Cell Surveys turns your Android device into a powerful signal mapping tool. Record, visualize, and analyze wireless signal strength wherever you go.

SURVEY YOUR SIGNALS
Start an on-demand survey to record cellular, WiFi, Bluetooth, sound, or light data as you move. Watch signal readings update in real time on a live chart while your path is traced on the map.

PASSIVE LIVE MAP
Leave Cell Surveys running in the background to continuously collect signal data. Your personal heatmap builds over time, showing signal quality across your neighborhood, commute, office, or anywhere you travel.

MULTIPLE SIGNAL TYPES
- Cellular: signal strength, carrier, network type, cell tower identity
- WiFi: nearby access points and signal levels
- Bluetooth: device scanning and signal strength
- Sound: ambient noise levels
- Light: ambient light sensor readings

FLEET DATA SHARING
Create or join a Fleet to pool signal data with up to 50 teammates. Share a token and PIN to invite members. Fleet heatmaps combine everyone's data so your team can map coverage across a wider area together.

COMMUNITY MAP
Enable the community layer to see aggregated, anonymous signal data contributed by all Cell Surveys users. Get a broader view of cellular coverage beyond your own recordings.

SURVEY ARCHIVES
Every survey is saved locally on your device. Browse past surveys, filter by date or signal type, replay them on the map with animated markers, and export or share them as files.

IMPORT & EXPORT
Import survey files from other devices or teammates. Export your data as CSV files or share a ZIP bundle. Save live session data to your archive at any time.

BUILT FOR PRIVACY
Your signal data stays on your device unless you choose to share it. Community contributions are anonymous and aggregated. Fleet data is only visible to fleet members. No ads. No tracking.

Ideal for network engineers, IT professionals, field technicians, researchers, or anyone curious about the wireless signals around them.
