Inertron Software's InerTrak is designed for freelancers and others who work solo and who need to track their clients, the number of hours they devote to a project and calculate how much they're owed based on their hourly rates.
InerTrak's interface is not particularly fancy, but it does the job.
InerTrak is easy enough to figure out, but if you need help, there's a comprehensive help section that will take you through it step-by-step.
Start by tapping the Clients icon on the bottom menu bar and on the Clients screen, tap the plus sign in the upper right corner and enter the client's name in the space provided. Add your hourly rate if needed.
Next tap the Projects icon, tap the plus sign again, go to the Projects screen and enter the project name and select the name of the client you entered into the Clients screen.
If you entered an hourly rate in the Client screen, it should automatically appear on the project page of InerTrak. That's the idea anyway. I found that I had to re-enter the hourly rate into the project screen for some clients.
To start the timer on a project, go to the Project page, tap the stopwatch icon next to the project and client names and the timer starts. When you complete the job, tap the icon again. From there, you'll go to the Project Details page where you'll see the names of the project and clients, hourly rate, date and amount generated over the time of the project.
You have the option to quickly synchronize your data with your desktop. However, you must have the InerTrak desktop client, which costs $45, and be on the same wireless network.
Alternatively, InerTrak features an export capability so you can email data in CSV format to yourself and copy and paste it into Microsoft Excel or a similar spreadsheet app.
When I experimented with InerTrak's various Settings, the app crashed, but that appears to have been a one-time thing because I could not repeat it.
Bottom line, InteTrak on the iPhone is a good app for a self-employed person with simple needs at home or who works on site. You'll get the most out of it if you use Inertron Software's desktop client, which gives you additional options for project management and billing.
