BoltBuddy

BoltBuddy helps DIYers and homeowners identify and buy the correct screws, bolts, anchors, and washers without guesswork. You take a few photos next to a common reference (coin or included printable ruler), and the app estimates diameter, length, thread pitch, and head type, then suggests compatible options by project (drywall, studs, masonry, outdoor decking). It also warns about common failure points like wrong anchor type, over-torquing, galvanic corrosion, and load limits. The app generates a shopping list with exact spec language you can paste into any retailer search, plus a “bring-to-store” card showing dimensions and equivalents (metric/imperial). It’s realistic: accuracy won’t be perfect, so it includes a quick manual confirmation flow and a confidence score. Monetization is affiliate links and a small subscription for advanced project packs and offline catalogs.
