In this blog post, we will provide you with a step-by-step guide on How to calculate reference angle.

Reference angle° = angle Terminal side is in the second quadrant When the terminal side is in the second quadrant (angles from 90° to 180° or from π/2 to π), our reference angle is 180° minus

There are some problems that it can't solve yet, which is fine, especially considering it's a free app with hardly any in app purchases, if I could I'd support this app, since I can't I'll write an honest review in hopes someone will see this and give it a try. I really love the app.
