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, additional widgets, re-designed applications, and additional HTC-developed applications. The first device with Sense, the HTC Hero, was released in 2009. The HD2 running Windows Mobile 6.5, released later the same year, included Sense. Following the release of the Hero, all future Android devices by HTC were shipped with Sense, except for the Nexus One, the Desire Z, the HTC First, the Google Pixel and Pixel 2, and the Nexus 9 which used a stock version of Android. Also some HTC smartphones that are using MediaTek processors come without HTC Sense.
