Ratings and reviews

It has great potential. Needs to have parallel resonance added. Need to work on variable designations in apps. Some are so small it cannot be seen. Many of variables do not match with what is being computed. Each app should have an explanation of what is going on and how to use the app. This would be an option user could access if they wanted to.

Not very good. it does not even calculate sometimes. Like for the inductive cct. Also the ads are invasive, pop up even when I'm exiting. Also, the screen pop up for enter text or number is not configured properly, it appears even when I touch outside the number field, so it is hard to scroll down to hit calcuate.

Not very useful. A lot of the calculators are completely blocked by ads. You can't even close the ad to try the calculator. You can't even try before you buy. Don't bother with this one there's plenty of others that are much better and allow you to try them first.

What’s new

Added Radio Frequency and electronics circuit design calculations such as: Buck/Boost converter circuit design, heatsink calculation, LC matching network, return loss/VSWR calculations.
