Just drive, ride, or commute as usual. Hodos quietly senses potholes, speed bumps, and rough roads from your pocket—and builds a live public map for everyone.
Effortless by design
No buttons to tap while driving. No accounts to create. Everything happens automatically on your phone.
On-device inertial sensors filter out normal vehicle vibration and isolate real road impacts—whether your phone is in your pocket, bag, or dashboard mount.
A single jolt could be a dropped phone or a curb. Hodos waits for independent passes from multiple devices before publishing a hazard on the public map.
When subsequent journeys pass smoothly over a previously rough stretch—or commuters mark it fixed—the map updates automatically.
Privacy by construction
We designed Hodos so you never have to trade your personal whereabouts for better roads.
Explore the live map or opt into road sensing immediately. No sign-ups, emails, phone numbers, or ad trackers.
Observations near the start and end of your journey are discarded on your device so home and work locations stay private.
High-frequency accelerometer streams are analyzed in memory and never uploaded. Only compact hazard candidates leave your phone.
Every line of Android sensor code and aggregation logic is public on GitHub under the MIT License for anyone to inspect.
Questions
