Over the years here at Lifehack, 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.

It’s been our job (and still is our job) to keep abreast of all of the productivity-type apps out there. As a result — and as a bit of a refresher — we’ve put together a list of 40 best productivity apps for iPhone (all categorized based on their functions) to provide you with an all-in-one resource for you.

For Getting Things Done

1. OmniFocus
