Hi, I'm looking to see if there an app out there that helps you track money between you and a roommate/friend/etc, In this case it is with my roommate. Getting e-transfers and lending cash here and there makes it hard to remember which bills I got money for and which bills I didn't. I would need the app the sync between myself and my roommate (iPhone and android). We write it down in a book but when you get the money while you're out you always forget to write it down! Any suggestions?
