Great Beginning – WiFi Guard - Scan devices and protect your Wi-Fi from intruders Review

It does what it says it will as far as monitoring devices on a wireless network and sends notifications when a new device logs on. It naturally does not have Be ability to block devices since that is handled through your router. It would improve the functionality of multiple iOS devices with the app installed could shared custom names as it is each instance of the device must be manually kept in sync. Pulling information reliably would be nice as well such as MAC addresses. This would allow for blocking that MAC on the router.
