Download Electronics Tools: ElectroCalc APK Free to carry a complete electronic circuit calculations tool in your pocket. This electronics calculator app helps students of power electronics, electronics professionals, and DIYers solve simple and complex electronic circuits, from resistor color codes to antenna gain.
The application contains 7 sections: Calculators, Circuit images, Pinouts, Resources, Converters, Formulas, and Dictionary. Each section covers one part of circuit work, so you can move from a calculation to a pinout diagram or a reference table without leaving the app.
The calculators section is the core of the app. It walks through the numbers behind real circuits, whether you are sizing a resistor, checking a filter, or working out how long a battery will last.
– Resistor and Inductor Codes: Work out resistor color codes for 3, 4, 5 and 6 bands, inductor color codes for 4 and 5 bands, and SMD resistor codes.
– Ohm’s Law and Dividers: Solve circuits with the Ohm’s law calculator, the voltage divider calculator, and the current divider calculator.
– Series and Parallel Networks: Calculate series and parallel resistors, capacitors, and inductors, plus series and parallel impedance of a circuit.
– Capacitors and Filters: Find capacitor marking, the voltage across a capacitor, discharge time, and charging and discharging behavior, along with low pass, high pass, band pass, and band stop filters.
– Transistors and Amplifiers: Work with a BJT as a differential amplifier, a BJT as a switch, collector feedback bias, and BJT transistor bias, plus inverting, non inverting, differentiator, integrator, differential, voltage adder, and instrumentation amplifiers.
– Regulators, Timers, and Antennas: Use the LM 317 and LM 7805 voltage regulator calculators, the NE 555 timer in astable and monostable modes, and conical horn and parabolic antenna gain with down tilt angle.
– More Circuit Tools: Calculate LED resistors, stepper motors, air core and coax cable inductance, Zener diodes, tunnel diode oscillators, PCB trace width, battery life, and Wheatstone, Anderson, Wien bridge oscillator, Maxwell, and Hay bridges.
Every calculation stays focused on the circuit in front of you, with the numbers and the method close at hand.
Beyond the calculators, the app gathers the reference material that surrounds circuit work: diagrams, connector pinouts, conversion tables, and a dictionary of terms.
– Circuit Images: Study a simplified graphical representation of an electronic circuit, where a pictorial diagram uses simple images of components and a schematic diagram shows components as simplified standard symbols.
– Pinouts: Find pinouts for parallel and serial port connectors, DVI, SCART, DisplayPort, Type A HDMI and Type B and D HDMI connectors, the NE 555 timer IC, LCD screens, VGA, SD and SIM cards, fiber EIA 598 A color code, Swisscom color, PDMI, and SATA power connectors.
– Resources: Use quick reference tables for AWG conversion, capacitor marking code, dBm to dB and watt, radio frequency, resistivity of materials, SI derived units and prefixes, SMD resistor code, symbols and abbreviations, and the USB power standard.
– Converters: Convert between units for current, voltage, resistance, temperature, data, energy, angle, power, pressure, volume, work, capacitance, and resistivity.
– Formulas and Dictionary: Look up formulas for each calculation and learn hundreds of electronics engineering terms in the built-in dictionary, written to be easy to understand.
With these sections together, the app works as both a calculator and a reference shelf for electronics work.
Whether you are studying power electronics, working as an electronics professional, or building circuits as a DIY hobbyist, this electronics calculator app puts the tools for electronic circuit calculation in one place. Androidru.com Android App Store is the best and safest APK downloader in 2027, and it is where you can get the Electronics Tools: ElectroCalc APK for Android.

Excellent app!
very complicated
Very interesting and straight forward.
very nice for my ambition
Installed, pressed one button=advert watched advert pressed a button = advert uninstalled.
great resource!
