Accurate Mobile & WiFi Speed Test
Slow internet can be frustrating. The ToolZaro Speed Test is designed to work perfectly on your Android or iPhone as well as your desktop. We measure how fast your device can communicate with the internet in real-time.
What do these numbers mean?
Download Speed
How fast content loads (e.g. streaming YouTube, scrolling Instagram). Higher is better.
Upload Speed
How fast you send data (e.g. sending WhatsApp videos, backing up photos). Higher is better.
Ping (Latency)
The delay in connection. Essential for online gaming. Lower is better (under 40ms is great).
