WiFi Heatmap 3D : Signal Map

Your Wi-Fi has a shape. See where it works for you.

WiFi Heatmap 3D : Signal Map turns a walk through your space into a visual Wi-Fi coverage survey. Measure signal strength, explore a 3D room plan or 2D heatmap, and find the corners where your connection needs attention.

Whether you are choosing a desk for video calls, checking a gaming corner or comparing rooms at home, start with the signal you can actually measure.

MAP YOUR WI-FI, ROOM BY ROOM
• Walk through your space while the app samples Wi-Fi signal strength.
• Choose a quick room-level survey or a more detailed continuous scan.
• Use ARCore position tracking on compatible devices to place measurements in your room.
• Explore your survey in 3D and view coverage as a color-coded 2D heatmap.
• Spot stronger and weaker measured areas, follow your walking path and review router-placement suggestions.

UNDERSTAND THE CONNECTION
• Read live signal strength in dBm and follow changes on a signal graph.
• Inspect nearby Wi-Fi networks, frequency bands, channels and access points.
• Compare channel overlap and review connection and device capabilities.
• Check Wi-Fi security indicators and discover responsive devices on your local network.

TEST BEYOND SIGNAL BARS
• Run download and upload speed tests.
• Check latency with ping and investigate DNS connectivity.
• Add optional throughput measurements to a walking survey.
• Review access-point changes and roaming observations where your device provides the data.

SAVE WHAT YOU DISCOVER
• Keep a local survey history and revisit earlier measurements.
• Add optional landmark photos and labels to remember useful spots.
• Export a heatmap image or share a written survey report.
• Choose light, dark or system appearance, accent colors, and English or Indonesian.

FREE TO USE, OPTIONAL AD REMOVAL
The app is supported by ads. Banners appear on selected browsing and result screens; occasional full-screen ads appear at a natural break after completed surveys. Ads do not interrupt an active room scan. An optional one-time Google Play purchase removes in-app ads. Restore your purchase using the same Google Play account. Your local price is shown before checkout.

BEFORE YOU SCAN
AR room scanning requires an ARCore-compatible device and Google Play Services for AR. Camera and location permissions are needed for relevant scanning features. Available Wi-Fi details, scan frequency and measurement precision depend on Android, your device and the environment. Walls and unsampled coverage may be estimated. Router suggestions are guidance, not a guarantee of better speed. This app measures and analyzes Wi-Fi; it does not boost radio power or reveal Wi-Fi passwords.

Speed tests use internet data and Cloudflare endpoints. Inspect only networks you own or are authorized to test. Surveys and landmark photos are stored on your device; ads, purchases and network tests use the third-party services described in our privacy policy. Sharing sends the selected report or image to your chosen destination.

Make your Wi-Fi visible. Find your better spot.
