Whether you're back at the office or still working from home, organizing family vacations or helping out a friend with a project, there's a good chance you'd benefit from using a productivity app. Heck, you're likely already using one. (We all use email apps, after all.) But there are different types of productivity apps. Also, it's not guaranteed that the default app on your smartphone, which you've been using all along, is the best one for you. From calendar apps to to-do-list apps, project management apps to note-taking apps, we’ve rounded up our favorite productivity apps for your home and workplace.

A great home office is made up of more than just stuff. Sign up here for our exclusive 6-step course on how to turn your home office into a temple for productivity.

The Best Note-Taking Apps

Note-taking apps can be used to do everything from keeping a grocery list or jotting down random thoughts, to doing something as robust as preparing an entire presentation. And since we have our smartphones on us wherever we go anyway, note-taking apps are just convenient. There are a lot of different note-taking apps out there, but they're far from all the same.

The Best Email Apps (That Aren't Gmail)

Gmail is the largest email service in the world. That said, it’s not necessarily best to use the Gmail app to access your email. Nor is it always best to use the email apps that come stock with your smartphone’s software, like Apple Mail. There are superior email apps available that can better align with your needs, whether you’re a Gmail user or not.

The Best To-Do List Apps

A to-do list app can help you plan out your day by reminding you to knock out one task or chore at a time — no more procrastinating or forgetting to do something. There are many different to-do list apps out there, so it's important to find one that works for you.

The Best Calendar Apps

A calendar app is a vital tool for staying organized, productive and on schedule. But you shouldn't just pick the default calendar app that comes on your smartphone (although, it's likely a good choice) — you need to pick the calendar app that works best for you, which means the devices and software (including other productivity apps) that you use everyday.

The Best Habit-Tracking Apps

A habit-tracking app is designed to help you develop good habits and achieve your goals, which can range from exercising regularly to keeping in touch with family members. It can help break bad habits such as eating fast food or smoking, as well. There's a wide variety of habit-tracking apps out there, some with minimalist designs and some that highly customizable. Pick the one that works best for you.

The Best Project Management Apps

Whether you're a small business or a group of friends working on a weekend project, a project management app is a great tool to help everybody stay connected and on the same page. There are a lot of different apps out there and they all do different things well, from sharing photos and files to creating projects and assigning tasks.

The Best Scanner Apps

Thanks to smartphones, it's easier than ever to digitize you various documents — such as bills, receipts, newspaper articles and even photos — so that you can access them whenever you want. All you have to do is open an app, point your camera at it and — snap — it's saved in the cloud. Most scanner apps have built-in technologies that automatically cut, crop and (sometimes) color your scanned document so that it looks best.
