I'm currently attending school to become a certified state electrician, and I must say this app is an EXTREMELY effective study reference, and I highly recommend to any person working/studying towards an electrical apprenticeship... Or, if you just want to have fun learning about the practical basics of electricity, electronics, and the mathematics behind it. Brilliant!👍⚡💡

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.

I like this app. This is one while definitely will get the extras or the one without commercials. This comes in handy. I would have given it five stars, but really, valley App I will get five stars too would be the one that comes out and do the work for me.

Joh. A. Aug 8, 2019     

Very happy with this app.! I am an electrician in a large theme and water park. It is so nice to have virtually all of the calculations and references that I need whenever I need them, right in the palm of my hand!

Ki. T. Feb 19, 2021     

Paid for Pro version to see what it offered but it didn't have what I was looking for (pi Pico pinout). No way to request a refund as the seem to take payment outside of Google play. I'd go with something else. I'll update this if I manage to get a refund

Cla. W. Sep 29, 2021     

If you are into electronics it has all the formals and data needed to solve almost all you electronics question. I suggest you buy the PRO version. it is dirt cheap at one payment.

NIK. R. Apr 16, 2019     

it is very easy and handy application. Without going into mathematical calculation one can find the solution.

Pau. Z. Mar 3, 2020     

Very informative and easy to use. Makes learning and experimenting a prosses worth going through.

Sam. C. Nov 28, 2020     

Guys, don't be cheap. Buy the Pro version for $3 I use this even after I'm out of school. The chip stuff is nice. I especially like the common circuit calculators.

One stop shop for quick glance knowledge. Needs a tiny bit of streamlining when adding values to converters.

Luk. S. Jan 12, 2020     

Great app if you buy premium! Great info stored for general prototyping and simple calculations. Resistor color code is especially helpful.

アンソ. Dec 8, 2018     

Very cool app, saves alot of time searching online, really happy with the symbols apsect. Satsfied customer here.

Ann. B. Oct 9, 2018     

It's a good app but pls add something. Like example WHAT is the use of that or these and pls put some explanations on the tool kit every Item that might be useful though HOPE YOU READ THIS:)

Bel. T. May 26, 2020     

The ONLY app that has FIVE (5) color bands for inductors, which outstands from the crowd, BUT unfortunately it lacks GREEN code for the tolerance... so it did not helped me a lot 😔

die. f. Nov 9, 2018     

Nice app. Very useful. Upgraded to premium and it's worth for money. please add ferrite and iron core inductor calculator.

Jos. A. Oct 26, 2019     

Say you have a bunch of cables that you need to sort through and see the price of them at leading retail marketplaces like Amazon how can I do this and how can I figure out what the cords are used for at the same time I'm sure you must have this on here I just can't find it

Nom. C. Dec 20, 2019     

Resistors in series parallel doesn't go with more than 3. I chose 9 resistors what asked how many. The diagram doesn't change to suit

She. M. Nov 17, 2019     

This app has potential. However it needs some built in instructions to help beginners who are learning the subject matter.

Bri. F. Apr 2, 2019     

Great app. Would benefit from adding a transistor lookup but overall useful and easy.

Eua. R. Apr 6, 2020     

SMD resistor section doesn't work as well as capacitor codes I needed. I abandoned app and used Google to find what I needed. What a waste of money.

Jun. A. Apr 15, 2021     

I purchased the pro version and everything was good but it's still prompts if I would like to purchase the pro version. Will give 5 stars after fix

Iam. W. Jul 14, 2020     

Been an electrician for 10 years, electronics is a hobby of mine and this app has many good features, love it.

Pau. Y. Oct 3, 2020     

This app is awesome, everything you'll ever need, amazing features, what more can I say. The devs deserve a pint or 3, well done

Kev. G. Aug 17, 2021     

Paid for pro, not clear that the upgrade worked, but it looks like I can access them.

A. G. u. Jan 2, 2019     

Wonderful creation creation with this App here guys; fantastic searching methods for component values & out-lining details, how eazier can another put this ? Dont miss this !!! Tanx developers.

I've paid for pro version. It hasn't updated and refund method through play store is not working.
