I'm the developer. Some of you saw my earlier posts about DeviceShelf, the local-first network scanner with a headless server edition. The iOS app just cleared App Store review, so you no longer need TestFlight to run it.
It's the same scanning engine as the desktop app: network scan, device identification, open ports per device, a security report, presence alerts, and export/share from the phone. Apple's multicast entitlement is active in this build, which means SSDP/UPnP discovery works on iOS as well.
The download is free with a trial. Full features unlock with a DeviceShelf license (one license covers desktop, mobile and server) or through an in-app purchase. Scans stay on the device; the AI device ID is bring-your-own-key.

Still a young app. If it mislabels something on your network, tell me and I'll fix it.