Thanks for your help.
saving the unforseen circumstances cut costs
useful
listen your adverts and app put in ..... no one need it
amazing
Absolutely a great tool it the workshop at home
Absolutely unusable with constant ads at every keystroke. Forget it. Pity you can't give 0 stars!
more perfect than expected

I wish more features were free
Heavily infected with Temu spam.
good nice safety
incredible

the app is so wonderful 👍
great resource but when I open a menu, the top entry sits above the header and under my status bar making it inaccessible
Absolutely fine this app
usefull
تطبيق ممتاز احتاج لي شراء النسخة المدفوعة
Super clear and potable.
very good learning electronic
sangat berguna utk yg baru berjinak dalam bidang electronik. memang nk ingat semua susah. nasib baik fitur senang cari. terbaik cuma byk yg penting kena rwgister PRO dulu
okay
v.good !
thus has been the most useful tool for me on my adventure to learning microcomponents...I recommend it to everyone
جميل وسهل
Es un proyecto espectacular en mi caso que no soy muy versado en estos temas pero es de gran ayuda para mí .les agradezco en pensar en personas como yo que tenemos muchas limitaciones en estos temas.. GRACIAS 😊 saludos desde Puerto Rico
good
Good 👍 app
i like this app because additional to help electronics technician for troubleshooting 😊😊
useful
nice
pure W. This app teached the basic components teached me how to take out the formula. Even though it takes money, you can still use The free one. My one request to devs are to take out the formula of other components freely then this will be the basic foundation for early age like me.
great idea
I recommend this app to everyone. Just download it a discover new learning skills.
Impressive and useful, and Pro mode is the best I assume... thanks
This app contains so much information and is so easy to use, it's very useful if interested in electronics for making circuits or repairs too.
This app is very helpful for electronics components for calculates of frequencies etc.
it's really very useful, just try it, and see for yourself,it will make your design life easier
Why in heavens sweet name must every murha fakin app have 1000 ads bfore anything gets done or started.. all this nonsense with ads will force us to use other platforms wich dont support your stupid adds that has NOTHING to do with what u want..im so over this ahit
Very informative, nice layout and easy to use.
Good and useful. Thanks to the person who has been prepared and created this app God bless you and your family.
Many items locked away behind a paywall. Instant uninstall!
Heck no. I couldn't even see the first page before a full screen ad popped up. I've never uninstalled an app so fast.
what a waste of time. the resistors calculator doesn't have enough bands. i can't find anywhere to add another
Once I paid up the app worked fine so I'm using it for my everyday electronics go-to instead of reaching for my Horowitz & Hill "bible" Thanks.
Completely unusable with the ads that take over the screen and don't close. Even after waiting for the timer to expire, the ads don't close no matter what. Have to force close the app to get control of the phone back. After every button press it'll give a slider ad. Unfortunately, after maybe every 3 attempts to try the sections it gives that full screen ad. I understand needing ads, but if their ad provider selection ruins their app, then it ruins their app! Uninstalled unfortunately.
not very easy to use, only stack functions but not built from the people actually use it
Ads, ads, disruptive ads. Uninstall
this app work like a teacher and I really gaining more knowledge about electric and My personal opinion that any one never gave you as deeply. Thankx developers.
what an absolute crock of shyte. can't even get into the app because of stupid adverts. installed 0736 unistalled 0739. utter waste of time.
really wish I had more money to buy the full version....
tons of ads, screen formatting is incorrect, in many ways unusable
Ads overlay app, how do you convert watts to amps? It is not easy to navigate during the ads and whether it is worth buying. Previous reviews state there has been very little update activity. You should probably avoid purchasing.
it could be a useful ap but it's so loaded with ads and click bait. Don't bother downloading.
nothing but ads cant use app having to open and close useless uninstall
Paid for ElectoCalc lifetime. The app is totally unusable and Im out money. (-)☆☆☆☆☆
I purchased the pro. Great app though there hasn't been any update for ages therefore I'm wondering if this is still being maintained.
ads don't have any thing to close them. had tamu on my screen for 10 mins before I closed the app. the ads have no way to remove them to access the app. am now going to uninstall and find one with less ads
its not so useful... and too much add..
Unusable because of ads
I LIKE IT, It's very helpful to the learner,
Very usefull for beginner of electronics
Not very helpful when you have the useful stuff to me anyway locked
Is there a paid version so I can get rid of these damn intrusive ads?
