Avoid potholes.
The first intelligent pothole app for Android and iPhone. It automatically assesses road surfaces using sensors and protects your car from expensive repairs.
Community in numbers
"The app has already saved me twice from a broken rim in the dark. A must-have for every driver."
- Vlado, beta tester
Turn on the app in the background before your drive. We fully support Android Auto and Apple CarPlay.
Your phone automatically measures axle shocks, analyzes road bumps and saves the data to the shared database without your name – only under a device code.
An intelligent directional filter warns you in advance about known damaged sections.
If your vehicle gets damaged, generate a PDF report with one click, including 3D telemetry as bulletproof evidence.
Every month, a clear summary of your driving: how many kilometres you drove on good and on bad roads, and how much strain that put on your car.
The app silently keeps your private speed record. If you ever receive a questionable radar fine, you can generate a PDF with exact data in one click. We do not promise guaranteed legal immunity, but we give you a helpful tool and precise evidence.
On a very strong impact the app saves a record by itself – position and speed before and after the impact and the course of the impact. When the car stops, it asks you (also out loud) whether an accident happened. Add photos and create a PDF with one tap, for example for your insurer. The record stays on your phone. The app does not promise to call for help. Android version for now.
We continuously analyze pothole shocks to calculate the load on your vehicle. Thanks to a simple "green band" health indicator, you will see exactly how much strain your shock absorbers have taken since the last service or wheel alignment.
On your car screen (Android Auto and Apple CarPlay) the app guides you to your destination with voice instructions and a road-quality map along the route. If a smoother route exists, it offers it right at the start. Pick your destination on the phone or share it from Google Maps or Apple Maps.
Rides, reports and settings are backed up to your Google account, and when you install the app on a new phone it offers to restore them. You can also export the backup to a file and keep it wherever you like. We cannot see your data. Android version for now.
What we are currently working on
Warning of an accident ahead
If an accident happens on your route, the app will alert you with a tone and voice about a minute before you reach the spot – based on your speed, not a fixed distance. Only cars heading towards the accident are warned, on Android Auto too.
Frequently Asked Questions (FAQ)
Does the app track my location when I'm not driving?
No. The app only measures while you are driving a car. When you park or walk, measuring pauses automatically. You can revoke location permission at any time in your phone settings.
Who can see my data?
Trips are stored without your name, email or any account – only under a random trip number. The public map shows only road sections combined from multiple trips, never your routes. Data is stored in the EU, transfers are encrypted and we sell nothing. Details are in the Privacy Policy.
Do I have to press anything while driving?
No. The app recognises that you are driving and measures on its own in the background. If you want, you can report a road hazard with a single button.
What if I have no signal?
Nothing gets lost. Records are stored on your phone and sent once you are back online.
Which phones does it work on?
Android phones with Android 8.0 or newer, via Google Play – Android Auto is supported too (you turn it on in the app settings). iPhone as a public beta through Apple's TestFlight app. Apple CarPlay is supported too.
What is RH Red Report?
A set of reports right in the app: Road damage (a PDF with evidence when your car is damaged by a pothole), Monthly report (an overview of your trips) and Speed diary (a speed record in case of a disputed fine). They are useful supporting documents, not a guarantee of success with authorities or insurers.
Is the app free?
Yes, mapping and warnings will be free for drivers.
