Should have listened to the other review, total waste. It's limited to the most insanely basic problems which means it won't help with anything since questions in homework and practice exams are all much more complex and need to be heavily adjusted for this app to even recognize. So basically, if you are looking for help this app will not help at all. Best advice for anyone taking this course is to learn how to use your calculator and refresh on euler's, trig identities, and polar. Let the calculator do all the integrations and just know how to simplify from there. This will let you focus on the actual material and efficiently solve problems since you won't have time to calculate anything by hand on a test. How could this app be improved? Add all the relevant equations and a brief theory to each section. Also, get it to recognize different Forms of equations... Expecting someone who is seeking help to do 90% of the problem for the app to find its own behind seriously defeats the purpose of the app.

I’m taking a course of DSP in college and I thought this would be helpful but not all. What a useless app, I could’ve spend 3 dollars on something I’d actually use for this app is the Wolfram Alpha, just color coated. Extremely disappointed.
