Will not open – Dreamboard, the safe and secure self-tracking dream journal Review

I used to use this app, got out of the habit but it stayed on my phone. Now I want to use again and it won’t even open at all. I see MANY other have had the same problem for a long time. Has the developer abandoned this app?
