Top free, essential business apps for Apple's iPhone

Whether you're running an SMB or need to keep track of your expenses to cash in later, you no longer need to rely on pen-and-paper records. Apps such as Check and Expensify give you overviews of your accounts, cash flows, expenses and investments. Check is a clear and concise app which is useful for budget planning, whereas Expensify also includes the option to monitor your credit score. 

If you want a more comprehensive solution which includes budgets, reporting tools, synchronisation across accounts and PIN protection, consider using Mint.

However, document storage facilities may not help when you need to annotate and share specific document types. PDFs, for example, are often used for contracts and reports, and if you need to check and sign these files quickly, a dedicated viewer is a necessity. A range of free apps are available on the market: SignEasy allows you to sign and fill in documents on the go; PDF Reader is a user-friendly app for annotating and altering .PDF files, and PDF Splicer is a handy app for slicing and dicing hefty .PDF files into multiple parts. 

Third-party apps aside, don't forget to explore iWork -- Apple's native solution for viewing and editing documents, spreadsheets and presentations.

In addition, as controversial as the app may be, Uber's personal taxi service can get you out of a tight spot if you need a ride. 

Hipmunk is an interesting alternative travel planner as the app includes alternative accommodation such as Airbnb and Homeaway, as well as flight and standard hotel searches.
