HTC has today made their lock screen app available via Google Play. The Sense 6 lock screen app is available for newer HTC devices and will allow for much easier updates, the first of which will keep users from "unintentionally triggering factory reset." The lock screen allows you to swipe right for BlinkFeed, left for Widget Home or up to previously used app.
The HTC Lock Screen joins other recent additions in Google Play including BlinkFeed and HTC Clock. Having the standalone apps in the store will allow for easier updates from HTC, keeping things in tip-top shape for your HTC device.
If you're an HTC user you can grab the updated lock screen now in Google Play.
