Cant open app after upgrade

Running iOS7 on an iphone 4S, and since the update, the app wont even open anymore. I guess Ill be off Growlr at least until the next update. Perhaps of more interest to Growlr, I wont be seeing their advertisers ads until they fix that very major problem. This is the third time among recent updates that this problem has happened. I wish the programming staff at Growlr could get their act together
