WhiteSail

Compare five-second Wi-Fi and cellular checks at places you test yourself, so you can choose a better spot for gaming, video, and calls.

See how the current connection feels, test the places where you actually use it, and compare responsiveness, variation, and interruptions without treating Mbps as the whole story.

Compare places you tested

Understand how the current connection feels.

While WhiteSail is open on the Live tab, it continuously updates experience signals for the Wi-Fi or cellular connection you are using.

  • Focus on responsiveness, variation, and interruptions
  • Use the current experience as a practical starting point
  • See whether the connection looks steady enough for the moment
  • Do not confuse the result with an Mbps bandwidth test

Run a short check where you actually use the network.

Choose a real place such as your bed, desk, sofa, hotel room, or café seat, then run a check of about five seconds.

  • Select a suggested place or enter your own name
  • Test the exact spot before gaming, video, or a call
  • Save the result to the place you selected
  • Repeat a saved place when conditions change

Compare the places you have personally tested.

Saved results stay grouped by the current Wi-Fi or cellular connection, so unlike networks are not casually mixed together.

  • Compare familiar places on the same connection
  • Measure another place before drawing a conclusion
  • Retest a saved place from its detail screen
  • Use the result to choose—not to claim stronger coverage

Measurement boundaries

Know what WhiteSail can—and cannot—tell you.

WhiteSail measures response, variation, and interruptions at places you test. It does not measure Mbps, scan nearby signals, strengthen coverage, or predict an untested place.
