Thank you so much for sharing this!
I've been looking for a calendar to keep track of my errands as well as my business duties. It does cost some money, but I believe it is worth it.
I believe that having a minimalist calendar is an exceptional way of keeping yourself together, especially since it does not have distracting designs nor words.
Personally, I love how this app also tracks the hours I spend on a specific task, this helps me minimize the time I spend doing irrelevant things to focus on the ones that indeed matter.
