Wi-Fi analyzer with channel graph, signal meter, speed test and diagnostics.
Wi-Fi Doctor turns your phone into a proper Wi-Fi instrument. It shows you what your signal bars will not: which channel your neighbours are crowding, how much noise margin you actually have, and whether the problem is your Wi-Fi at all. EVERYTHING IN ONE APP • Overview — SSID, BSSID, RSSI, tx/rx link rate, frequency, channel width, Wi-Fi standard (4/5/6/6E/7), security, IPv4 and IPv6, gateway, DNS, DHCP lease, MTU, MAC randomisation and internet validation, all live. • Signal meter — a live dial, a signal trend over the last minutes, min/avg/max, variation, noise margin (SNR) and a free-space distance estimate. • Channel analysis — the classic spectrum graph, drawn across the channels each access point really occupies, plus a measured per-channel load and a concrete "move to channel N" recommendation. • Networks — every access point in range with search, sorting and band filters, and a detail sheet with occupied channels, centre frequency, vendor, observation history and raw capabilities. • Time graph — track up to eight networks side by side to spot roaming, interference bursts and dead spots. • Speed test — download, upload, latency, jitter and packet loss, with the result compared against your negotiated link rate. • Device discovery — sweep your subnet for other devices, with MAC vendor, hostname, mDNS services and a per-device port scan. • Diagnose — nineteen automated checks with a weighted health score and a specific fix for anything that fails. • Coverage survey — walk your home, record a reading per room, and see exactly where the weak spot is. • Live throughput — real-time down/up rates and session totals. • Tools — ping, traceroute, DNS lookup, port scanner, subnet calculator, Wake-on-LAN and public IP/ISP lookup. • History — every speed test, health score and daily signal is kept on the device, so you can answer the question every fault report raises: was it always like this? • Shareable report — a plain-text summary plus a CSV of every access point in range, ready to paste into an email or a support ticket. • Measured distance — where an access point supports 802.11mc ranging, the distance is measured by time of flight instead of estimated from signal strength. • Floorplan coverage — drop each survey reading onto your own floorplan image and see the weak area; the space between pins is clearly marked as interpolated rather than measured. • Shortcuts and tablets — long-press the icon to jump straight to Diagnose or the speed test; on a tablet the navigation moves to a side rail. BUILT FOR READING, NOT GUESSING Charts use a colourblind-safe palette, always carry a legend and direct labels, and every derived figure is labelled as an estimate. Where Android does not expose a value — the radio's real noise floor, for example — the app says so and shows you the assumption it used, which you can change. MAKE IT YOURS The bottom bar is fully configurable: pin any three to five destinations in any order, and reach everything else from More. Light and dark themes, optional Material You colours, dBm or percentage, metric or imperial. TEN LANGUAGES English, 中文, हिन्दी, Español, Français, العربية, বাংলা, Português, Русский and اردو — with full right-to-left support. PRIVACY Every measurement happens on your device. Nothing about your networks is uploaded, and there is no analytics SDK. The only features that contact a third party — the speed test and the public IP lookup — run only when you tap them.
