About

To Do List

Dumb Calendar is a productivity app that helps you plan your week in the most non-distracting way possible. It achieves this goal by limiting your view to one week at a time and clearly dividing each day into a limited amount of tasks. Our calendar / to-do list has all the essential features you would need: you can copy the same task for multiple weeks using 1-month or 3-month repeats, you can satisfyingly toggle tasks you've already completed, and you can fly through your list with intuitive keyboard navigation. Plus, using Review Mode, you can motivate yourself to do more by automatically highlighting days you've done nothing. Feel free to leave your reviews and suggestions. We are a small team, but we would gladly implement community-favored features into future releases.
