DK WiFi Survey

Measure and log the signal strength (RSSI) of the Wi-Fi network you are connected to, once every second. Use it to find the best spot for your router, to place an extender or mesh node, or to check why one room keeps dropping.

WHAT YOU GET

• Large RSSI readout in dBm, with signal quality (%) and a color-coded rating: Excellent / Good / Fair / Weak
• Live signal graph (1 min / 5 min / all), with an adjustable reference line (default -67 dBm)
• Roaming markers on the graph when you move to a different access point
• Device info: IP address, subnet mask, default gateway, DNS servers and supported Wi-Fi standards

PRO (ONE-TIME PURCHASE)

• Full details: BSSID, vendor, band and channel, Wi-Fi generation and standard, noise and SNR, Tx/Rx rate, average, min and max
• Heatmaps: draw walls and labels on a photo of your floor plan or a blank grid, tap where you stand to take a reading, and see strong and weak areas in color. Save or share the result as an image
• Save readings with a location note and compare them in History
• Export time series and history as CSV

BEFORE YOU START

• Requires iOS 17 or later. Measurements use Apple's built-in Shortcuts app. Add the included shortcut from the button in the app
• Only the Wi-Fi network you are currently connected to (one access point) can be measured. Because of iOS restrictions, the app cannot list nearby networks or survey channel usage
• Keep the app on screen while measuring. Switching to another app stops the measurement

PRIVACY All readings, floor plans and history stay on your iPhone. Nothing is sent anywhere, and there are no ads.
