### 1/5 — RC calculator doesn’t work

*2021-02-12, version 1.2.0*

The RC calculator does not work at all,  which was the main reason I downloaded this.  When trying to use the RC calculator the numbers are white just like the background,  so you can’t see what you’re inputting.  Once the values have been input, clicking calculate only gives a 0 result.

**Developer response:** Thank you for the feedback and I apologize for the inconvenience. I will be releasing an update soon. 

Regarding the color issue, did you happen to have any color accessibility options enabled?

And depending on the magnitudes of the inputs, sometimes the result will display "0", so some users can fix this by changing the result to a different or more appropriate magnitude (which can show a more accurate result instead of the number being rounded). Or the result might be rounded down due to insufficient decimal places (found on the settings page).

If the problems still persist, please reach out to me on here, or you can email me more details through "Report A Bug" on the settings page. 

Thank you
