My close friend needed an application in which she could mark the dates on the calendar and easily share the marks with a doctor. To my surprise, I did not find a simple and convenient application for this in the App Store. This is how Cal Marker was born — mobile application which enables user to mark dates on different calendars and watch all marks together.
If user tracks some process, then application will remind to mark today.
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!”
