Self-Calibrating Sensing
Continuous Median Absolute Deviation (MAD) envelope tracking automatically adapts to heavy bus leaf springs, passenger cars, or scooters.
NO MANUAL CONFIGURATIONGLOBAL ROAD SENSING
Know the road.
Anywhere in the world.
Hodos turns everyday phone observations into high-precision road condition maps. No manual logging, no phone-buzzing distraction, and zero privacy compromise. Just drive, ride, or cycle—the road maps itself.
Production release 1.2.0. Clean, autonomous road detection on any paved or unpaved route worldwide.

01 / HOW IT WORKSPure motion.
Pure motion.
Zero distraction.
Road conditions evolve every day after rains, frost, and heavy vehicle traffic. Hodos extracts pavement intelligence quietly in the background without needing you to touch your phone.
Corroborated Impact Filter
A single bump never publishes a defect. Hodos requires multiple independent passes and distinct devices before a hazard is confirmed.

Raw impact clusters are converted into Uber H3 hexagonal spatial bins and International Roughness Index (IRI) data for city planners.

05 / QUESTIONS
Good to know.
How does Hodos detect road hazards automatically?
Hodos runs a lightweight background service that evaluates continuous accelerometer and gyroscope data with Median Absolute Deviation (MAD) envelope tracking. When you pass over a pothole or severe bump, the sudden impulse is recorded and verified without manual input.
How does Hodos prevent false alarms from vehicle vibrations?
Continuous noise-floor tracking dynamically adjusts sensitivity. Continuous chassis vibration from buses, trucks, or motorcycles automatically raises the baseline filter so only true road surface shocks trigger an observation.
Who has access to the road condition data?
Everyone. The road defect map and aggregated condition layers are public and open under the MIT License. Municipal road authorities, civil engineers, and citizens can freely view live hazards or download GeoJSON and GPX files for GIS mapping and repair planning.
Does Hodos vibrate my phone when hitting a bump?
No. Haptic vibration is disabled so your phone stays quiet in your pocket or vehicle mount without distracting you.
