HTC Sense

HTC Sense is a software suite developed by HTC, used primarily on the company's Android-based devices. HTC Sense, the successor to HTC's TouchFLO 3D, enhances Android with a revamped home screen, keyboard, widgets and HTC apps. 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.

At the Mobile World Congress 2010, HTC debuted their new updated HTC Sense UI on the HTC Desire and HTC Legend, with an upgrade available for the Hero and Magic. The new version was based upon Android 2.1 and featured interface features such as the Friend Stream widget, which aggregated Twitter, Facebook and Flickr information and Leap, which allows access to all home screens at once.

When the HTC Sensation was released, it featured HTC Sense 3.0, which added interface elements, including an updated lock screen that allows applications to be pinned directly to it for easier access. The HTC EVO 3D also features Sense 3.0.

Two versions of Sense were developed for Android 4.0. Sense 4.0, included on HTC's new devices beginning in 2012 (such as the HTC One X), was designed to provide a refreshed and more minimalist look closer to stock Android than previous versions, while integrating features provided by Android 4.0. Sense 3.6, which was distributed through updates to older HTC phones, was designed to maintain a closer resemblance to previous versions of Sense on Android 2.3.
