Did not work at all
With thousands of Seagulls on my buildings roof, I connected to a Bang and Olufson speaker for maximum sound reproduction quality. Blasted it at the seagulls. They just looked on, amused. No effect whatsoever.
Response from developer
Seagulls learn very fast and soon they can tell if the sound is generated from a speaker or a real predator. According to my test, the sound works well in a wild environment but doesn't even work in a noisy city street. I am sorry if this app does not work for you, please initiate a refund. On the other hand, the sounds for crows and ravens work well in almost all types of environments. I believe this is because these soundtracks are speaking in crows/ravens' own language, so these birds can understand and react accordingly. This is also the reason why we have to distinguish crows from ravens in the first place, then play the correct soundtrack to scare them away.
