Keeping speed and accessibility front-of-mind, our software engineering team rebuilt the app from the ground up – reducing the time required to download it and its contents by 70% and reducing storage by 60%, as well as making the experience of finding relevant information intuitive, fluid and, crucially, fast.

RS DesignSpark

Thanks to a programme of bespoke software development, RS Components can serve its 750,000-strong engineering community more efficiently and effectively than ever before.
