Marky

Marky is easy to use and figure out. It's not perfect, but 100% better than all of the competitors I have tried. Support was very quick for me.
Overall, zero problems with scheduling and posting to all of my networks, which is a huge time saver for me. I prefer to post videos which I create externally, so I can't really speak to the designer, but the scheduling feature is very easy to figure out and it WORKS (where many others have failed).

It also seems that the team genuinely wants to improve the service, so I am looking forward to what's coming next. For me, Marky is a total no-brainer. I wish I had this years ago.
