Dear developer, Could you add total number for each event calendar please? Thanks. ### 4/5 — Very well *2019-02-03* It’s simple app, very comfort and nice, but why I can’t use more than 5 markers at the same time? ### 5/5 — BEST Habit Tracker *2018-12-22, version 12.1* Most simple and versatile tracker out there. ### 5/5 — Great. Suggestion *2018-05-22* 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. ### 5/5 — Finally, a simple and clean app! *2018-01-20* 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. ### 5/5 — Just what I needed *2017-12-15, version 11* Love this ### 5/5 — Nice app *2017-07-30, version 11* Good app. One minor issue, the icon name is called Periods though the app name is Cal Marker. I prefer the latter. Thanks ### 5/5 — Amazing *2017-03-01* 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! ### 5/5 — Awesome! *2016-08-09* Im waking up at 7am everyday for the next 30 days and this is so easy to track that. Amazingly simple product! ## Frequently asked questions about Cal Marker ### What is Cal Marker used for? Cal Marker is a utility app designed to help you mark specific days on your calendar.
