Finally, a simple and clean app!

This app is exactly what I needed. It doesn’t require another calendar to work, and will simply let me color coordinate days. I can choose which days have which colors, and these colors signify something to me. It seems to be marketed perhaps for menstrual cycles but that’s not even when I’m using it for. Sometimes all those extra bells and whistles are just annoying, I love this app!

Feature request: perhaps a small notes section? I’m using this for a diet and it would be nice to occasionally scribble down my weight.

Great. Suggestion

Great app. It was something I was looking for exactly. I’m glad it doesn’t make you sign in or make an account. Super simple.

I would like to see a “reports” option allowing you to select a date range and then generating a report showing how many days of the total you have marked.

It did exactly what I wanted it to do! It marks days with different colors depending on the calendar you choose! It is super elegant and fast! Just the app I wanted!
