I'm sad and disappointed that this app is going away. It's discouraging that Intuit hasn't considered keeping Mint as a paid service. Nay, I'm surprised it wasn't the first option for Intuit, considering it could stream steady revenue from many users who would happily pay to continue years of satisfied usage.
I am also looking for an acceptable substitute. I haven't tried any of the options mentioned in this thread, but I did find this comparison article:
