What people like
- Great for beginners starting out
- Huge collection of useful tools
- Easy and friendly interface
- Developer listens to feedback
What they complain about
- Free version has almost no tools
- Wrong formulas for some circuits
- No support for screen readers
- Hard to find specific components
Engineer
Like the layout of the app. Not many apps follow the users own preferences and content as if they developed it. Can I make one request that would almost complete toolkit? Add a toolkit for busbars. DC and AC, copper primarily but also other materials like aluminum. This may be a personal preference but I think other Engineers using this app may find it useful as a quick estimate. Be sure to include compensation for temperature, power loss, dissipation, airflow if forced air is used, as in an enclosed environment TPM.
I would like a refund
Nothing on here that I can’t get online. Would rather look up the exact part rather than dig around on this app for something that isn’t there.
Language support
This app is good but it doesn't support multi language. I’d like to order the pro version if it supports Chinese language.
I bet it’d be useful if I could use it.
As a hobbyist who loves to work on analog audio equipment, this would be the perfect tool for me. That is, if I could use it. I’m vision-impaired, and rely on Apple’s accessibility tools to assist me in getting things done on my devices. Unfortunately, this app, as nice as it is, has zero support for accessibility. The intro screens aren’t readable, the buttons aren’t labeled, and many of them don’t even work with VoiceOver on. This saddens me, as Apple makes it fairly easy to include this support with little effort, and when a developer doesn’t take the time, I get the (possibly mistaken) impression that they just don’t care, or are taking shortcuts in their app development.
ซื้อแอพ
ซื้อแอพใน iphone แล้วทำไมใน ipad ยังไม่เป็นรุ่นโปร?
Keep the updates coming
I used this app for an opamps class. It was useful. Please keep the formulas and stuff coming. It didn’t cover everything. Also, thank you for not collecting and selling our data.
The RenBuilder
There are no anolog triac based power control components
Can’t zoom, hard to see…
Can’t zoom, hard to see, but great app other than that!
Rubbish
Absolutely nothing on here about kirchhvos laws. I was looking to buid a circuit and add resistors and then play and see the values. But no its all just rubbish
Spanish
Te doy 5 estrellas si agregan idioma español
The old Russian lady
Adobe fresh American would love something like this.
Don’t buy this app
This app doesn’t have all the documents available in it the pdf are empty and most of them and the apple also refuses to refund.
Just an recommendation
A great app! But one small recommendation: Can you add an circuit maker? It’s fine if you won’t add it! But I would like to make circuits and test them
Not many options, unless you spend $7.99
Being a developer myself, I don’t see this app as a good value. This should include a few more options before you have to pay. It should at least be somewhat useful. The 30% / 70% should be implemented. I hope the developer takes my comment and updates the app. I feel many more users will download after making some small changes.
Comprehensive but some clunky bits
The resistor code “manual configutator” requires me to drag column of colors to choose each band. If this pane could have a full screen mode, it would allow me to tap the color of each band more quickly. In the section on single board computers, the board pictures are very low res, fine for just getting a general idea but not very detailed.
ExcellentToolkit
Extremely useful set of tools, excellent content, great reference, and not just for the DIYer, but for those actively involved in the electronics field. Highly recommend you add this to your toolkit of electronics applications.
Too good to be true 👎🏿
Says free app but once inside be prepared to pay for what you probably thought was gonna be free 👎🏿
Please add schematic symbol descriptions
Very nice app.
All the useful tools are locked for pro.
Not impressed. Everything useful is an in app purchase. The free stuff barely covers the basics you can do in your head.
esp32 please
Can we please have esp32 microcontroller and their various experimental/development boards added pls. These are used in numerous projects and are not new at all.
Move over CDC handbook
This is a phenomenal app. Just the data sheets alone are worthy, but the breadth of stuff here is amazing.
Fraud
Upgraded to pro lifetime but still getting blocked
Kirchhoff’s laws?
I love it. It’s a great tool for the money. I would like to see node analysis and Kirchhoff’s laws added.
App is dishonest
App bribes users into leaving 5-star ratings by promising to unlock 7 more tools. Reviews can't be trusted.
