SignalSeek: WiFi Heatmap
Dead Zone Finder, Speed Survey
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Walk your home once — SignalSeek maps every room while it measures real Wi-Fi quality, then turns both into a heatmap and a full PDF report you can act on.
SignalSeek is a Wi-Fi signal quality and coverage survey app: it maps your home as you walk through it, measures how your network actually performs in every room, and shows where coverage falls off.
No floor plan to draw. No measurements to type in. Walk through once and you get a coverage heatmap over your real floor plan, plus a full PDF report you can act on.
Please check your device: the floor plan needs LiDAR (iPhone 12 Pro and later Pro models, iPad Pro 2020 and later). Without it the app maps with the camera alone: some plan detail is missing and floors are aligned by hand. Wi-Fi measurements are unaffected. Works with any router or mesh system — nothing to install on your network.
HOW IT WORKS
1. Scan as you walk. Walk each room with the phone held up; the floor plan builds itself while network quality is measured at every step.
2. Mark your gear. Tap when you pass a modem, primary router, mesh node, wired AP or range extender. Coverage and backhaul are analyzed per device.
3. Read the map. 2D and 3D heatmaps show where coverage drops; the report tells you what to change.
WHAT YOU GET
• A coverage heatmap over your real floor plan, room by room
• Multi-floor projects with a whole-home 3D view
• Router and roaming analysis: which access point serves which area, mesh backhaul quality, hand-off between nodes
• Tap to inspect: any spot on the map shows its score, its room, the device covering it and the walls between
• What-if simulation: drag a router or add a node to preview coverage before you buy or move anything
• A full PDF report: coverage, speed, latency / jitter / packet loss, bufferbloat, app readiness (video calls, streaming, gaming), per-room detail and prioritized recommendations
• AI analysis export: structured data with definitions built in, ready for your favorite AI assistant
• History: every scan is kept in full, with a better/worse change map right on the heatmap to prove an improvement
• PDF reports in color or a black-and-white print edition, metric or imperial
• Never color alone: the map outlines each grade, hatches weak areas and gives every router its own pattern
FREE
Scanning, heatmaps, the whole-home 3D view and all on-screen results are free for up to 3 projects. No time limit, no ads.
PERSONAL (optional one-time purchase)
Pay once, keep it forever. Unlocks PDF and AI analysis export, history comparison with change maps, placement simulation, unlimited projects and iCloud sync across your own devices. Not a subscription; never charged again.
TEAM (optional annual subscription)
A shared project library for installers and IT crews: anyone can open and continue a project someone else scanned, with members and permissions managed by the owner. Hosted on your own WebDAV server, NAS, or an iCloud shared folder — we run no server of our own. Adds white-label PDF reports with your company name and logo, batch export, project templates and shared naming vocabularies.
PRIVACY
Your scans stay on your device. No account to create, no analytics. Floor plans, measurement points and reports leave the device only if you turn on iCloud sync yourself, or point the app at your own WebDAV server or NAS — and then only there.

• Simulate placement: drag routers or add nodes to preview coverage before touching hardware
• The sample project now has everything unlocked — try it all before buying
Ready for iPhone Duo: unfold it to see your projects and results side by side.
