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.
