Device DetectionData Quality
Device detection vendors need to stay on top of the latest changes. Supported by our ISO 9001/27001 certifications, 51Degrees is the only provider that publishes weekly active and total profile metrics.
Check out the latest metrics for each component:
Browser
In the "Browser" component, we classify web browsers, WebView, popular native apps, and apps operated by our customers. Understanding the difference allows our customers to maximize revenue based on how the user is viewing the content.
We maintain 118 different properties relating to the browser. The below graph uses the IsWebApp property to populate the following categories:
- Web Browser includes Chrome, Firefox, and Safari (to name just a few)

- Unclassified (see our explanation)

Significant dates are:

For each device added to our device database, we research the vendor data sources supported by active usage data.
We update 132 properties relating to the hardware specification of a device. We have used the DeviceType property to populate the graph into the following categories:
- SmartPhone
- Tablet
- TV which also includes MediaHub
- Desktop
