Cal vs WAVE calendar

As long as Facebook is already set up on the device, Cal integrates with it with a single click to show all birthdays.

The app displays agenda as a combination of events and to-do list items and uses different background images for each calendar day based on chosen themes.

Cal integrates with Any.do to-do list app for task management.

Cal uses Google Maps to show event location, Waze for real-time traffic information and Uber for hailing a car to the event.

Cal has a good-looking resizable widget that has a shortcut for event creation.

A feature called HeadsUp will show pop-up notifications on phone's homescreen specifically designed for meetings. The content of the pop-up will change based on whether it's before, during or after a meeting.

Before a meeting it will show shortcuts for getting a taxi or a car, seeing attendees, getting directions and notifying other attendees if the user is late via e-mail or Skype. During a meeting it will give shortcuts for setting the phone on vibrate, taking photos, video or audio-recording, adding tasks that will be synced with Any.do or e-mailing a summary. After the meeting it offers sharing task list and scheduling a follow-up.

While adding an event the app will offer suggestions, help invite other people, pick a location, allow making a note and set it as a recurring event if needed.

Cal allows adding events simply by speaking.

Available in English, Dutch, Spanish, Swedish, Italian, Portuguese, German, Chinese, and Russian.

If a location to an event is added, the app will show a map and allow pulling up Google Maps for directions.

Wave allows creating local and Google Tasks to-do items that can be synced across devices and color-coded.

The app has day, week, week-agenda, month, month-agenda and list views.

Day, 3-day and week views split up the days horizontally and hours vertically.

Week agenda splits the screen in 6 equal parts - 5 parts for work days, sixth for weekend. Double-tapping a day will open a list of events for that day. From here swiping left and right allows moving between days.

Month view splits the screen in half with one half displaying a typical month view with color-coded dots next to dates to show which days have events and the other a list of events for the selected day.

Month agenda view lays out all days in a grid and displays all event for the day.

The list view is actually the closest to a typical agenda view despite the name. The difference here is that there are two modes of showing that information - default and detailed. The default mode displays date, time, event name and location (if available) and the detailed mode displays extra information such as what calendar is the event part of, who's attending, notes, etc.

Another app on offer from the publisher is WAVE Scheduler, which integrates into WAVE Calendar for easy event planning.

The app will color-code different calendars in different colors as well as allow selecting a different color for each event.

The app has a store for sports, stock exchange, holiday, religion and other calendars.
