Wi-Fi Analyzer & Heatmap · macOS

Raven

See the air around you. Import a floor plan, walk your space, and Raven maps coverage room by room in real feet — then scans every nearby network, shows the spectrum live, and tells you the clearest channel to use.

◆ macOS 14+ ◆ Apple Silicon native ◆ Built with SwiftUI

What Raven does

Everything you need to diagnose and plan a Wi-Fi network.

Live spectrum view

Watch every AP drawn across the frequencies it actually occupies on 2.4, 5, and 6 GHz — instantly see who's stepping on whom.

Smart channel advisor

A signal-weighted score ranks every channel and recommends the best one — counting co-located SSIDs on a radio only once.

Network detail

Per-network RSSI, channel, width, security (WPA3/WPA2/OWE), vendor, and approximate Wi-Fi generation — sorted by signal.

Coverage heatmaps

Import a floor plan (or use a blank canvas), walk your space, and Raven paints a signal heatmap — multi-floor supported.

Walk surveys & timeline

Record a walk to capture peak signal everywhere you go, and watch RSSI-over-time per radio to chase down drops and dead zones.

PDF site surveys

Export a multi-page report — a per-band channel plan listed in deployment order, composited heatmaps for every floor, and dead zones in square feet.

What's new

Signal reported for the device that will actually use the space, surveys measured in real feet, and a manual built into the app.

See what a phone sees

Your Mac is a better Wi-Fi client than a phone in someone's hand — more room around its antennas, and no fist wrapped around it. Raven now reports every signal the way a handheld would receive it, so you plan for the devices people actually use.

Switch without surveying again

Measurements are always stored as your Mac read them. Change the profile on a finished survey and the map redraws on the spot — and every report states which client it was written for.

Set the scale, work in feet

Drag a line along any known dimension — a dimension string, a wall, the drawing's scale bar — and enter its real length. Raven learns how big the plan actually is.

Check your calibration

Drag along a second known dimension and Raven shows the measured length as you go — so a vertical and a horizontal reading can be confirmed before you survey.

Dead zones in square feet

Reports state weak coverage as an actual area instead of a sample count — the number a client or a landlord will understand.

A manual, built in

Press ⌘? for a searchable handbook covering every part of the app — how the channel score works, how to calibrate a plan, and what to look for in a signal measurement.

A look inside

Real captures from Raven running on macOS.

Raven coverage heatmap on an office floor plan, each marker labelled with two networks, their signal in dBm, and their channel — **Coverage heatmap, with the numbers.** Import a floor plan — a PDF blueprint works — and walk the space dropping a marker in each room. Raven paints live coverage and labels every spot with each network it heard, its signal, and its channel, reported for the client you're planning around.

Survey for a phone, not your Mac. Pick the client you're planning for and every signal is shown the way that device would receive it — 4 dB off on 2.4 GHz, 6 on 5, 9 on 6, because the physics differs by band. Measurements stay as your Mac read them, so switching profiles redraws a finished survey instead of costing you another walk.

Raven 5 GHz analyzer with a network selected, showing a per-radio channel plan for its two 80 MHz radios, one marked with the eight neighbouring radios heard near it — **A plan, not just a picture.** Select a network and Raven lays out every one of its radios — what each is on now, how wide it is running, and where it should go. Record signal history first and each radio is planned against the neighbours heard near it, so an access point at one end of a building isn't moved for congestion it never sees. Name your own access points once and those names follow them across every band.

Raven 2.4 GHz analyzer showing suggested channels 1, 6 and 11 listed in channel order with channel 6 marked clearest, and seventeen networks recorded elsewhere drawn as dashed outlines — **See the congestion.** On 2.4 GHz the pile-up is obvious at a glance, and the advisor scores every channel against it — weighted by how loud each neighbour is, and with your own access points left out, because your router is not a reason to move your router. Suggestions are listed in channel order so they line up with the graph above them, and networks Raven recorded elsewhere in the building are drawn as dashed outlines — they can't be heard from here, but they still count.

Raven exported PDF site survey summary showing a per-band channel plan: how wide each band is running, how many channels it has, which need DFS, and the channels ranked in deployment order — **Exportable site survey.** One click turns your walk into a shareable PDF. Every band gets a plan followed by a coverage map for every floor. Good for a before and after, or just client reassurance that the job is done.
