THE ROAD MAPS ITSELF

Know the road.
Keep moving.

Everyday journeys can reveal the potholes and rough stretches we all encounter. Hodos brings independent observations together on a public map—one road at a time.

Android early access. Road detection is still being validated on real devices; do not rely on Hodos as a sole safety source.

01 / THE IDEA

Just go where
you were going.

Road conditions change constantly. Hodos helps turn everyday phone observations into a clearer, shared picture—without asking you to file a report at every bump.

01

Choose to map

Opt in to automatic road mapping from the Android app. You decide when participation is on.

YOU'RE IN CONTROL
02

Travel as usual

On-device motion analysis flags possible road impacts. A single bump is not enough to establish a defect.

LOCAL ANALYSIS
03

Build confidence

Independent observations help corroborate reports. Communities can also submit repair feedback.

SHARED EVIDENCE
02 / YOUR ROADS

The places you
care about matter.

Keep track of the reports that are useful to you. Revisit the map to check a road's current public status, or look back at your own weekly journey summaries.

SAVE / 01

Keep a road close

Save public hazard reports on your phone and return to check for changes.

REVISIT / 02

See what's changed

Open a saved report to see its most recently available community status.

REMEMBER / 03

A quiet road diary

Weekly summaries stay on your device—without saving your full route.

03 / PRINCIPLES

Useful in public.
Careful in private.

01

Explore without signing in.

The public hazard map is available even when automatic mapping is turned off.

02

Keep raw motion on your phone.

Compact geolocated observations can be sent when you participate; raw sensor streams and complete routes are not uploaded.

03

Don't trust a single bump.

Multiple independent observations help corroborate possible hazards before they're shown on the shared map.

04

See the code.

Hodos is developed in the open under AGPL-3.0. Read the implementation and help make it more dependable.

04 / QUESTIONS

Good to know.

Does Hodos track my entire journey?

Motion analysis happens on your phone. Hodos submits compact geolocated road observations when mapping is enabled, not raw accelerometer data or your complete GPS route.

Can I use the map without turning on detection?

Yes. You can explore publicly confirmed road hazards without enabling automatic mapping.

When does a hazard appear on the map?

Hodos checks for repeated observations from different app installations before publishing a hazard. People can also report when a road has been repaired.

Can I save maps for offline use?

The Android app can save a nearby 20 km map area over Wi-Fi after you allow location. Saved tiles work offline; other regions and fresh hazard updates need internet.

Is Hodos available for iPhone?

Hodos is Android-first and in beta testing. iPhone support is not available yet.
