User reviews

Horrible

Is the worst app that I have payed in my life, I WANT BACK MY MONEY

terrible

worst 6 $ ever spent !!
u cheaters !!!!

Nice but buggy

Seems to work but there are a number of bugs and annoying things.
1. the frequency settings should stay the same or auto scale. Every time you reselect it, it goes back to the default. Very annoying.
2. Flipping through Bode to Nyquist back to Bode, the output changes to an incorrect transfer function
3. Why don't phase and magnitude appear on the same screen. This is traditional. You need to flip back and forth. Annoying.
4. Doesn't understand exponential notation. You need to use 10^n
5. Why only transfer function. Why cant it be a poles zeroes option to eliminate typing.

This app could be great if it were modified only slightly to create a more practical tool. At the present state worth $2.99 not $5.99.
