Learn About Religions by Brainscape is a very insightful app that teaches students about major religions of the world.
The app teaches on a flash card method. Students browse the cards and select on a scale of 1 to 5 how well they know the information. The cards are then played in an order that provides more practice and focus on the information the student knows the least, so they can learn by repetition. The lessons don't go very in-depth about each religion, but rather provides a general overview and a working knowledge of each. The best thing is that the app is is free of opinionated views and only forwards factual, dry information about each religion and its beliefs.
Compatible with iPhone, iPod touch, and iPad.
