Do you use a social media scheduler?

Whether or not you are a social media manager, do you use a social media scheduler to assist you schedule your content? I use some, like Hootsuite and Buffer. I just discovered Metricool and have yet to give it a try. They said that you may try it for free. Except for LinkedIn, you can create up to 50 pieces of content each month.
