How difficult is it create a schedule post Page app? Is there any free to download? What kind of hosting do i need to host it?
It so easy. You can use rss and integrate with facebook API. About free download I don´t know. Try fiverr.com to find someone who make it for you. I have some simple fb app on a free hosting.
you mean do a wordpress blog and RSS the content? But if i do not want a RSS just post images from a database? What hosting is that?
Check out the scripts forum in the marketplace, i've seen quite a quite a few Facebook post scheduling scripts pop up...
