Thread Tracker 4635 is a simple application designed to help you keep track of your Anchor Art 4635 Threads, it features all 494 colours in the Article 4635 range, including the new variegated range. The application allows you to set 'ownership status' of 'Don't own, Do own, On Bobbin and Need to Buy' per thread. Each thread is presented sorted by Code, with the ability to view a detail page which tells you the number, the colour name, a sample of the colour, view and modify the 'ownership status' and view and adjust the amount you own/need to buy. 4 buttons down the bottom of the application allow you to easily filter out/in threads based upon 'ownership status', allowing you to view only the ones you need to buy, or own easily. A search feature allows you to find threads by their Code. By setting all 'ownership status' to 'Need to buy' of the threads you wish to buy and pressing the 'Don't', 'Do' and 'Bobbin' button so they are in the deselected state, you will be left with a list of 'Need to buy' and hence have a Shopping List.
