Thread Tracker 117 is a helpful iPhone application developed by Daniel Hotop to keep track of your DMC Art 117 Threads. With a total of 488 colors in the Article 117 range, includingvariegated and the new Oct 2013 colors, you can easily set the ownership status of each thread to "Don't own," "Do own," "On Bobbin," or "Need to Buy." The threads are presented by code and can be viewed in detail, including the number, color name, a sample of the color, ownership status, and the amount you own or need to buy.

The application features four buttons at the bottom that allow you to filter threads based on their ownership status, making it easy to view only the ones you need to buy or own. You can also search for threads by their code. By setting the mode on the threads you need to buy to "Need to buy" and deselecting "Don't," "Do," and "Bobbin," you can create a shopping list of the threads you need to buy. Thread Tracker 117 is a perfect tool for anyone working with DMC Art 117 Threads.
