UNUM is a free planning tool that allows users to pre-arrange their feed 18 images in advance. You can refine image edits in the app to achieve a cohesive feed and see what your posts will look like in the Instagram grid.
UNUM also provides a "Best Times" feature, highlighting the best times to post based on average likes and comments of your followers.
