Useless. You can't select anything but the frequency. And it provides impossible values for resistors. 1 ohm is not a feasible option to make a RC high pass filter. At least users must have the option to chose two things, - frequency plus either resistance or capacitance. And there are a lot of websites available for free to calculate these values extensively. No need to purchase Pro.. 😎

The main purpose of the app to find out all combinations of R and C. If I want to build a 10k RC HPF. You will get 1.6k ohm & 10nF. If you do not have 1.6k ohm on hand, you can select another combination R & C values.
We think that this approach is more practical !!!
