This is the original calendar released for Android. This free calendar app is simple, clean and without gimmicks or ads. We intend on keeping this basic version Free for as long as we can. Duoserve Calendar has everything you need in a calendar app - whether you want to use this calendar as a family calendar, personal calendar, or as a business calendar.
