Key Library vs Crow & Rodent Sounds

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.

A simple player for exploring how birds and urban rodents respond to sound. Choose from nine saved recordings and a playback duration. The offline guide illustrates eight crows and pigeons plus Norway rats, roof rats, and house mice. The free version includes three 10-second plays per day, reset when the device's local date changes. A one-time Premium purchase unlocks continuous playback, up to nine layered sounds, and a Random button that switches among the nine recordings. Sound labels follow the saved recordings. Species, behavior, and deterrent effects are not verified by a filename. Owl calls may attract crows, and rodent responses vary by species and setting. Use a safe volume and consider nearby people and animals. All nine recordings may be tried for crows; only the owl recording is presented for rodents. Crows and rodents can learn, so repeated sound may draw a weaker response. For crows, we recommend Premium Random playback or layering up to nine sounds. Results are not guaranteed. After using the free plays, you can choose to watch a rewarded ad to restore three plays.
