Trig! app for iPhone and iPad

Trig! is a trigonometry mastery app for the iPad. It is designed to help students learn such trigonometry concepts as using the Sine, Cosine , and Tangent ratios to find missing sides or angles in right angled triangles. Students also learn to use the Law of Sines and Law of Cosines to find missing sides or angles in non-right angle triangles.
The app allows students to learn and practice trigonometry with instant feedback.
Student results are saved to an online database, as well as on the iPad. Students can work offline.
Video explanations and instruction are available for each topic.
