Using Birch Finance

Is anyone else using this website/app? I've been using it for a week or two and it's pretty cool. You are able to link all your banking info into one place and you can see how much you are spending and see if you are using the correct rewards credit card. However, I'm having a few problems with the site. Right now, Chase Freedom has 5% cash back on purchases at Wal-Mart, but it is saying I can get more cash back if I use another credit card. If you use the site, did you encounter similar problems? Being able to see your spending habits and adjust them if needed is a really cool tool.
