Wanda has no use what-so-ever. It only takes up disk space and compilation time, and if loaded it also takes up precious panel space and memory. Anybody found using it should be promptly sent for a psychiatric evaluation.
For you who is normal, Wanda is a fortune cookies app written by Wanda the Fish (with some help of George). But this is not that important.
Wanda was originally created by Free Software Foundation, Inc. and adapted to Android® by .append team.
