App not working – Inkpad Notepad - Notes - To do Review

I’ve been using this app since it’s been available and I’m sad that I can’t use it on my iPhone any longer. I’ve tried removing and re-downloading it several times. My screen is gray and I can’t see any of my notes saved. It’s been so inconveniencing not having access to anything.
