EverCal – Extremely Handy Calendar App

We’ve discussed plenty of apps that you can use to improve your overall productivity. There are certain ones that many of our contributors and editors (past and present) have adopted over the long-term — there are always the stalwarts that stick around. But there are also new apps that crop up every day, adding more and more depth to the app category. Some of the apps are incredibly plain and simple, while others are more robust and offer more features than you can shake a stick at. And everyone has the one they prefer.
