The ability to have a client approval page that doesn't require specific logins for the client. Just create and share a URL and they have the ability to see all the posts, edit, comment, approve or reject. Out of the many apps I tested, eClincher had the most features for what it cost and included Google My Business integrations where many didn't. Review collected by and hosted on G2.com.
The user interface can be a little awkward at first, it's not an app that's exciting or satisfying to use compared to others that obviously invest a lot in UI. Review collected by and hosted on G2.com.
