I have provided two versions: a Professional Version (suitable for blogs or formal feedback) and a Quick User Version (suitable for the App Store review section).

5. Additional Utilities

OUI Lookup: A manual tool to look up MAC addresses to find hardware vendors.
WiFi Connection Details: Displays the device's current internal IP, Gateway IP, DNS, and Lease duration.

2. The Access Point List

This is a raw data table. It shows every network broadcasting within range, sorted by signal strength (strongest first). Columns include:

SSID: The network name.
BSSID: The unique MAC address of the router.
Channel: The frequency used.
Security: WPA2 vs. Open.
Vendor: Often interesting (e.g., "Cisco," "TP-Link," "Apple").
