20 Best Calendar Apps for iPhone + Videos

Your iPhone already comes with a standard calendar. But there are many third-party applications available that make tracking your tasks and events much easier. Choosing the right calendar application for your needs does take some researching as not all apps in this category offer the same features.

How to choose the right iPhone calendar app:

The App Store has many third-party clients you can take advantage of to keep yourself on schedule. Not all of them have an easy-to-use user-interface. Many of them are too complex to use and do not have the right features. Here are a few factors you may want to pay attention to when choosing your next iPhone calendar app:

• app speed and stability
• user experience and design
  
• customizable features and advanced options
  
• responsive search
• sync features (e.g. Outlook, Facebook, Cloud, …)
• support for voice-commands and natural language
  
• alarms & reminders
• developer track record and reputation
• geo-location & social features
• universality (iPhone, iPad, Mac, Android, and Windows 8)
• price & regular updates
