WiFi & Internet Speed Test

WST WiFi Speed Test is an internet speed test for Android that helps you understand how your connection performs. Measure download speed, upload speed and ping on home WiFi, public WiFi or mobile data. See your results in a clean interface, compare tests over time and explore advanced connection diagnostics with Premium Lifetime. Run a quick speed test when a video buffers, a game feels laggy, a call breaks up or a new router does not perform as expected. WST measures the connection between your device and a test server, so you can compare different rooms, networks, times of day and server choices. What you can measure • Download speed (Mbps): how quickly your device receives data. • Upload speed (Mbps): how quickly it sends data. • Ping / HTTP latency (ms): how long a test endpoint takes to respond. • Jitter: variation between initial latency measurements, available with Premium Lifetime. • Ping loss: unanswered replies in an ICMP probe sample, available with Premium Lifetime. If your device or network blocks ICMP, the result may be unavailable rather than zero or 100%. • Loaded latency: response times measured during download and upload, shown in the Premium latency chart. Choose a server that works Use automatic server selection to check available test endpoints before a run. If a server fails or limits requests, WST can try another suitable endpoint when one is available. You can also select a server manually to compare results. Server availability, routing and network conditions can affect every measurement. Test history and export Your speed test history is stored locally on your device. The free version keeps up to 10 recent results; Premium Lifetime increases the limit to 50 and unlocks CSV export. Save a copy of your results for your own records or compare changes after moving a router, switching WiFi bands or changing your internet plan.
