Meet the WiPry 2500x: a smart little tool that turns your iOS/Android device into a WiFi spectrum analyzer. It allows you to diagnose issues with your network, find busy channels, and identify any interference issues.
This WiFi spectrum analyzer works on both 2.4 & 5GHz bands. It supports the ZigBee protocol too. The device lets you monitor signal to noise ratio, view environment over time using waterfall mode, and track WiFi health.
