No bird calls

Do not purchase if you want bird calls as the bird call feature did not work at all on my iPhone 3gs. Reinstalling and rebooting did not help either. I emailed the developers twice asking for assistance and they still have not responded more than a week later. Apple immediately assisted me and hv refunded me so a big thank you to Apple but a big vote of NO to this app and to its developers.
