I got the app expecting to get truck sounds. That didn’t happen:( The only thing they have is pictures of trucks. When you touch the pics, no sound comes out. The reason this app has so many 5 star reviews is because they make you give a 5 star review to unlock more sounds. I thought this would make the app actually work, but that was not the case. Overall, a total scam, don’t bother getting this unless you enjoy looking at silent pictures of trucks.
