Experience a handheld WiFi survey instrument with NetLens: Wifi Heatmap Survey, developed by DopamineFixx, built to map wireless coverage and identify interference in indoor spaces. The app uses ARCore visual-inertial tracking to anchor scans in three-dimensional space and renders a color-coded heatmap in real time as you walk. It supports 2.4GHz, 5GHz and 6GHz bands, accepts floor plan images, filters by AP, and exports PDFs, PNGs, or CSV data. IT professionals, network administrators, and tech-savvy home users gain diagnostic meters and professional reports without specialized hardware.

NetLens turns an Android phone into a handheld WiFi survey instrument

NetLens uses ARCore visual-inertial tracking to place WiFi readings in 3D space while you move, producing a color-coded heatmap that highlights dead zones and interference. The app analyzes 2.4GHz, 5GHz, and 6GHz signals and exposes live diagnostic tools such as a signal meter, a channel graph, and an access point browser. These elements combine to replace bulky laptop-based survey tools with a mobile workflow.

Does NetLens require special hardware or affect device operation?

The app runs on Android and its AR mapping requires a device that supports Google Play Services for AR (ARCore). Devices without ARCore can use a manual Floorplan mode to record readings by tapping an imported image. NetLens processes scans locally and operates offline with no mandatory account, so surveys and exports remain on the device rather than uploaded to a server.

Is NetLens safe to use on live networks and user devices?

NetLens stores scans, floor plans, and exported reports locally and does not force cloud synchronization, a design choice that preserves survey data on the device. The AR mode accesses camera and motion sensors, so the app requests those permissions during setup. Professional reports export as PDFs or raw CSV files on the device, letting administrators keep copies under their own control for compliance or archival needs.

Do you need technical skill to get reliable results from NetLens?

The app targets IT professionals, network administrators, and tech-savvy home users, and it offers both an automatic AR survey mode and a manual Floorplan mode for less-equipped hardware. Advanced filtering to isolate access points and frequency bands, plus the AP browser, favors users familiar with wireless diagnostics. Casual users can run simple scans, but extracting deployment-grade insights benefits from networking experience.

NetLens is a practical mobile survey tool best suited to technically minded users

NetLens delivers on-field heatmaps, AR-based motion tracking, and local report exports that help network teams spot coverage gaps and interference quickly. The app’s privacy-first design and multi-band support strengthen its use for site surveys. The principal limitation is hardware: ARCore compatibility is required for the automatic mapping experience, so planning surveys on unsupported devices requires the manual floorplan workflow.
