I figure I need a doe Bleat to make the call more realistic. so I found this app and figured what the heck, I’m not seeing anything without it so it can’t be worse. anyway, I used the doe Bleat, and followed with 2 soft grunts. about 30 seconds later this buck comes full speed right for the tripod. I got a shot and downed it. I had been grunting all morning and this app got me my buck!" -A. PlumleyPlease note, that some phones and tablets can not reproduce these high quality sounds correctly. If you are not satisfied with the quality of the sounds, then I would recommend getting a an external battery powered speaker.Amazon has a great portable battery powered speaker that I use, and recommend.
