$1.99 (on sale) Time tracking
Tracking your time as a freelancer can be difficult with stacks of time sheets and paperwork to manage. [[xref:http://www.pcworld.com/appguide/app.html?id=65205|ClockIn|ClockIn]] is a simple and efficient program that allows you to monitor the time you spend on a project and among multiple clients.
With a few taps, you can punch in and out, and have the app track your shifts (and even if you close the app, it remembers whether you punched in or out). At-a-glance information about the current shift remains at the top of the screen for your convenience, and you can filter reports based on a client’s name.
The app can manage multiple clients, and it stores their names, Web sites, and e-mail addresses. To export your hours spent on project data, ClockIn uses HTML or CSV (Microsoft Excel compatible) format and attaches the information to an e-mail message that you can easily send to your computer.
