Dealing with Multiple UI Form Factors? Revolutionize the process with FireUI

RAD Studio 10.3.1 Rio and the FireUI Multi-Device Designer delivers the only true single source solution for natively compiled applications. Most vendors who support native cross-platform development require separate user interfaces to be written on each platform.

Build a common UI that works across multiple form factors of mobile phones, tablets, and desktop systems. Most mobile development solutions do not support the creation of PC apps for Windows and OS X.

RAD Studio continues to enhance the process of building great apps with FireUI! The all new Multi-Device Preview provides a design time side-by-side view comparing your apps UI over different form factors on a given platform – all in one window!
