Expensify (Free)

Skype (Free)

Make video calls to Android tablets, phones and computers using your smartphone with Microsoft’s Skype app. Its video calling capabilities (as well as text chat and group calling features) make it great for conducting meetings when you’re away from the office or for checking in with your team when you can’t be there in person. Best of all, it’s free to call devices and computers that have the Skype app.

Locale ($9.99)

Locale lets you program your Android device to do certain things based on “geofencing” technology — basically, you can set your phone to take certain actions when you reach certain places, like the office. The main use is to have the app automatically switch your phone to vibrate when you hit the office, so you can avoid having calls go off at inopportune times, like during meetings. You can also program lots of other different automatic functions based on where you are.

Google Drive (Free)

Google’s cloud storage service is handy for a lot of reasons, but its best features are for getting work done remotely.

You can also collaborate with other users on documents in real time, as if you never left the office at all.

GoToMeeting (Free)

A more dedicated meeting app, GoToMeeting makes it easy to tune into video and audio meetings using your device’s Internet connection. You can use GoToMeeting to quickly tap into conference calls, and the app also displays presentations and any other data that’s being shared over the Internet using the GoToMeeting service. It’s basically like being in the room — or at least at your computer for a virtual meeting.

LinkedIn (Free)

Social network LinkedIn is geared specifically at professionals and business people, and it’s a great way to get in touch with your old contacts or to create new ones.

AllCast (Free)

Evernote (Free)

Your Android device turns into a scratchpad and to-do list with note-taking app Evernote. You can use the app to jot down quick bits of information in text form, or record audio and voice notes for yourself if need be. You can also sync all your notes to the cloud, making them accessible from whatever device you need to access them, and Evernote provides a search function to help you find specific info or keep from losing important notes.
