ThreadBook is a comprehensive and user-friendly tool designed to help you manage your sewing, needlework, or embroidery threads. With a library of over 50,000 threads from more than 600 manufacturers, ThreadBook provides a seamless experience at your fingertips.

The app offers a range of features to enhance your thread management process. You can easily set your favorite brands to narrow down your matching choices and keep track of the threads you already have in your collection. Additionally, you can create a shopping list of threads you need for future projects.

Finding threads is made simple with ThreadBook. You can search for threads by their specific thread number, including partial numbers, or by matching a particular color. The app also allows you to use the camera on your device or a previously taken photo to find threads that match any color.

ThreadBook goes beyond just thread management. It offers a powerful conversion tool that instantly creates charts to convert any brand and type of thread to a matching color in any other brand and type. You can also create your own charts to find the best match for a specific brand in one or more other brands.

One of the standout features of ThreadBook is its ability to convert a list of thread colors, often provided with embroidery designs, to any brand and type. This feature saves you time and ensures accurate color matching for your projects.

With automatic updating of the thread library and synchronization of your collections between devices, ThreadBook provides a seamless and convenient experience for all your thread management needs.

ThreadBook is available on the iPhone platform and is licensed as a full version. Developed by Jim Stutsman, this lifestyle app is a must-have for anyone involved in sewing, needlework, or embroidery.
