Really needs improvements

It seems like this app is getting worse with every update. It saddens me that iPeriod doesnt keep up with iOS upgrades and hasnt really revamped their app for what seems like forever. This app is basically now useless to me with iOS 9.1 on my iPhone 6S as the app notifications dont pop up, the entire layout is off, and it keeps crashing. PLEASE just spend an extra dollar or two to update this app to 2015/16! If not for me, do it for my suit pants that I keep bleeding through!
