Main Street Strong™SignalBench by PayDivy.
Three live tests, run right here on your device: cellular link strength, QR camera lock-on plus page load, and contactless tap speed. Your test data stays on your device, we only email the report to the address you give us.
Result levels
Each test is graded against the same four-point scale. Use it to compare signal, QR, and NFC results.
Run the tests on your phone
Load SignalBench on a separate device. Scan the QR code with your phone, or click Copy link and paste it into a new browser window.
Cellular signal & link quality
Reads your device's live network profile and fires repeated round-trip probes to measure real latency and jitter.
Your browser doesn't expose the Network Information API — latency probes below still work.
Signal changes room to room. Name a spot, run the test, then walk somewhere else and run it again — every run is saved below so you can compare.
No spots saved yet. Your first run will appear here.
QR lock-on + page load speed
Two-stage test: how fast the camera locks onto a QR code, then how fast the device loads the heavy content page behind it.
Scanned links are timed over the network, so sites that block embedding still get a load time. Tap a result to open the link.
NFC payment speed
Times a full contactless transaction: how long your phone takes to detect and read the tag, plus the authorisation leg.
Hold a contactless card or tag against the back of your phone.
