WiFi Heatmap - The GPS Based Wi-Fi Signal Heatmap Generator
Stop guessing and start seeing your network. WiFi Heatmap transforms your phone into a powerful, professional-grade signal mapping tool. By plotting your Wi-Fi strength (RSSI) as color-coded circles on a live Google Map, you can instantly visualize your network's true coverage, pinpoint dead zones, and optimize your setup like a pro. This is not just another signal plotter. We go beyond simple GPS tracking with advanced features for unparalleled accuracy: * **Advanced GPS Smoothing:** We use a sophisticated Kalman filter that models your position *and* velocity. This smooths out erratic GPS jitter for a clean, accurate map. * **Compass-Aware Filtering:** The app intelligently uses your device's compass bearing. GPS points that radically disagree with your direction of travel are penalized, resulting in superior tracking accuracy, especially when moving. * **Live Status Dashboard:** The top status bar gives you a complete picture, showing your current SSID, BSSID, RSSI (dBm), live GPS accuracy in meters, and map zoom levels. **Total Control Over Your Map & Data** WiFi Heatmap is built for flexibility, whether you're doing a quick check or a detailed site survey. * **Three-State Auto-Pan:** A dedicated button cycles through three tracking modes: 1. **Manual:** Full manual control of the map. 2. **North-Lock:** The map centers on your location, with North always "up." 3. **Compass-Lock:** The map centers *and* rotates to match your device's bearing. * **Pause & Erase Mode:** Tap the pause button to stop recording data. This activates "Erase Mode," allowing you to tap any circle on the map to remove individual, incorrect data points. * **Save Screenshots:** Instantly save a high-quality screenshot of your current map view directly to your device's public "WiFiHeatmap" gallery folder. **Powerful Session Management** Never lose your work and build on past surveys with a complete session history. * **Save & Review:** Save your entire heatmap (all data points and a thumbnail) to your personal session history. * **Resume & Add Data:** Load *any* saved session from your history and resume mapping. This allows you to add new data points to an old survey. * **Full History Control:** Manage your list of saved sessions with multi-select, "Select All," and "Delete Selected" options. * **Automatic Crash Recovery:** If the app closes unexpectedly, your unsaved work is safe. On the next launch, you'll be prompted to either resume your unsaved session or start fresh. **Deep Customization** Fine-tune the app to fit your exact needs from the detailed Settings screen: * **Visuals:** Adjust the **minimum and maximum circle radius** to customize the heatmap's appearance. * **Performance:** Control the **location update interval** to balance between a high-detail map and battery consumption. * **Data Quality:** Set a **GPS accuracy threshold** (in meters) to automatically ignore and discard low-quality location data. * **Usability:** Manually override the system's **light/dark theme** and set your preferred **minimum map zoom** level. * **Smart Overlays:** The app automatically informs you if you're in Airplane Mode, have no internet, or if Wi-Fi is disabled, so you're never left guessing. Whether you're a network administrator, a tech enthusiast, or just someone trying to eliminate a frustrating dead spot, WiFi Heatmap gives you the advanced tools you need to see your wireless world.
