Cell Surveys

About

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, and Bluetooth. Record signal data along a path with real-time charts. - Mileage Tracking — Automatic trip detection logs your drives for IRS mileage deductions. Review trips on a calendar, see each drive on the map, mark trips work or personal, and check driving time and estimated fuel or EV costs. Export a CSV whenever you need it, all in the app. - 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 in the AI chat, using your own Anthropic or OpenAI API key. - Parcel Coverage Dashboard — Lock onto a property and open its dashboard: a 5-meter signal grid on the map and in 3D by floor or elevation, a coverage quality breakdown, carriers and network types seen, and property details. Filter by day, week, month or a custom range, and watch readings from your other devices on the same account arrive live. - Privacy First — No ads, no trackers, and your data is never sold. Readings sync to your account to build your maps and mileage; the public crowd coverage map shows only average signal per area, never your account or trips. 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.
