WaveCheck listens to every Wi‑Fi network and Bluetooth device your Mac can hear, adds up your exposure and shows how far below international safety limits you are.
7 days free · One-time purchase · macOS 14 Sonoma or later · Apple Silicon & Intel
No extra hardware. WaveCheck uses the Wi‑Fi and Bluetooth radios already in your Mac.
Your total exposure in µW/m², updated every few seconds, on a scale that runs all the way up to the safety limit.
A clear yes or no on whether your level is a concern, based on what the research actually shows rather than on fear.
See which channels are crowded on 2.4, 5 and 6 GHz, and which network is yours.
Routers, phones, earbuds, watches and more, with signal strength and each one's share of your exposure.
Walk around your home or office with your Mac and watch the graph to see where signals are strongest.
Estimate exposure from devices the meter can't see, like your own phone or earbuds, at any distance.
✓Not at everyday levels.
WaveCheck doesn't sell fear. It shows the measurement, compares it with the international limit and explains what the science says.

A busy room usually reads tens of thousands of times below the limit. WaveCheck shows exactly where your room sits.
WaveCheck is an estimate from your Mac's radio, not a calibrated meter or a medical device.
The method is fully transparent and shown inside the app.
Your Mac reports how strongly it receives each Wi‑Fi network and Bluetooth device (RSSI, in dBm).
Each signal is converted into power density (µW/m²) using its frequency and the antenna's effective area.
All sources are added up and compared with the ICNIRP 2020 / FCC public limit of 10 W/m².
Try it free for 7 days. Buy once and keep it.
WaveCheck is sold directly, not through the App Store, so macOS asks you to approve it once. It takes about 30 seconds.
Open WaveCheck.dmg and drag WaveCheck into your Applications folder.
Double-click WaveCheck. macOS says it can't verify the app. Click Done.
Open System Settings › Privacy & Security, scroll down and click Open Anyway next to WaveCheck.
Click Open Anyway again and enter your Mac password. That's it: it opens normally from now on.
On first launch WaveCheck asks for Bluetooth access (to hear devices) and Location access (macOS requires it to show Wi‑Fi network names). Your location is never used or stored.
Not yet. iOS doesn't allow any app to scan nearby Wi‑Fi networks, so a full version isn't possible on iPhone. Be wary of iPhone "EMF meter" apps: most read the compass sensor, which can't detect Wi‑Fi at all.
No. It's a well-founded estimate that uses your Mac's built‑in radio. It's great for comparing rooms and understanding your environment, but it isn't a calibrated instrument for compliance testing.
No. Measurements stay on your Mac. The only thing sent over the internet is your license key, when you activate it, to confirm your purchase.
macOS only reveals Wi‑Fi network names to apps with Location permission. WaveCheck never reads or stores your location, and measurements still work if you decline (networks just show as "Hidden name").
On the old Mac, open WaveCheck › License… and click Deactivate. Then enter the same key on the new Mac.

Any Mac with Wi‑Fi and Bluetooth running macOS 14 Sonoma or later, on Apple Silicon or Intel.
