Wallpaper Changer

This app allows you to quickly change your wallpaper with one single click on a widget!
Additionally, you can enable a timer to automatically change your wallpaper on a predefined time or when entering a specific location.
This app is optimized for battery life & performence, so it might take some seconds to actually change the wallpaper after a click on the widget!
Features:
• Easily add images or whole folders
• Change wallpaper with a timer, on each lockscreen unlock, through a customizable widget, based on your location or at specific times on specific days
• Widgets: change to next wallpaper in rotation list, select the wallpaper you want to see or change the album* with one click
• Ordered rotation or random list
• Very low battery consumption
• No ads
• Muzei integration
* Organizing your images in different albums requires purchasing the "albums feature" through an in-app payment (~ 0.99 EUR / USD)
