GuitarStand for iPhone, iPad and Apple silicon Macs allows you to store data on your instrument collection. Data includes brand, model, serial number, body information, electronics, hardware, purchase information, and more. You can also add multiple photos of each instrument. Data syncs across your Apple devices and can be exported to a csv file and subsequently opened in your favorite spreadsheet program such as Excel and Numbers on any desktop device (e.g., Windows, Mac) as well as on mobile versions. GuitarStand is great for record keeping and can be helpful when getting your collection appraised or insured. Whether you are a professional musician, collector, or instructor, you can keep track of information on all your instruments.
