The first day I was able to log in, but then unable to after that. It seems like a good concept, and visually it's nice, but after I couldn't log in. Would ask me to re-authorize the connection to my Gmail accounts, I did, and still it would redirect me back to the screen asking me to connect my accounts.

I had to refund. Seems to have promise, but in my experience and reading the other reviews, it seems to be buggy.
