Integral of vector calculator

All you simply do is take a picture and it helps you solve it, also easy to use since you can take pictures, type the problem or say it. Although you do have to get a steady, in-focus shot so it'll read it correctly, that isn't an issue at all and it really helped.

And one more addition, maybe a dark mode can be added in the application, and thanks for it being Free, but I saw alot of people complaining about the camera so kindly fix it,another thing is the premium umm.

14/10 would reccomend :p. As for me, there should have been a month free trial thing at least cos I need it only for like 10 days, best app ever. Best app for solving maths(especially calculus), highly recommended.
