For part of AH social media planning, various apps like this were researched. We're still undecided on which one, but my personal favorites were Hootsuite and BufferApp. Buffer is a lot simpler than HS but it's also fairly limited - it depends on what you are looking for in the app.. Maybe give Buffer a go, see if it's for you (it's definitely not for everyone). Let me know if you've selected a different one
I like Hootsuite but I've had a few problems, it's posted hours before scheduled, and I don't like that when it works, and I say post at midnight, it post at 11:59, and I can't say 12:01 to account for that minute, I have to do it in five minute intervals. This makes holiday messages more of a challenge.
