The first part - I UNDERSTAND! - shows the theorem and its converse with examples and animations.
The second part - I TEST MYSELF! - shows 4 exercises that deal with the theorem and its converse, by applying these on many cases (how to calculate of the hypotenuse of a right angled triangle, a given triangle is-it right angled, which formula to calculate the length of any right angled triangle side, how to locate the points to obtain a given right angled triangle).
Exercises are randomly generated, in other words they are different every time ; so when you run the application, the exercises you have to solve are entirely new !
Finally, the app provides you a score (% and note on 20), so that you can improve yourself and/or challenge your friends.

Simple and engaging

Good for a free app. Teaches the basic theorem and includes simple exercises for foundational understanding. You can't do any "converse" stuff unless you purchase the full $2.99 version.
Poor
Title one rocks!
Not good. I would adjust the naming of the triangle to triangle red. The refer to the sides as a,b,c. This will help clear a distinction between the name and the sides. Also, I dislike that the app uses a strange formula instead of the common/most widely used form of a^2+b^2=c^2. Your formula isn't good for classroom or review purposes. Add a lesson about what is a right triangle. This is a good link to help students start learning about this concept.
Confusing for students

Why did this app complicate the simple a sqr + b sqr = c sqr formula? Would have been a great tool if they had left well enough alone.
Not what I thought

I actually thought this was a calculating app to do the work for me. It's just a teaching tool for students.
