A close friend needed an app to mark dates on a calendar and easily share them with her doctor. To my surprise, I couldn’t find a simple, convenient app for this in the App Store. That’s how Cal Marker was born: an app that lets you mark dates on different calendars and see all your marks together.
If you’re keeping track of something regularly, the app can remind you to add a mark for today.
A review
from App Store “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!”
