As Liz Phair sings, "It's nice to be liked, but it's better by far to get paid." And often the only way to get paid is to be able to say exactly how long you worked. For that, you need a time tracking app. Time Master
($9.99) fulfills one of our prime requirements for a time tracking application--it lets you track time either by entering start and stop times or by entering duration directly. It can manage multiple running timers and keep the timers going even if the app itself isn't running -- important in the (so far) monotasking iPad. Time is tracked according to client, but you can also further break it down by projects and tasks. Similarly, you can set billing rates according to client, project, and task, or just have one billing rate for everything. You can also use the app to track expenses and assign them to a particular client or project.
Two in-app purchases make Time Tracker even more useful. The Invoicing module lets you create and email PDF invoices right from your iPad, including your business logo. And the QuickBooks Export module will export your entries as an IIF file that can be opened in Windows QuickBook 2007 Pro or later (no Mac support).
