Feedback for miles/credit card points optimizer

Right now our app Card Curator is focusing on optimizing credit card miles and points for travel (and all other rewards). What are some things that people would like to see or get out of an app like this? Do people prefer to let things like this run on their own, or is an educational aspect important as well? Also, what are some recommendations to get people interested in using miles for travel and optimizing cash back? I know it seems like a no brainer, but getting people to do new things can be tough! Thanks for the feedback and check us out on Product Hunt if you're interested in learning more.
