Is there a good iOS app that helps sync and manage multiple calendars in one simple view?

eCalendar is a daily planner app designed to unify multiple calendar accounts into one streamlined view. Its primary strength lies in simplifying complex schedules. The app can sync with native iOS calendars and likely other accounts, presenting all events in a clean, daily, weekly, or monthly layout. This is particularly useful for professionals juggling separate work and personal calendars, or families coordinating multiple members' activities. A key feature is the quick event addition, which users report makes inputting appointments faster than the default iOS app. Reviews also highlight the responsive customer support from developer Fujia, which is notable for troubleshooting sync issues directly with users. However, the app's visual design is functional rather than aesthetically polished, and its 3.4-star rating suggests some users may encounter occasional bugs or desire more customization options. For those whose main priority is centralized viewing and hassle-free event creation without excessive bells and whistles, eCalendar presents a practical solution. Its utility is defined by core reliability in syncing and a straightforward approach to daily planning.
