EasyTasker Keeps it Simple

Australian firm EasyTasker has launched its iPhone web application of the same name for small to medium-sized businesses looking to manage their business activity, staff and projects. All activity is synchronised between all devices, which means the information relating to each project only needs to be entered once.  
The app includes modules for projects, timesheets, invoices, expenses, To Do lists and internal messages. It comes in four versions: Freelance, Small Business, Medium Business and Big Business. Prices range from Aus$20 (11) per month for the freelance version, to Aus$100 per month for the Big Business version.
