Everyone has a drawer, hook, or junk bin full of keys with no idea what they open. Key Library solves that — permanently. PHOTOGRAPH EVERY KEY ONCE Snap a photo of any key — house, garage, padlock, filing cabinet, mailbox — and add a quick note about what it opens. Key Library automatically reads any stamped code on the key and keeps a smart visual fingerprint of its shape and cut pattern. FIND OUT WHAT A MYSTERY KEY OPENS Found a key with no idea what it's for? Scan it with Identify Key, and Key Library checks it against everything you've already saved — flagging Exact and Likely matches so you know at a glance whether you've seen it before. BUILT FOR REAL KEY DRAWERS Works regardless of how the key is rotated or flipped when you scan it Organize by Automotive, Household, or Commercial Search and filter by notes, tags, category, or detected key codes Add a photo of both sides for extra-reliable matching ENTIRELY PRIVATE, BY DESIGN Key Library has no account, no login, and no cloud. Every photo, note, and match happens right on your iPhone using Apple's on-device Vision framework — nothing is ever uploaded anywhere. Your key drawer stays exactly as private as it already is. Free to start — catalog your first several keys at no cost, with a simple one-time upgrade if your collection grows. Stop guessing. Start knowing what every key in that drawer actually does.

The clearest difference is in-app purchases: ASC at none against Key Library's 2. ASC also leads on iOS requirement (12.0 vs 18.6). On price, ads and device support there is nothing between them.