There are way too many ads every time the app is loading
Too many ads Start the app? 30s ads Click anything? Pop up ad It lasted 30 seconds on my phone
Overall it's good and handy for beginners such as myself. But I think if there weren't any ads( that just pops out of nowhere) it's disturbing
It's very good app which is simplifing electrical and electronic systems.
Ads just popping up
Another BUG in the Ohm's Law calculator - if you calculating Current(A), the symbol shows Ohms & similarly when switching to calculate any of the other values, the unit of measurement shown next to the entered value is always for another unit of measurement than the unit it should be showing... Not sure how clear my explanation is, but if you use the Ohm's Law calculator, You'll see what I mean... ;)
Too much adds. Unable to use due to frequent adds.
Very bad ads come again and again
It's just an app for ads.
Absurd amount of LONG ads
Too many advertisements n most contents need paid version
No use, you have to pay, All features need payment!!!!
Very bad apps. Only showing ads. You cannot use
Very easy to use and visual content is key to learning. Very informative.
I understand that free apps will have ads, but as soon as I open it, there is a half page add, and the first calculator I opened was a video ad. That's ridiculous.
too many ads ... there are much better apps available.
Very useful for a technician like myself
Strange that I can't see the review score of the app. Unfortunately, I can't give zero stars to the app. Toxic, aggressive adds, uninstall immideatly after installation. It would be nice if Google appstore implemented a quick extended stars review with a few criteria: ADDS LEVEL, application value, user experience, etc. Then users will not spend time installing such aps. Also it would be nice to see the app origing country. This application is from Pakistan. Regards.
Riddled with ads and no option to remove ads.
Great app.just trying to make a speed controller.
So far, it's looking like a keeper to help get the drone flying again!!!!
Too many ads pop up constantly. You can't even solve your finish line equation without ads popping up and get in the way.
Ridiculous amount of ads.
Parallel resistor Calc is wrong. Temp converter isn't even close and that's all I've looked at and probably all I'll look at at
So far it is great app and easy to use.
Love it, been using it for a few years now. Great app! Wish i was smart enough and educated enough to fully use it, lol.
A very convienient app for fast on the fly formulas and calculations!
Immediate 30 second unskippable ads. Thanks, but no.
Trace width calculation seems wrong. Too many adds.
Good for the knowledge about the electrical for the beginner learning
I do a lot of electrical calculations and I find this application indispensable.
Was good at first, now uncloseable pop up ads make it completely useless
Maybe a good app but I do not like the advertising in the app. Also been permanently bothered with pop up messages about the pro version. Only one star. Useless for me and waste of my time. Get it fixed and I maybe come back
There are ads and there are get totally in the way adds. Hard to evaluate. But real telling is the things that should be here, and are not!
Loud full page overbearing gambling ads right from opening app. Had to close app to shut off ad. Uninstalled,not interested.
Awesome app ,quite useful because being human means we can't recall everything all the time therefore the app is extremely handy. Definitely not for a novice though
Great app easy to use . Nice layout
Great App. Bought the Pro version and worth every penny. Thanks....
Bug found in ohms law calculator. Ohms, only has options from amp/current table. Current, only has options from ohms/resistance table.
It's really a good app, everything I've ever wanted to know, now I know am so grateful and thanks to the increase in technology
Great app. Since i downloaded this app its the only one i need. Uninstalled 5 others that didnt do the job of this one.
Most clearly knowing the component parts
Scam app. They must clearly mention the in-app purchases. Useless
It's a good app for mature electronics engineers and it is easy to use because it has physical formulas
Most accurate and efficient.
I am engineer of mechatronics master, and i have a long experience on industrial electro instalations especially for cabinets for command and control machines
Parallel resistance calc not working with more than 2 resistors. For instance (3) 100 ohm resistors in parallel should equal 33.33 ohms. With the app it equals 3333.33 ohms. Formula is wrong. If that basic calc is wrong what else is wrong.
Most powerful app for electronic engineers and students
