Built for everyday drivers
Kardyna is available to individual drivers and is not restricted to employees, municipalities, fleet operators, clients, or partner organizations.
Anyone in a supported country may download and open the app. No employment relationship, business affiliation, invitation, municipal authorization, or Kardyna account is required for public app access.
Some data-collection functions require compatible Kardyna equipment. Drivers may apply to receive or borrow equipment through the Kardyna Driver Program, subject to regional availability.
Publicly available to download and use without a Kardyna account.
Available through a separate driver-program application where inventory exists.
Available separately for municipalities, fleets, infrastructure operators, and research teams.
Volunteer without changing how you drive
Download Kardyna
Get the Kardyna iOS app from the App Store and open it on a compatible iPhone.
Review the public app
Use the public screens to understand Kardyna, permissions, supported equipment, and participation options. No account is required.
Choose how to help
You can apply for compatible Kardyna equipment if hardware-supported collection is available in your region.
Drive normally
When compatible equipment is connected and collection is enabled, Kardyna records measurements during normal journeys.
Contribute safer road information
Kardyna combines repeated measurements to highlight roughness, unusual impacts, and road segments that may need attention.
Useful before hardware approval
A normal App Store user can open the app and access public information without belonging to an organization. Hardware-supported road measurement starts only when compatible equipment is connected.
Become a Kardyna volunteer driver
Volunteer drivers help Kardyna collect broader and more frequent road-condition measurements. Participation is open to individual members of the public and is not limited to Kardyna customers or municipal employees.
Is the app free?
The Kardyna driver app is free to download, and individual drivers do not pay to create or maintain a Kardyna account because no account is required.
What about hardware?
Kardyna may provide compatible sensing equipment to selected volunteer drivers at no charge or on a temporary-loan basis where available.
Organizations
Municipalities, fleets, infrastructure operators, and research organizations may separately pay for reports, dashboards, deployments, or services.
Drive first. Never operate the app while driving.
Set up Kardyna before beginning a journey. Do not hold, adjust, or interact with your phone or Kardyna equipment while the vehicle is moving. Installation must not obstruct the driver's view or interfere with vehicle controls, airbags, or safety systems.
Privacy in plain language
Kardyna sensor files may include precise location, timestamps, device identifiers, speed, GPS quality, and motion measurements. Collection occurs when compatible equipment has recorded files and the app transfers them. The current app does not create user accounts and does not collect advertising identifiers or analytics.
Kardyna may use uploaded and derived data to operate, secure, and improve the service, including model development and aggregated road-condition outputs for customers. Users can contact Kardyna to request deletion as described in the Privacy Policy.
Clear answers for public drivers
Do I need to work for a municipality?
No. Any eligible individual can download Kardyna and use the public app. The driver hardware program is open to individual volunteers where available.
Do I need an invitation?
No invitation is required to download the app or view the public driver information.
Does Kardyna have to approve my app access?
No. Approval may apply separately to Kardyna-owned equipment, special pilots, or particular regional deployments, but not to downloading the public app.
Does the app require an account?
No. The current Kardyna Helper app does not create user accounts and does not require an account to open the public app experience.
Can I use the app without Kardyna hardware?
You can review program information, support material, privacy information, and participation options without hardware. Road-condition measurement requires compatible Kardyna equipment.
Does the app cost anything?
The public driver app is free to download. Individual drivers do not pay to create an account because no Kardyna account is required. Professional organizational services may be separately priced.
Can any organization use Kardyna?
Eligible municipalities, fleet operators, researchers, infrastructure organizations, and other organizations may contact Kardyna. The service is not restricted to a fixed list of existing clients.
