"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.. 😎"
