We use Trello for marketing activity planning, Planyway fits perfectly to our needs to get a shareable calendar view for the whole company.
I manage multiple clients' social media accounts and Planyway has made planning each social media calendar so easy! I love being able to look at the calendar view and drag and drop ideas from my Trello boards to schedule different posts.
Using Planyway for my social media calendar makes my job much easier. I can see what's coming up and then label the Trello card when it's done. Love it.
