If you’re looking for a tailor-made student planner, you need look no further than Due Yesterday. Unlike some organisers marketed at students, Due Yesterday was designed for school use, and so it isn’t full of extraneous or unneeded features. That said, it does include all the features you’d expect from a planner of its type, including a nifty GPA calculator.
The program is easy to use, simple enough that it’s not going to take up all your assignment time, and small enough that you shouldn’t need to uninstall any of your other programs to make space for it.
As well as being regularly updated with new features, Due Yesterday is completely free! If you’re a student on your way to college, or you know one, this program is highly recommended.
