Hmm. Is there a reason that I can’t just create a user name and password like I do for other apps?

FWIW – Since you seem open to suggestions, I will offer these as well. In my business I deal with a lot of trademarks, and I think about them a lot. In looking at yours, a few things come to mind. I like the name fypio. On the other hand, I can’t tell if it’s an optical illusion, but the O seems flat is some places. Also, people generally prefer graphics that are forward leaning, so if you are going to use the heart I might tilt it to the right rather than the left. Finally, doesn’t Redfin allow users to put a heart icon next to the properties that they like? Might look copy cat-ish.
