Invisible Atlas is a privacy-first Android sensor network for exploring the invisible world around you.

Invisible Atlas is the new name for BLE Radar. It is the same app, the same network and the same node: nothing to reinstall, and no progress, credits or badges are lost.

Measure real local conditions with your phone, explore aggregated map layers, and help create useful coverage for places that have not yet been measured.

EXPLORE REAL-WORLD LAYERS
• Anonymous Bluetooth activity and WiFi network density
• Cellular reception and serving spectrum information
• Magnetic field and local anomaly context
• Atmospheric pressure and GNSS sky quality
• Deliberate artificial night-light and ambient sound-level readings
• Anonymous road-area vehicle-speed observations
• External weather and air-quality references where available

BUILD COVERAGE WITH PURPOSE
Walk, cycle or travel through areas that need more measurements. New Bluetooth and WiFi discoveries build progress toward real environmental impact. When a complete eligible unit is reached, our verified partner 1ClickImpact fulfils it as a real action (a tree planted, ocean plastic removed, or carbon captured), and its impact journey with provider evidence appears in the app.

Rewards are non-monetary and cannot be exchanged for cash, tokens or in-app currency. The user contributes anonymous coverage; the impact goes to the planet, not to a personal wallet.

Choose the cause your progress supports, including trees, food trees, ocean cleanup, carbon capture, clean-water support and animal welfare.

PRIVATE BY DESIGN
• No advertising
• No personal account required for normal use
• A pseudonymous node identity instead of a public personal profile
• Phone locations are converted into approximate map hexagons before contribution
• Nearby Bluetooth and WiFi addresses are not uploaded
• Public map readings are aggregated by area
• Atlas explanations and its optional language model run on your phone
• Sound mapping sends numerical sound levels, never audio
• Public impact profiles and named certificates are optional

KNOW WHAT A READING MEANS
Atlas explains readings in clear language, including what a value can indicate and what it cannot prove. It provides educational context, not medical, safety, navigation or weather advice.

HONEST LIMITS
Invisible Atlas is strongest where enough participating phones contribute recent readings. Phone sensors vary between devices, and some sensors may not be available. Invisible Atlas does not identify people, count crowds, guarantee traffic conditions, replace a navigation app or prove a health or safety condition.

Start with the live map, choose the layers you want to contribute, and help make the invisible world more understandable.
