π‘ BLE Radar β Turn your Android phone into a privacy-first sensor for the world around you.
I built BLE Radar because our phones can detect far more about the physical environment than we normally get to see.
Bluetooth. Wi-Fi. Cellular signals. Navigation data. Magnetic fields. Pressure. Light. Sound. Environmental conditions.
BLE Radar brings those layers together and lets you contribute measurements to a shared geographic atlas. π
π°οΈ WHAT BLE RADAR DOES
Walk, cycle or travel with BLE Radar and help map real-world coverage.
Depending on your device and available sensors, BLE Radar can collect layers such as:
πΆ Bluetooth surroundings
π Wi-Fi environment
π‘ Cellular coverage
π§ GNSS / navigation data
π§² Magnetic measurements
π‘οΈ Pressure and environmental data
π Ambient light
π Ambient sound levels
π Movement / vehicle speed
π¦οΈ Weather and air-quality context
The goal is not just to show nearby devices.
It is to gradually build a shared, multi-layer map of the invisible environment around us.
π THE SHARED ATLAS
The public atlas currently contains:
πΊοΈ 1,346 measured H3 cells
Every contribution helps expand real-world geographic coverage.
π± SCANNING CAN ALSO CREATE REAL IMPACT
BLE Radar connects scanning activity with verified environmental and social impact through 1ClickImpact.
The verified impact ledger currently reports:
π³ 11 trees
π 2.7 kg of ocean waste removed
βοΈ 2.3 kg of carbon impact
πΎ $1 for animal welfare
Users can choose which available impact cause their scanning contributes toward.
So exploring the invisible world can also help fund something visible.
π PRIVACY FIRST
BLE Radar was designed around privacy rather than collecting personal movement histories for advertising.
The focus is environmental and radio measurements, shared geographic coverage and transparent impact accounting.
π FREE ON ANDROID
BLE Radar is available now on Google Play:
Iβm building this independently and BLE Radar is still early, so feedback from Android users is extremely valuable.
If you try it, Iβd especially love to know:
π¬ Which sensor layer do you find most interesting?
π¬ What would you like to see added to the atlas?
π¬ Does the idea of turning everyday scanning into verified environmental impact make sense to you?
π‘ Map invisible signals.
πΊοΈ Build coverage.
π± Fund verified planet impact.
Thanks for checking out BLE Radar π
