Openband: WiFi Analyzer
Wi-Fi channel & signal scanner
Only for Mac
Free · In‑App Purchases
Mac
Your Wi-Fi is acting up. You want to know three things:
WHICH CHANNEL SHOULD I BE ON?
Openband tells you in a sentence, seconds after launch: "You're on channel 11 with 4 neighbors. Channel 1 is clearer — move there." And when your router already picked well, Openband is the rare app that says so: "You're already on the best channel. Stay put."
WHO ELSE IS OUT THERE?
A clean list of every network around you — name, band, a five-bar signal and a plain word (Excellent, Good, Fair, Weak), security. Mesh systems are grouped so they read as one network, not six mystery rows.
WHERE SHOULD THE ROUTER GO?
Open Walk Around, mark the spot where you're standing, and walk. One big readout tells you whether each spot is stronger or weaker than where you started. Find the dead zones. Find the good shelf.
ALL OF THAT IS FREE. Forever. Unlimited scans, no account, no ads, no watermark, no trial countdown.
The recommendation is built properly:
• It only ever suggests channels 1, 6 or 11 on 2.4 GHz — the non-overlapping trio.
• It weighs loud neighbors more than distant ones.
• It handles DFS radar channels honestly — included, explained, and you can exclude them.
• It ignores your own mesh points, so they don't penalize their own channel.
• It only tells you to move when the move is clearly worth reconnecting every device in the house.
OPENBAND PRO — one purchase, once. For those who have know. ($14.99, Family Sharing included)
• dBm everywhere — exact signal numbers, noise floor and signal-to-noise for your connection, transmit rate, Wi-Fi generation.
• The channel-overlap spectrum — every network drawn across the frequencies it actually occupies, with real channel widths.
• "Why this channel" — the congestion scoring behind every recommendation, in the open.
• Per-radio drill-down — BSSIDs and the per-band breakdown of multi-radio routers and mesh nodes.
• Signal over time and a roaming log — catch the moment your Mac clings to the weak upstairs access point at −78 dBm.
Our promises, in writing:
• No subscription. Ever.
• Nothing that is free today ever moves behind the paywall.
• The unlock is honored forever, on every future version.
• No ads, no analytics, no telemetry. Openband contains no networking code at all — your scans physically cannot leave your Mac.
Openband needs macOS Location Services permission to list nearby networks. That is a macOS rule because network names can reveal where you are and it is the only reason the permission dialog appears. Openband never requests, reads, or stores your location.

Sharper App Store listing and small fixes. Your best channel is still free, in a sentence.
