51Degrees: More Than Three Times Faster!

51Degrees compares performance of our enhanced algorithm on three different commodity hardware platforms.

51Degrees is regularly evaluated against competitors DeviceAtlas and WURFL from ScientiaMobile for performance, accuracy and memory consumption. This blog post builds on the previous performance blog from 2016 with the same commodity hardware; 1) a Raspberry Pi, 2) a low-end desktop PC and 3) a high-end multi CPU server, but using an all new algorithm.

Website Optimisation for Apple devices - iPad and iPhone

51Degrees shares updated JavaScript to enable device detection for Apple devices

Author: Marketing

In 2015 we released a detailed blog on Device Detection for Apple iPhone and iPad. Since then Apple has released the iPhone 6s, 6s+, 7, 7+, 8, 8+, X, XS, XS Max and XR. Identifying Apple devices can be challenging. When putting plans in place to optimise websites for mobile devices like Apple, companies have two choices. Try and run a solution internally or simply have 51Degrees do the work for you with the added benefits of the Apple device properties we provide in our data files.

Because we endeavour to support companies and hobbyists with our unique open source solutions, we are sharing some JavaScript that will enable you to set up an internal solution if you wish. We would, however, encourage you to save yourself the time and effort and use our data files to support your strategic website optimisation decisions.
