NetLens: Wifi Heatmap Survey análises de aplicativos para 7 de agosto

NetLens turns your phone into a handheld Wifi survey instrument. Walk a space - an apartment, an office, a warehouse - and watch a real-time signal heatmap form beneath your steps. THREE WAYS TO MAP - Heatmap survey: hold the phone in front of you and walk. The rear camera supplies visual-inertial tracking - the same simultaneous-localization machinery that powers ARCore - so every Wifi scan is anchored in 3D by the phone's own motion. No floor plan to upload, no account, no markers on the walls. The map fills in along the path you walk. - Quick Scan: a live AR mode for a fast look. Wifi readings appear right in your camera view as you move, with no setup and nothing to save. - Floorplan: no camera required. Import a floor plan, sketch, or screenshot of your space, then walk and tap to drop readings and build a heatmap by hand. WHAT YOU GET - Live heatmap that grows as you move, color-graded from weak to excellent signal - Filter the map to a single access point, or to one band (2.4 / 5 / 6 GHz) - Adjustable map layers: heatmap, walk path, photos, and an underlaid floor plan you can fade to line up with real rooms - Color palettes including a colorblind-friendly option - Photo markers placed on the map and carried into the PDF - Export a clean PDF report, a PNG image, or raw CSV samples - Group scans into projects and export a whole multi-floor building as one combined PDF - Extra live tools: Signal Meter, Channel Graph, AP Browser, Connection, and a Speed Test with saved history PRIVACY Everything you capture stays on your device - Wifi scans, photos, notes, and exports never leave the phone until you choose to share them. No account and no cloud, and no behavioral profiling or tracking tied to your identity. The only data that leaves the phone is anonymous, opt-out usage analytics (you can turn it off in Settings) and, on the free tier, the ad requests behind the banner. NetLens uses location permission only because Android requires it to scan for Wifi; it reads nearby networks and, if you leave location on, stamps a scan with a coarse position so it remembers which building it came from - and even that stays on the phone. FREE AND PRO The free tier covers 1 project, 3 saved scans, 2 floorplans, and 5 Quick Scans a day, with PNG and CSV export plus a full in-app preview of the PDF report. Every live tool - Signal Meter, Channel Graph, AP Browser, Connection, Speed Test - stays unlimited. Free shows a banner ad on the browsing screens and a small watermark on PNG exports; a short ad clears it on a single export. One-time Pro (no subscription) lifts every cap and unlocks the professional PDF report and full CSV, with no ads and no watermark. Anything you already created stays fully viewable and exportable on either tier. REQUIREMENTS Quick Scan and the walking heatmap need a device with ARCore (Google Play Services for AR) support and a working rear camera. The Floorplan tool works on any supported device.
