As a student, Stacks is now the main help for my productivity. It definitely helped with managing my assignments and projects in school. I could also see myself using it for my creative projects in the future. From day one the devs have also been very helpful and responsive. As this app is still in constant development, they take into account requests and have been releasing great updates. I look forward to the growth of this app.

I have tried all sorts of project management tools and none come close to Stacks. The thing I love about it is the simplicity. I am able to categorize my projects and boards in a way that makes sense to me, so that I can always get a clear picture of what needs to be done and when. There are also other helpful features like the traffic light information
