Video Introduction

Device Detection Data is the missing ingredient that can turn any standard web site into a tailor-made experience for mobile phones and devices. It lets any organisation deliver an online customer experience with optimised browsing, easier transactions and faster page loading.

How does it work?

Every mobile phone is different. You'll find different screen sizes, different keyboards, different web browsers, different operating systems...

We maintain a unique device database that's been built from real handsets, manufacturer's specifications, our usage information and web site responses. Having a list of this information – we call it 51Degrees Device Data – enables a web site to identify a user's web browser and physical device type. For example, web developers can:

  • Redirect a customer to a mobile website or improve the customer experience by utilising other properties, such as screen size and input method;
  • Validate a user's device type and software version before offering downloadable content or attempting to interact;
  • Tailor the experience by using other functionality on the device, such as the type of keyboard or camera.
  • Accurately analyse mobile web usage data


Key Features:


51Degrees Device Data includes the following features:

  • High performance with 51Degrees APIs (.NET, C, Java, PHP)
