6月30日的SignalTracker应用程序分析

How good is the service from your current mobile provider? This app tells you by showing signal strength and download speed in all the locations that matter to you. You can use a second SIM to compare this to another provider. The results across are recorded on your mobile and in the Pro version they are shown in maps and graphs. You can also test your WiFi and decide whether to replace your fixed line with a mobile-only service. This is an ad-free app. Registration is not required, except in the Pro version.
