Cell Surveys: Signal Heatmap
Cellular Coverage Map & Zones
Free · Designed for iPad. Not verified for macOS.
Cell Surveys turns your iPhone into a powerful signal survey tool. Passively collect cellular signal data as you drive, walk, or commute — then view coverage heatmaps, track mileage, and identify dead zones on an interactive map.
KEY FEATURES
- Passive Signal Collection — Automatically records cellular signal strength (estimates) in the background using GPS. No manual effort required.
- Coverage Heatmaps — See color-coded signal quality overlaid on your map. Instantly spot dead zones, weak coverage areas, and strong signal corridors.
- On-Demand Surveys — Run targeted surveys for cellular, WiFi, Bluetooth, ambient noise, and light levels. Record signal data along a path with real-time charts.
- Mileage Tracking — Automatic trip detection logs your drives for IRS mileage deductions. View trip history, driving time, and estimated fuel or EV costs on the cellsurveys.com/mileage dashboard.
- Parcel-Level Detail — Tap any property on the map to see parcel boundaries, owner info, and sub-grid signal analysis for that location.
- AI Assistant — Ask questions about your survey data, coverage patterns, or signal metrics using the built-in AI chat.
- Operator Dashboard — Access detailed carrier analytics including signal-over-time charts, PCI distribution, and RSRP vs RSRQ scatter plots at cellsurveys.com/operator.
- Privacy First — All data stored on-device by default. Location and signal data are never shared without explicit consent.
Whether you're a telecom professional doing site surveys, a fleet manager tracking coverage along delivery routes, a real estate investor evaluating connectivity, or just someone who wants to find the dead zones on your commute — Cell Surveys gives you ground-truth visibility into how cellular networks actually perform.
Ratings & Reviews
Getting started is quicker.
• Signing up is one screen instead of four, with the same terms and privacy choices.
• Prefer not to allow background location? The app now works without it — surveys record while it's open, and you can turn background collection on later in Settings.
• Settings shows the correct app version again.
