The iPhone has definitely evolved into something that people can’t live without. Quite surprising for those who initially laughed when it was first introduced, knowing that at that time, phones looked completely different and performed entirely different tasks.

Especially when it comes to business, a lot of business owners have realized how truly important their iPhones have become. A lot of iOS apps have proven to be quite efficient for important business processes and have made the lives of businesspeople easier and less stressful.

If you’re still looking for apps that could help you and your business, here are 5 apps that experts who sell iPhones highly recommend:

• Microsoft Office

It’s already one of the most useful set of programs in your laptop – who’s going to stop it from being a must-have in your iPhone, too? Now that you don’t even need an Office 365 account to make it work, MS Office has definitely become a more sought-after app than Apple’s very own iWork. It is broken down into separate apps, allowing you to pick which ones you need the most – Word, Excel, PowerPoint, etc.

• Adobe Reader

As a businessperson, you probably go through a ton of documents day after day, a lot of them in PDF format. This is exactly why you need the Adobe Reader. It allows you to read PDF files and add comments to them even when you’re on the road. Sure, Apple already has a built-in PDF reader in some of their apps, like Mail. But if you have to sort through so many in a single day, getting the standalone app would be better.

• Genius Scan

What if you’re the one who needs to send a PDF? Because you can’t create PDF files directly from an image you have, Genius Scan jumps in to fill in Apple’s lapse. The app allows you to create PDF documents directly from images. It even helps you find the best lighting and camera position to make the PDF file as clear as possible. It also lets you send the resulting document to your Dropbox, Evernote, Google Drive, and other apps you use.

• Gmail

No businessman can live without checking his emails, so you would definitely need your trusty Gmail app with you everywhere you go. Gmail basically allows you to do almost everything the web-based version does. It can even be integrated with other Google apps you have, like Google Docs.

• MailChimp

Just because you’re away from your computer does not mean that you won’t be able to send your newsletters on time. MailChimp has a mobile app that allows you to stay within your deadlines and distribute your email newsletters to all your subscribers. You can even keep track of your analytics while you’re at it, allowing you to see how many people have opened your email, where they opened it, and so on.

Without a doubt, the iPhone has become such an important business tool, especially for business owners on the go. Add these business apps to your iPhone, and you take your phone’s usefulness to an even higher level.
