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.
