Lock Themes is a Windows Phone 8 app that keeps your lock screen wallpapers fresh by rotating images from select themes. Lock Themes provides you with over forty themes that include astronomy, nature, horoscopes, daily inspirational quotes, and travel. Lock Themes has a healthy selection of themes with new themes added weekly.
Lock Themes is laid out in simple and straight forward fashion. You have a page to turn enable/disable Lock Themes and a page listing all the themes. At the bottom of the screen you will find four command buttons; save the current lock screen to your Pictures Hub, request a theme from the developer, search the themes and clear your search results.
