Invisible Atlas's network of real phones anonymously measures Bluetooth, WiFi, cellular quality, magnetic anomaly, atmospheric pressure, artificial night light, and ambient noise by H3 area. No individual device, network name, or person is included in a reviewed buyer delivery. The evaluation map below shows the same aggregate class of data as the public Explorer.
Anonymous Bluetooth device counts per area, deduplicated, decayed toward current relevance, not a stale one-time burst from months ago.
Same anonymous-count treatment as BLE. Useful as an independent cross-check on real area activity, never a network name or router address.
A real 0-4 coverage/dead-zone rating per area, never a cell tower ID. See exactly where reception genuinely falls off.
Rotation-invariant field strength, anomaly from the geomagnetic model, and variability.
Sea-level pressure, tendency, sample count, and timestamp so stale weather is identifiable.
Deliberate lux readings with average, observed floor, sample count, and timestamp.
Approximate Leq, background, and peak levels. Numeric aggregates only, never audio.
