To be honest, just buy it. This app is worth it. Espically for an eletroinic engineering major. Or even if you just are in a electroincs class this really helps understand and solve problems.. Its has everything you need. I used it to repair a led connected to gen transfer switch. No ads when you buy it.. Best things to do is The program you use, put it in your favorites..

The app is nice for electricians but for curious people like me (with no electric experience whatsoever) it would be nice to have explanations, definitions and conversions, like explaining which number each band represents in a resistor. Thanks.

leaves a bit to be desired. No examples. I have studied Electronics Engineering and found it not straight forward, For instance why are not current values not included with LED values. Without current values resistor value cannot be worked out. Also found that some ic's that are found with Aduino projects not included.
