Guitar Guru
Guitar Collecting & Valuation
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Guitar Guru is a guitar collection and valuation app. It uses a powerful machine learning model to value any guitar. Being able to get a neutral valuation is a great thing, because normally everyone who values a guitar has a reason to be biased. This is obvious in the case of shops and private sellers, but online marketplaces also have every reason to try to subtly drive up prices at every turn. There are valuation books for guitars, but these become out of date quickly, and are unable to combine every piece of information about a specific guitar into a valuation. Guitar Guru creates a starting point for any negotiation that is data-driven and fair. In addition to that, it's a place to track your collection so you have all the information to hand. This can be valuable if you want to insure your collection, or a guitar is stolen.