Dumb
Dumb
Thank you
This is an amazing app that comes in handy. Blown away with it! My new goto
No stars earned for poor communication skills presented at this time
Improve hospitality less friction in communication.
Nice
This is a great app and has a lot of great features! Issues with voltage divider (loaded) . Looks like Rload and Vin are swapped.
Missing some content
The GPIO section diagrams all look the same regardless of which operation mode you’re looking at. Microcontrollers should really have an STM32 section. Other than that a useful tool. Would be helpful to have frequency as an option for spectrum instead of nanometers.
Imagine having every calculator you ever needed
This app has everything you need on a day to day basis for electronics work … it’s incredible! Nuff said … get it you’ll be glad!
Garbage
Another locked behind paywall software that wont help a novice build their own circuit. Instead its all comprehensive to what these narcissistic electrical engineers think
Great app!!
Thomas, please can you allow page zooming in especially for connector definitions?
Wrong Formulas - Can’t trust the app then?
Just bought the pro version for $7,00 or 30 BRL aprox. And the first thing that I check is the Q factor formula for RLC series circuits... and it’s just wrong! q = {1/R}*sqrt(L/C) not R*sqrt(C/L). The second formula is for RLC parallel circuits and not series, this makes me think that I can’t trust the rest of the features of the app. 🤦🏻♂️ If it was at least free I would not complain but I didn’t paid 30 BRL for this. It would be easier to just go ahead and save the Wikipedia page of the things I want at the Wikipedia app then? 🤷🏻♂️
Very useful app!
I wish I had this available when I studied electronics engineering ages ago. Now I am getting back into electronics as a hobbyist and this app is making the journey so much easier. Please keep adding content to it!!
Worst ever
I would say it is not the best but not the worst. I say this because it says upgrade to premium and you will get this and that. But a plus is that they say spend 7.99 some dollars. Like why though it is literally useless.😬🤮🤢🥱😿😾
Good app
Thank you for making this app. Very useful and easy to use
Schön gemacht aber...
Ich habe mir das Tool gerade geleistet, weil ich mir eine Vergleichslistenrecherche per Papier sparen wollte. Im Netz findet man zwar auch brauchbare Listen aber ich dachte, mit dieser App das alles erschlagen zu können. Ich bin aber schon bei der Suche eines simplen Triacs gescheitert. Nicht nur, dass der Datenbestand insgesamt sehr gering ist, es gibt noch nicht einmal eine simple Suchfunktion, mit der ich mir eine Suche deutlich erleichtern könnte. Da ist noch ne Menge Luft nach oben. Schade
A Must-Have for Electronics Enthusiasts
I’ve been using the EE Toolkit app and it’s nothing short of amazing. As someone deeply interested in electronics, this app has everything I could ever need. It’s like having a comprehensive electronics toolbox right in my pocket. The app is incredibly user-friendly and designed with both iPhone and iPad users in mind. It offers more than 160 electronic applications, a multi-functional keyboard, a large selection of color code tools, and even a full-featured frequency generator. The real-time circuit simulations of example circuits are a game-changer. What sets this app apart is its constant and powerful improvements. It’s clear that the developer, an electronics enthusiast with a master’s degree in Electronics Engineering, is committed to providing the best possible experience for users. The Pro version is also worth considering for the additional features it offers. In conclusion, whether you’re an engineer, student, hobbyist, or just someone interested in Electronics Engineering, the EE Toolkit app is a valuable resource. It’s free to download with an option to upgrade, and in my opinion, it’s worth every penny. Highly recommended!
Not many functions in free version
The pro version looks good but the free version has very little available.
Nice interface !!
lot of compenant and nice interface !
Alright
It's pretty good
Found this a couple weeks after I really needed it
Free version is great for those starting in electronics/electrical Paid version I haven’t tried yet but from what I’ve seen I’d say it’s worth the roughly $10 if you need some of those options
Didn’t get the paid version
I didn’t get the paid version and all the function are locked. Thanks for nothing.
Handy
Helps loads with EEE degree
