Signl checks download speed and latency where you actually use WiFi, then maps the rooms you measured. See the test point, Mbps and ping behind the weak connection.
Free to download iPhone, iOS 18 or later Works with or without LiDAR
Four steps, from a room you have never measured to a survey you can hand to somebody else.
With a LiDAR-equipped iPhone, move through the home while Signl captures walls and furniture. On other supported iPhones, the app automatically uses a flat walked coverage map instead.
Snap a photo of your floor plan or drop in a PDF. Signl finds the rooms, the doors and the windows, then builds the same 3D home from that. Floor plan import is a Signl Pro feature, not a requirement for iPhones without LiDAR.
The room survey records download throughput and latency where you stand. A separate speed test also measures upload, so you can inspect all three without presenting an invented RSSI value.
The report includes the home map, rooms measured, median and slowest download readings, median ping, sample count, recommendations and any saved photos. Share the PDF with the person helping you troubleshoot.

A survey tool that fits in your pocket and keeps your home to itself.
The AR scan and saved home map are not uploaded, and there is no account to create. Speed testing, anonymous analytics, subscriptions and optional plan import are explained separately in the privacy policy.
No plug-in sensor and no LiDAR are required. On iOS 18 or later, supported iPhones without LiDAR use a walked flat map; LiDAR models can add the 3D home capture.
You get the room, the corner and the speed in plain language. "Office corner drops to 8 Mbps, too slow for video calls" is the kind of line Signl hands back.
One score for the home, one for every room in it. Signl grades each room on what it actually measured there, then rolls the rooms up into a single number. In the scan on the right the living room scores 98 at 480 Mbps and the office scores 31 at 8 Mbps, which puts the whole home at 72. Best room, worst room, and a dead zone you can finally point at.
The ones we get asked most before anybody downloads.
No. On a supported LiDAR iPhone, Signl can capture walls and furniture as a 3D home. On other supported iPhones, it uses ARKit to build a flat coverage map as you walk. Floor plan import is a separate Signl Pro option.
Visit each room and stand at the place you want to test for 12 seconds. Signl records download throughput and latency for that point, then maps and compares the rooms you measured.
iOS gates access to the connected network's SSID and BSSID behind conditions that include location authorization. Signl uses that access to identify the network being tested, not to read signal strength or RSSI. Deny it and the network name may show as unknown.
The app is free to download and there is no account to create. Signl Pro is available as auto-renewing yearly and weekly subscriptions. The App Store shows the current price for your storefront before purchase.
Your AR scan, home map, room names and saved WiFi readings stay on your iPhone. Speed-test requests, anonymous analytics and subscription status are separate technical flows; if you choose floor plan import, that image is sent for processing. The full detail is in the privacy policy.
Not yet. Signl is iPhone only today. Leave your email on the Android page and we will write to you the day it ships.
