In an inter-connected world keeping track of your time can be a challenge.

While smartphones and tablets offer a galaxy of time-sucking options such as Angry Birds and Words with Friends, there are an equal number of apps that will help will help you make better use of your time in no time.

Here are five of our favourites.

Things

Things is a popular, elegant and easy-to-use task-management app that is based around organising and completing to-do lists and projects. Recently updated with cloud-synching, Things now allows you to update lists from smartphone, desktop or tablet.

At $10 Things is not the cheapest app on the market, but its usability and depth make it excellent value.

OmniFocus

OmniFocus is an award-winning app that exists to help you streamline every aspect of your personal and business life.

OmniFocus lets you enter notes via voice and images, however the standout feature is its location-awareness function. Using your smartphone's GPS, OmniFocus can suggest the most efficient actions based on your location. For example, if you're near the office why not pick up that package? Are you passing the supermarket? OmniFocus reminds you you're out of milk.

Not nearly as nagging as it sounds.

Cruxbot

Ever wanted to look for a keyword or topic but don't have time to scan everything in your RSS feed? Cruxbot's here to help.

This clever app scans articles and websites for keywords and summarises them – meaning you can find what you're looking for faster.

CamScanner

CamScanner turns your phone into a scanner, allowing you to take photos of receipts, bills, documents and so on.

This free app allows you to crop images, create PDFs and synch to other programs including Google Docs, Evernote and DropBox. Goodbye fax and printer.

Cue

Clever Cue takes all your appointments, including those from Facebook, and puts them into one easy-to-access list.

Better still, Cue then attaches relevant information such as phone numbers and emails into that list, meaning if you're running late no more scanning through hundreds of emails to find an address.

As an added bonus, Cue also features weather forecasts and reminders.
