Magnetometer vs Fettle

Magnetometer is a fun app for finding metal or magnets by detecting EMF interference with your iPhone's compass heading. Find your keys, or just have fun discovering what could be made of metal. Magnetometer is not meant to replace an actual, professional-grade metal detector. Magnetometer presents simple information to the user about the interference experiences. For more scientific data, please turn to other great apps on the App Store. Magnetometer is made for fun and for experimental purposes and is not designed for scientific use. Also, don't drop your iPhone in sand hoping to find treasure; it's risky.

Know what you own, where it lives, which batteries fit and what you need for the next job. Fettle is a private, cross-brand inventory for people who take their kit seriously. Photograph a power tool or hand tool and Fettle identifies the brand and model, then records its photos, serial number, purchase details and storage location. Your whole workshop, searchable in seconds. ADD A WHOLE KIT WITHOUT THE ADMIN Scan one item, a bench full of gear, or the box or manual from a multi-piece set. Fettle sorts the items for you. Receipt scanning can add the purchase date and price too. BUY FEWER BATTERIES See which batteries fit which equipment across Milwaukee, DeWalt, Makita, Ryobi, Bosch and more.
