HTC Sense is a software suite developed by HTC, used primarily on the company's Android-based devices. Serving as a successor to HTC's TouchFLO 3D software for Windows Mobile, Sense modifies many aspects of the Android user experience, incorporating additional features (such as an altered home screen and keyboard), additional widgets, re-designed applications, and additional HTC-developed applications. The first device with Sense, the HTC Hero, was released in 2009.
