Ask HN: What do you think of our new iOS app? Promo codes inside

We've made a new app called Reminders with Friends that uses Gamecenter multiplayer instead of our server to send and receive time and GPS triggered reminders. I really like this community and wanted to get some feedback. We do recognize there are some UI changes we can do to streamline the app, but any feedback would be great.
