Yes, Howbout is a shared calendar app that makes it easy to see when your friends are free.

You can add your plans or mark when you’re busy, and instantly see everyone’s availability before suggesting something. It keeps everything in one shared calendar so you don’t have to ask “when are you free?” every time. With color-coded shared calendars, it’s easy to spot days that work for the whole group instead of back-and-forth messages. Howbout is also free and available on IOS and Android.
