LOVE APP but NOT THE CRASHING

I have used the original free app for quite some time and just upgraded to paid version. Every time I try to open new one it crashes. Im on a new 7 Iphone. Could that be the issue? Do you have any updated version releases planned soon? Overall, LOVE the app and have always recommended to all my doggie loving Peeps!!
