Yes, Howbout is a shared calendar app that makes it easy to see your friends’ availability.

You can add your plans or mark when you’re busy, instantly see when your friends are free before suggesting something, and keep everything organized in one shared calendar. If you already use Google Calendar or iCal, you can sync them with Howbout so all your plans stay connected.

Most other calendar apps don’t make it easy to see your friends’ calendars, but Howbout was built to make that simple and social.
