The application stands no where to its description. Pathetic functionality with clueless user interface.. I never hated any app as much as I did this one. Please have mercy on this world and never ever develop these kind of apps.

My dogs didn't even hear the dog repellent pulse. So false advertising. All the good tones require u to pay

Starting just now no mosquito showing in room let's see what happens later :)

Very hard on the ears after listening to a few of the frequencies, but it works, high pitched and annoying ;-)

Just download and tested, some of the feature works and those sounds are very low...one star to think for such design.

I did this when my friend was walking his dog and it looked at me it was kind of funny

Only a few frequencies work, and on and on the bench, it was proved that none of the phones tested, their speakers can not reproduce the high end frequencies. It just spams you with ads, just junk to make money from ads!!!!
