About this app

Check your network environment in detail with "SpeedChecker"!

SpeedChecker is a simple yet highly functional speed test app that quickly measures download and upload speeds with a single tap. Beyond just speed measurement, it automatically records your connected carrier information, communication method, and even the measurement location's address.

Main Features:
