Emergency Calendar (eCal)

By Trek Medics International, Inc

This app is only available on the App Store for iOS devices.


Emergency Calendar (eCal) lets you create and display any shift calendar used by fire departments and emergency medical services (EMS). eCal was designed for low-tech, easy use to allow users to personally customize their shift schedule -- whether it's a 2/4, 4/6, 48/96, or any other Platoon/Kelly combination. Video Tutorial:

*** IMPORTANT (Please Read) ***

The Emergency Calendar creates' any Kelly/Platoon schedule by using the repeating pattern unique to that specific schedule. For that reason, it is important that the User only includes one complete Rotation/Cycle when creating their calendar.

2/4 Kelly = 12-day Rotation/Cycle/Tour
3/4 Kelly = 9-day Rotation/Cycle/Tour
4/6 Kelly = 24-day Rotation/Cycle/Tour
48/96 Platoon = 6-day Rotation/Cycle/Tour

Please DO NOT attempt to schedule by week, month or single "go-around", as these do not reflect the pattern that determines each schedule.

Easiest to visit the website:


To get to the EDIT CALENDARS view, press the third button at the bottom of the screen. The pre-existing calendars will show up in a list.


You can delete calendars, change their position by dragging them, or select them to edit. You can add a new calendar to the list by clicking the ADD CALENDAR button to the bottom right.


To create a custom calendar, first enter the calendar NAME in the top text field. To customize the schedule, select the START button and then click the start date of the first day of a given cycle. (For example, 2/4 Kelly = 12 total days; 4/6 Kelly = 24 total days; 48/96 Platoon = 6 total days.) Then select the END button and click on the last date of a single, completed cycle. Once you have selected the Start and End Dates, the Start date will be highlighted in green, the End date will be highlighted in red, and the dates in between will be highlighted in yellow. To configure the appropriate colors for their respective shifts, select a color at the button of the screen and then click on the corresponding dates in the pattern. Once the colors are filled in, SAVE the calendar. When you return to the original calendar list, you will see it has been added to the list of other calendars. To view the new calendar, click the VIEW CALENDARS button at the bottom left of the window. The schedule you made will be repeated throughout the calendar.

This application uses a modified version of kCalendar, which is open source and free to use. To use kCalendar in your projects, download it from

Customer Reviews

Glad to see it back in action!

After a loooong absence, and apparently under new ownership, very glad to see this updated and working again. Still want to see it worked in with Apple calendar, but for what’s advertised, definitely worth it.

No bullsh*t- best Kelly app. Just use this one and be done with it

Not a reviewer but feel the need- this is the best Kelly app- I’ve tried all of them- don’t waste your time on the other ones that charge you MORE MONEY after you set them up and blast you with bullsh*t emails trying to sell you more sh*t all the time (they all do). Super simple and easy to use. My whole dept. uses this one now because it actually works and you won’t have to drop extra money into it just to manage your schedule. Simple, perfect and idiot-proof and won’t rip you off. Save yourself the hassle and just use this one.
