Week Calendar may be another iOS hand-me-down, but it's a good one - an intuitive interface and comprehensive feature set have made it one of most popular calendar apps to hit Apple's App Store. Android has no shortage of calendar options available, but few are this simple to use.
People who despise the amount of effort necessary to stay organized should take notice. Week Calendar doesn't weigh anyone down with a complicated setup process. It simply imports from Exchange, Google, Outlook, Facebook, or other calendars that are already configured on your device. Managing the app is even more straightforward. Events can be rescheduled using simple drag-and-drop, and appointments can be duplicated by just copying and pasting.
