It is worth a try for demo use, and it doesn't look like a bad way to learn about resistors, capacitors and inductors. The device library looks very limited and simplified, and I couldn't see any obvious way to add components. For the price, it is not a bad learning program.
In the longer term, you are probably going to go further with LTSpice (
https://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html) , or one of the open source Spice applications like QUCS (

SPICE is the component simulation method developed back in the 1960's and it has basically been the standard since.
