iOS: Fantastical is our favourite calendar app for the iPhone. Today it has received an update that adds a heap of new features, including better notifications and integration with your dialler.
The big additions here are the new notification options. You can now give Fantastical notifications a sound, and you can choose whether the badge displays remaining events, reminders, or incomplete reminders. There are also a lot of minor improvements, including the ability to add a phone number as a location that you can quickly call from, some improvements to the parser, and some bug fixes.
