SignalScout is a personal cellular signal mapper. You walk your house, porch, and yard, log the signal you actually get at each spot, and build your own coverage map — the one your carrier's marketing map will never show you.
Each reading takes about ten seconds: bars, radio type such as 5G NR or 4G LTE, carrier, and a note chip like porch, indoors, or basement, all pinned to the location. Over days the map fills in, and the pattern becomes obvious — one bar in the kitchen, five on the porch.
SignalScout is honest about what an iPhone can know. It does not claim to show cell tower locations or your live serving cell; every number on screen is a reading you took yourself, at a real place and time. That is exactly what makes the log useful when you pick a carrier or complain about coverage.
Your logged readings appear as pins on a map, strong and weak side by side, so kitchen-versus-porch contrast is visible at a glance.
Pick the bars, tap the radio type, add a note chip like porch or basement, and the reading is saved to that spot.
Compare carriers from your own readings with per-carrier scores, so you can see who actually wins at your address.
A compass arrow with bearing and distance points you back to your strongest recorded spot.
A full log of your readings with radio tech, notes, and dates — see where 5G really reaches and where it quietly drops to LTE.
Export your readings as a clean table you can show a carrier when you dispute coverage or shop for a plan.
Move through the house, porch, and yard with your phone — the places where calls drop are the places to log.
Record bars, radio type, and a note in about ten seconds. Each reading is pinned to where you stood.
Strong and weak pins build your personal coverage picture — and the carrier showdown scores who wins at your address.
Follow the aim compass to your best spot, or export the log as proof when talking to your carrier.
Walk each room and compare readings instead of guessing from one glance at the status bar. SignalScout makes this systematic: log a ten-second reading in each room and on the porch, and the map shows your strongest and weakest spots side by side. The aim compass can then point you back to the best one.
Walls, metal, insulation, and low-emissivity windows absorb cellular radio waves, so signal often collapses indoors while the yard is fine. The pattern is specific to your building and carrier. Mapping your own readings room by room shows exactly where the drop happens, which helps you place a router, a booster, or just your favorite chair.
You can watch the status bar, but bars change with location faster than you can remember them. SignalScout turns that into data: you log bars, radio type, and carrier at each spot, pinned to GPS. Over a few days you get a personal signal map instead of a vague impression.
No public iOS API exposes dBm, cell IDs, or your live serving tower, and apps that claim otherwise are estimating. SignalScout works with what an iPhone truthfully knows — bars, radio technology, and carrier — and is upfront that every value is your own reading, not lab telemetry. For real decisions, consistent honest readings beat fake precision.
The only reliable answer comes from readings taken at your address — coverage maps are averaged and optimistic. SignalScout's carrier showdown scores each carrier from the samples you logged, with sample counts shown, so you can see who actually wins on your porch before you commit to a plan.
Your phone can show a 5G badge outside and quietly fall back to LTE indoors. Log readings in each room with SignalScout and the history shows the radio type per spot — 5G NR here, 4G LTE there — so you know where 5G really reaches rather than where the coverage map paints it.
Start from your strongest outdoor reading: that is where the donor antenna will do its best work. Log readings around the house and yard, then use SignalScout's aim compass, which gives a bearing and distance back to your strongest recorded spot, as a practical guide while you position hardware.
A dated log of readings at your address is far more persuasive than "it drops all the time." SignalScout exports your full signal history as CSV — spots, bars, radio type, notes, dates — a tidy table you can attach to a complaint or bring to a store when negotiating.
No. iOS exposes no tower locations or cell IDs to apps, and SignalScout will not draw pins it cannot verify. Instead it maps something more useful and fully truthful: the signal you personally measured at each spot. Every pin on the map is a reading you took.
They are modeled predictions averaged over large areas, so they routinely show solid coverage at addresses with unusable indoor signal. They cannot see your walls. A personal signal log made at your actual address is the ground truth those maps are missing, and it is exactly what SignalScout builds.
Yes. SignalScout is built for exactly this: walk the property, log readings at the barn, the back field, the basement, and the map shows dead zones as weak pins among strong ones. Notes like porch or indoors keep the log readable months later.
5G NR is the newer radio standard with higher potential speeds; 4G LTE is the previous generation that still carries much real-world traffic. Phones switch between them constantly based on signal. SignalScout tags every reading with the radio type, so you can see which network you actually get in each place, not just what the status bar flashed once.
Map your dead zones and find your five-bar spot.
