User reviews

At last!!!!

I have been looking for a program to check my calculations easily and I have finally found one that does exactly what I want. There are lots of others on the market but you won't be disappointed with this as it's not overly complicated (if U don't want it to be) and does exactly what it says on the tin!!

Great update

New user interface look great.

Doesn’t seem to work?

I don’t know what I’m doing wrong but it seems the components won’t rotate… I can’t use it. Seems it could be a bit more intuitive.

Essential for EE students

This app is a flippin lifesaver-almost feels like cheating to use it! It’s been a really great tool for doublechecking my circuit analysis calculations for class assignments

Add element boxes?

Can you also add the possibility for resistors to be read in voltage and ability to converting to resistance? Add batteries? Some circuits the resistors have voltages read as them we must find Vfb in the circuit aka high and low sides.

Also I get it’s a calculator but I just built a circuit and didn’t get any option for calculation.
