CalenGoo integrates with Google Calendar and displays events in the same colors you’ve chosen on Google Calendar. Plus, it recognizes visible and hidden calendars.
Compatible with iOS and Android, the app lets you make changes to your calendar, even when you’re not connected to the Internet, and then syncs when you are.
The app also allows you to invite people to events, and integrates with Google Tasks for creating task lists.
Price: from $5.99
Organizer for iPhone is designed to work much like a traditional organizer. A blank canvas of sorts, you can include virtually anything you could write on a piece of paper.
The app lets you customize events in your calendar with text, diagrams, emoji (it includes 182), pictures and maps. Record voice memos and play them within the app.
Pocket Informant is a calendar and task management app for Android. The app’s pre-made filters help you quickly find different tasks, and its built-in templates help to create different types of events and tasks. Its configurable interface — with over 100 different options — customize the app to meet your needs.
Counting down the days to a big trip or your retirement? Countdown Calendar lets you know how long until the big day, complete with hyperlinks and notes for each event.
The app supports multiple events (so you can count down everything in your life), and has a central repository of countdowns for universal events, such as movie releases and sporting events. Just download them to your own calendar.
Week Calendar gives you a quick overview of all your appointments for the week. Color-code individual events, link contacts to specific events, and share events with others via email.
Touch Calendar takes a different approach than some other apps out there — the entire calendar is viewable from a zoomable, scrollable interface, rather than several different calendar views. For instance, if you’re looking at a month view, you would simply zoom in to see by week.
The full version of the app also includes a widget to view your calendar from your phone’s home screen.
Need a gentle, audible reminder about events on your calendar? Calendar Alarm shows your appointments in a clear list, day, week and month view and lets you add notification sounds to existing alerts — the app has 25 built in. With iOS 5 and above, you can also use music or ringtones as alerts.
