Track Time and Create Invoices on Your iPhone With Timewerks

If you have an iPhone or iPod Touch (s aapl), you may be interested in track-tracking and invoicing app Timewerks. Timewerks is probably best-suited for those who don’t have laptops with them all the time. But for web workers wanting a more portable invoicing solution, Timewerks is still a good option.


Timewerks creates invoices and tracks billable hours and materials used on a per-project basis. You begin by creating projects. The application contains five primary screens: Projects, Invoices, Clients, Work Items and More. The features in More include Data Export, Help and Invoice Color, while the Clients section integrates with your phone’s Contacts so you don’t have to enter contact information twice.

Using the Timer

In my test, at first I thought that the timer had a bug. As you’d expect, you tap Start and Stop to manage the timer as you work on a task. After stopping the timer, you can associate the hours with a work item. The problem I had was that the work items I added when setting up my projects didn’t show up as an option right away. Eventually, the items did appear in the list of tasks — but it’s not clear what made that happen.

The Project Summary screen provides a clean overview of the project, complete with time spent, billed and unbilled items and direct access to that project’s invoices.

Create and Customize Your Invoices

You can invoice by hourly rate or by item and create items for expenses and materials. To include your company’s information on invoices, go to Settings on the iPod Touch or iPhone and look for the green Timewerks icon. The only customization option available (through Invoice Colors) is the background color of the invoice. I’d recommend leaving it as the default white, as the limited color choices don’t really improve the invoice’s look. For example, here’s a wheat-colored invoice.

When you create the invoice, you can add the tax rate, if applicable, and email it to your client. If you need to accept credit card payments, Timewerks integrates with Inner Fence’s Credit Card Terminal. The credit card application is a separate product, but at least you have a way to accept credit card payments as part of the invoicing package.

Export Your Data

Data Export gives you the ability to export Timewerks data to use in another app. You can access the exported Comma Separated Value (CSV), or a Tab Separated Value (TSV) files from any web browser connected to the same network as your phone through an address provided by Timewerks. It took me a little fiddling to get this feature to work. The app provided http://localhost.local:8000 in my test, which didn’t work. I had to use the following steps to get my local IP address:

  1. Go to Settings on your iPhone or iPod Touch.
  2. Tap Wi-Fi.
  3. Tap > next to your network, under Choose a Network.
  4. Copy the info next to IP Address, typically something like

To get your data, open your web browser and enter the IP address plus port 8080, for example: (include the backslash).

The exported data can be imported into a spreadsheet or another billing app, as many accept CSV and TSV files.

Sorth, the company behind Timewerks, provides documentation and screenshots so you can get a detailed feel for the app before deciding if it’s right for you.

If you love portable solutions, you’ll dig Timewerks. It’s available at the iPhone App Store for $4.99.
