This app is used to calculate the RC charging circuit and RC filter. It is suitable for hobbyist or electronic engineers.

Features:
1. Calculate time constant by R and C
2. Calculate between time constant and % of charging
3. Calculate cutoff frequency of low-pass filter/ high-pass filter by resistor and capacitor values
4. To find out combinations of resistance and capacitance making a desired time constant
5. To find out combinations of resistance and capacitance making a desired cutoff frequency
6. Save all combinations in a CSV (Excel) file

Features in PRO version only:
1. No Ads
2. No limitation

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.. 😎
