Your iPhone is a powerhouse do-it-all office in your pocket right out of the box, but it can do so much more with the right apps. In fact, when you find the right apps, your iPhone feels down right hobbled if they aren't installed. That's exactly how I if these five apps aren't on my iPhone.
1Password If you spend much time online, you'll have at least a handfull of passwords and login names you need to keep track of for the sites you visit. 1Password from AgileBits manages all of those logins for you, makes it easy to use unique and hard to crack passwords for the sites you visit, and when you're in the app it can auto-fill site logins for you, too. It also holds other information you want to keeps secure such as bank account and credit card numbers, plus it can use your Dropbox or iCloud account to sync with 1Password on your Mac so you always have quick access to your passwords no matter which device you're using. 1Password is priced at US$17.99 and also supports the iPad.

OmniFocus Apple's Reminders is a nice little to-do list app, but if you're looking for a serious task manager and organizer, it's The Omni Group's OmniFocus. It handles to-do lists without breaking a sweat, supports categories for organizing your projects, can give location-based reminders, shows a quick overview of your daily appointments, and syncs with OmniFocus on other iOS devices as well as your Mac. It's priced at US$19.99 for the iPhone, and $39.99 for the iPad.

TextExpander touch Even though the iPhone's on-screen keyboard is handy, it isn't always the most efficient way to type information. To that end, Smile Software brought its popular Textexpander from the Mac to the iPhone as TextExpander touch. Just like on the Mac, you can type abbreviations that expand into full words or phrases, saving you lots of time and effort when you have stuff you need to type more than once. The Smile team made it easy for other developers to include TextExpander touch support in their apps, and you can sync your snippet library between your Mac and iPhone or iPad, too. TextExpander touch costs $4.99

GoodReader If you use any cloud storage service, like Dropbox or Google Drive, you probably want to get at some of your files when you aren't sitting in front of your computer, and that's where GoodReader has you covered. It can access a surprisingly long list of online storage services, lets you upload and download files from your iPhone, and even includes built-in support for viewing many file formats. As if that isn't enough, GoodReader is a handy PDF reader and annotation app, which was actually the app's original purpose. You can pick up GoodReader for $4.99.

Fantastical Apple's Calendar app is fine, but it isn't as powerful as it could be. Fantastical picks up the slack by letting us use natural language to create events, such as "lunch with Bryan Tuesday" to set up a noon lunch meeting with Bryan for next Tuesday. The events Fantastical creates appear in Calendar, and it sports a handy list view for your appointments that's so much easier than flipping through days or weeks of appointments in Calendar. Fantastical costs $4.99.
