Crashes

I have an iPod touch 4 64gb. This app worked perfectly up until about 7 mo ago. Every time I try to launch the app it crashes. No issues with Internet connections or my other apps. I tried deleting it then re-install and it still doesnt work. Yes my operating system is updated. Any suggestions? Ill check back in about a week but after that Im going to finally delete app if still no fix. Its been taking up space on my Itouch long enough! I really liked this app:(
