The most helpful feature is that I no longer have to log in every time, it's automated! This takes away some of my personal stress because now all photos are posted when they should be with one click from me instead taking several minutes logging into IG each day (or more).
There isn't anything really bad about this app if you're looking for an easy solution - especially since your friends will probably love how much easier their lives become too :) Just make sure any third party apps aren't causing issues or slowing down performance otherwise there won't be many downsides at first glance- however overuse can cause problems so test out things before getting frustrated ;) Overall happy customer here!! They've helped keep up our social media presence without having to constantly check/manage accounts ourselves which has saved us loads of work during busy periods as well as giving us.
