The Problem

Coverage maps
aren't reality.

Network quality changes street by street, room by room. Official carrier maps are built on tower extrapolation — not on real measurements from real people on real roads.

CellSense tells the truth.

Distributed Intelligence

Every Android device becomes a signal sensor.

CellSense runs quietly in the background — capturing RSRP, SINR, network type, and cell tower identity as you go about your day. No effort required. Passive, distributed sensing at national scale.

Infrastructure

Built as living infrastructure.

A distributed sensing pipeline designed for Nigeria's real-world conditions — including areas with intermittent connectivity.

01
Mobile Sensor
Passive RSRP/SINR readings captured continuously on-device.
02
Offline Queue
WatermelonDB buffers readings locally — no connectivity required.
03
Secure Ingestion
Readings sync via JWT-authenticated REST when back online.
04
Spatial Processing
PostGIS resolves towers, aggregates tiles, and builds heatmaps.
05
Live Intelligence
Coverage data served in real-time to app and API consumers.

The Living Map

Built from real usage.
Not simulations.

Heatmaps evolve continuously from millions of real signal readings contributed by everyday devices — updated as people move through cities, highways, and rural roads across Nigeria.

Platform API

Network intelligence,
programmable.

Carriers, regulators, logistics companies and enterprises can access real-time connectivity intelligence through a spatial analytics API — powered by crowd-sourced readings, not tower extrapolation.

Community

Every contribution
makes the map smarter.

A single contributor lights up a rural road. Many contributors illuminate entire states. As you move through Nigeria, you help build the most honest network dataset in the country.

Contributors earn points, unlock milestones, and climb the national leaderboard. Connectivity is a public good — and so is the data.
