Wolf Widget for Reddit (formerly Redditastic) is a stand-alone home screen widget.
Great as a companion to a full-fledged Reddit app you're probably already using!

Features :
* Customize each widget - change theme, color, display style, sorting
* Login to reddit to view your own reddit front page
* Multiple subreddits can be combined in a single widget
* Use the action menu on each widget to easily edit or refresh (collapsed by default, tap the '>' to expand it)
* Pick between a light, dark or transparent theme
* Scrollable and resizable

Premium features (enabled via one-time in-app purchase) :
* Extra theme - transparent theme
* Customize colors - widget title, background, post title, score-comments-name, list divider
* Colorized posts - post titles and score will get 'orange' to 'red' the higher the post score is
* Bigger thumbnails - posts with thumbnails will display a much bigger thumbnail for easier view

Please note :
* Wolf Widget doesn't provide an option to increase the number of posts displayed.
* It receives 25 posts by default. You can increase this number on Reddit.com on your (old themed) settings page under "preferences > options > display (n) links at once".
