Ratings and reviews

Interface isn't the prettiest but it gets the job done with settings available to tweak. I just wish that the formulas were also available in pretty print so that they're easier to read. Can't comment on the paid version since I don't have it.

I have seen this app grow up and it has become extremely useful and versatile.

PLEASE CORRECT "SMD RESISTOR VALUE" OPTION.... BCZ WHEN I PUT "R100" RESISTOR VALUE IT SHOWS 100 mohm but original resistor value is 0.1 ohms.... CORRECT THAT CALCULATION.... OTHERWISE APP IS GOOD
