Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Shankul Varada
