Calendar Counter

The Calendar Counter app is a quick and easy way to make a follow-up or future appointment on your iPhone calendar by adding years, months, weeks or days to the current date.



I often wished for an easy to use app that would assist me when I needed to make a follow-up appointment after a set period. I first needed to open my phones calendar and to then to physically count the number of weeks or days to get the exact date.
When my friends, and myself could not find an app that did what we needed I created the Calendar Counter app.
With Calendar Counter it takes seconds to add years, months, weeks or days to the current date to find the exact follow-up date for the calendar event.
Calendar Counter lets you preset the default period of your event and the period for the first and second alert if you wish.
When you tap the add to calendar button these presets are automatically added to your phones’ calendar event settings to save you time.
Calendar Counter is designed to be easy to use and the screens are designed to be easy to read.
The Calendar Counter app does not have in-app advertising.
The Calendar Counter app does not have in-app purchases.


The Calendar Counter app uses the local time zone of your iPhone for all calculations based on the Gregorian calendar.


The color scheme of Calendar Counter can be changed by selecting a color from the available list of themes.
