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.
Just enable the Lock Themes, swipe over to the themes listing, and choose the theme of your choice. Lock screen wallpapers are rotated throughout the day but you lack the ability to set the rotation schedule.
All in all, Lock Themes is a nice app to keep your Windows Phone lock screen fresh throughout the day. There is a free trial version available for Lock Themes that has a limited selection of themes. The full version is currently running $.99 and you can find it all here at the Windows Phone Store.
