Scared away the noisiest mice...

We were staying in a cabin with some very noisy mice in the walls - chewing and scraping all night. I put my phone in the cupboard where the noise was loudest, and left this app running. The mice went crazy! They squeaked and squeaked and then ran to the other end of the house and stayed quiet all night. I don't know if it would work long term, but it definitely gave us a good night's sleep we wouldn't have got otherwise...



This app is the best at what it does. The frequency range is a big factor in deciding which app to get and this app can go al the way to 30000hz is a huge leap from similar apps. The fact that this app is built from ios8 is awesome because it has a new interface unlike the other apps which are outdated.

What the frak

Disappointing big time. This thing should be free. The tone selector is horrible because it's a slider. It jumps from 15 hz to over 200hz. So if you want to experiment with specific frequencies, you can't. Wish I wouldn't have wasted my money on this one
