See where your Wi-Fi actually reaches

If a reading looks wrong, a map doesn't match what you're seeing in your space, or something just isn't working the way you'd expect, tell me what you did and what happened. That's the fastest way to get it fixed.
Start a recording, then walk through the space you want to map. WiFiMap pings your router and tags each reading with your location as you go. Pause and resume freely — a paused recording doesn't lose what you've already captured. When you're done, save the result as an image from the gallery.
WiFiMap places readings using your phone's GPS, which is built for outdoor, open-sky accuracy — typically a few meters. Indoors, especially near walls, metal appliances or upper floors, GPS accuracy gets worse, so a map can look stretched or offset compared to the room it describes. This is a limit of GPS itself, not something WiFiMap can correct for. Recording near a window, or taking a slower pass, generally helps.
Because it isn't measuring that. WiFiMap measures the connection between your phone and your router — signal strength and reachability from where you're standing — not the speed your internet provider delivers to that router. A weak-signal spot on the map means Wi-Fi struggles to reach there, regardless of how fast your internet plan is.
Each hex cell reflects the Wi-Fi readings recorded near that spot — strong signal, weak signal, or unreachable. Gaps in the grid are places you haven't walked through yet with a recording running.
