Need to test your Wi-Fi? Just use your phone.

Free to try: 60-second live sessions on iPhone and iPad, or a 3-day Basic or 7-day Pro trial on Mac.

As easy as a walk

Walk, test, assess.

It's as easy as taking out your phone and walking. nOversight tests the Wi-Fi as you go and shows signal, link rate and access point changes over the camera view. The blurred camera background keeps attention on the readings. Review any recording before sharing it.

Look beyond the bars

Good signal, slow Wi-Fi?

A strong signal does not always mean a good connection. Add the same phone’s Wi-Fi log to check retries, channel activity and roaming alongside your internet results.

Find the edge

Need better coverage?

Walk through the places where Wi-Fi struggles and see where the signal falls below your chosen requirement. Use the map to judge where an extra access point or mesh node would help, then test again after the change.

Share the air

Busy nearby Wi-Fi?

Nearby networks share the channel with yours, whether they belong to the flat next door or the office upstairs, and interference can make it busier. Add your phone’s Wi-Fi log to see when the channel was crowded before changing channel or moving your router.

Three ways to see your Wi-Fi

Walk and watch

See signal, link rate and access point changes as you move with your iPhone or iPad.

Add detail from the same phone

Import its Wi-Fi log to review retries, channel activity and Apple's roaming record.

Wi-Fi log import needs Pro.

Connect to your Mac

Inspect additional live measurements on a larger screen. Connect by USB or over a suitable Wi-Fi network.

For deeper investigation

Follow the finding.
Share the evidence.

Inspect charts and selected time windows on Mac. With Mac Pro, create a PDF report showing the result, test conditions and supporting evidence.

Before you start

Can I try it first?

Yes. On iPhone and iPad, the free version runs live sessions of up to 60 seconds. Basic removes the time limit, and Pro adds saved captures, Wi-Fi log import and CSV export. On Mac, Basic has a 3-day trial and Pro a 7-day trial.

Do I need to understand Wi-Fi?

No. Start with the summary and open the readings behind it when you want more detail. nOversight helps you investigate. Any change to your router or access points is yours to make, and you can test again afterwards.

Who sees my data?

Capture analysis runs locally, and you decide when to export or share a capture or report. Optional internet tests contact external services and are separate from that local analysis.

Do the phone and Mac share a licence?

No. iPhone and iPad subscriptions and Mac licences are separate. PDF reports need Mac Pro; the phone app exports CSV.

Which app to use
