Please update to iOS 11!!! – Menstrual Calendar Review

I’ve been using and LOVING this app for 4years now and now I can’t access it because the developer stopped updating the app! Please at least figure out a way for us loyal users to retrieve our important documented cycle information. I have a very tricky cycle and it helped so much to be able to go back to info from years ago to compare to! Update to iOS 11!!!
