Post Planner

While a lot of scheduling apps are targeted at Twitter, Post Planner is specifically designed for scheduling on Facebook. Housed within Facebook itself, Post Planner lets you schedule posts as well as provides suggested content, such as popular posts in your area or viral images, which will boost engagement and add more variety to your Facebook page. While it doesn't have the cross functionality that some of the other apps have, Post Planner does have the added benefit of helping you come up with ideas of what to post, which can sometimes be the most difficult part.
