Comments on Ultrasonic Emitter for Android

★★★★★ Author Joyce Fisher · Nov 11, 2023

The Best! I had an annoying mouse in my house that drove me crazy. I put out traps; which were avoided, I made noises and threw things in the direction of where I heard the rustling of the mouse... nothing worked. I searched for apps that would drive away mice, and I ran across this one. I installed it and set it to the highest frequency. Within minutes, the rustling stopped, and the mouse was gone! I don't know if it left my house entirely, but it did leave the room that I was in!

1. Make dog whistle app 2. Spam as much humanly possible ads to make money on 70kb app 3. Get deleted and get 1 star

15kHz max. Ultrasonic starts from 20kHz. So the app name is a lie.

★★☆☆☆ Jason Fong · Oct 16, 2023

Its semi works. The problem is for most mouse and rats they hz frequency that works best for them is at the 30k to 55k hz. So for strange reasons that it worked for you is probably just very temporary. It probably just annoyed them for a bit and will come back soon...

After installing and opening for the first time, a notice pops up asking for a small contribution (£2.09) to use without advertising. The amount is fine, until you discover it's not for using all the features in the app. £2.09 allows you only one frequency! The app has very limited use with only one frequency. No mention of this was made prior to payment and one would naturally assume payment would cover all the app's features. This is not at all fair play! Uninstalled. £2.09 lost.

Saw absolutely no indication of any way to change the volume turn it up or down. Promptly uninstalled. When I use the up-down buttons on the side of my phone they did absolutely nothing.
