share presentation than trying to use the free version. I'd have considered the full version but full screen ads for brain rot games, blasting at full volume - because this is a sound app - every time I turn the whistle on or off, makes this one a hard pass.

Perhaps one of the best dog whistle apps. It's easy to use, quick to respond to frequency changes, and most importantly, the ads are unobtrusive and don't interrupt the functionality of the device. The Only negative that I can think of instead it doesn't respond 100% instantly to the frequency changes, but that would also require more CPU power to achieve, so kudos on that! 9.5 out of 10 my friend! = )
