Read full description

XDiscovery finds the devices around your iPhone. The All tab searches Bluetooth and the local network together. Type in the search field to narrow the list. Bluetooth rows show the device name, signal bars, and the reading in dBm. Wi-Fi rows show the device name, its address, and the Bonjour service. The Bluetooth tab lists nearby Bluetooth devices. Named devices and the full count are shown at the top. Unnamed devices can be shown or hidden. Open a device to see a live ten-bar signal meter and the services and values it exposes, including battery level when the device provides it. The Wi-Fi tab browses Bonjour services on the local network. Pick a service type, then a device, to see its address and the details it advertises. Groups keeps the devices you care about. My Devices is ready to use, and you can add more groups. Add a device from its row or from its detail screen. While a saved device is nearby, its row is highlighted. Bluetooth devices in a group show live signal strength. XDiscovery only looks. It does not pair with devices, change their settings, or send commands. Groups stay on this iPhone.

Verdict

The call

The clearest difference is in-app purchases: XDiscovery at none against CodeInsight's 1. XDiscovery also leads on iOS requirement (15.0 vs 17.0). CodeInsight's advantage is update cadence (every 2 weeks vs every 30 months). On price, ads and device support there is nothing between them.
