KeyMatch Pro helps you build a searchable visual library of your keys so you can identify, organize, and manage them with confidence. • Capture clear key photos • Identify an unknown key by matching it to your saved library • Track key quantity, key codes, and custom tags • Search and filter keys by name, code or tag • Check for possible duplicates when adding a key as an option • Export a key audit report for records and reviews • Back up, transfer, import, and export your key list • Keep access secure with in-app security options • New plans are one-time purchases. Existing subscriptions remain supported. Sharing with a team: One person can maintain the main key library and share a backup copy with others. Team members can import that backup to view, search, identify, rename, and manage the shared key list on their own device. A paid plan is only needed when a user wants to add more keys beyond their plan limit or unlock paid tools on their own device. KeyMatch Pro does not use cloud sync or shared online accounts. Sharing is done manually through exported backup files. Ideal for homeowners, locksmiths, property managers, facilities teams, and anyone who manages lots of keys.

Verdict
The clearest difference is monetization model: KeyMatch Pro at free with in-app purchases against Increase Volume's subscription. KeyMatch Pro also leads on device support (3 vs 1). Increase Volume's advantage is update cadence (every 6 days vs fortnightly). On price, rating, ratings volume and ads there is nothing between them.
