Turnboards was built to manage multiple concurrent projects to help you be more productive. It is centered around making it easy to write down work items. More features are available if you need them, but they shouldn't get in the way.
I've heard so many nightmare experiences with Monday.com, Asana, and ClickUp just to name a few. After trying some of these apps, I decided they were too much work. I run several different projects that are really cool, and I just needed something besides the Apple Notepad to write down my work items.
I wanted a Todo app that just worked, worked for my projects - and worked anywhere, like writing on a notepad with a pencil (No cell service required).
