### 4/5 — Language support

*2025-12-24, version 15.0.0*

This app is good but it doesn't support multi language. I’d like to order the pro version if it supports Chinese language.

### 5/5 — ExcellentToolkit

*2025-02-28, version 13.7.0*

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.

### 5/5 — Why.

*2025-02-26, version 13.6.0*

Don’t even bother. In the App Store, they made it look like an app with not just tools, but also simulation. There is no simulation, which is the only thing I’m looking for. And the tools aren’t any better than something you could find on the internet, and to top that off, they decided to lock a bunch of them anyway. I have no idea what the hell is wrong with the people leaving 5 stars, but don’t trust them. Whatever you do. Do not trust the 5 star reviews. They all lie. I want to find something good about this app, but really I just can’t. So, please, don’t even bother downloading it. Just look for something else. Pretty much anything is better than this, even something online. Seriously, anyone leaving 5 stars willingly is either someone who was bribed or someone who works for the people who made this, and there is no way that anybody can change my mind on that. Thank you to anyone who took the time to read this whole thing, except for the developers. If you’re reading this, good job making an app that is somehow worse than social media. I didn’t think that was possible, but you pulled it off.

### 2/5 — I bet it’d be useful if I could use it.

*2025-02-17, version 13.6.0*

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.

### 5/5 — Versatile and useful!

*2025-01-15, version 13.6.0*

I'm likely to buy the pro version at some point.

### 5/5 — Move over CDC handbook

*2024-10-13, version 13.5.0*

This is a phenomenal app.  Just the data sheets alone are worthy, but the breadth of stuff here is amazing.

### 5/5 — Thank you

*2024-10-01, version 13.5.0*

This is an amazing app that comes in handy. Blown away with it! My new goto

### 5/5 — Imagine having every calculator you ever needed

*2024-09-12, version 13.5.0*

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!

### 5/5 — Beste App, die ich je hatte

*2024-07-31*

Das ist die beste App, die ich je benutzt habe, für all das wissen, was hier kostenlos vermittelt wird, mit interaktiven Schaltungen kann man nur dankbar sein. Die 8€ für die Vokllversion sind mehr als zu günstig, für das extra Material. Allein das 1. 1/4, welches hier umsonst kommt ist viel mehr Wert. Die App ist eine Super Einstigsmöglichkeit für Anfäger, die z.B. mal mit dem 555-Timer herumspielen wollen, aber auch perfekt für Profis geeignet.

### 5/5 — Very useful app!

*2024-07-21, version 13.5.0*

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!!

### 5/5 — Exzellent. Punkt.

*2024-06-30*

Herausragend gute App mit großem und stetig wachsendem Funktionsumfang. Außerdem sich optisch ein Hingucker, der wirklich Spaß macht. Meiner Meinung nach ein absolutes Muss für jeden/jede, der/die sich mit Elektronik und Elektrotechnik beschäftigt.

### 4/5 — 希望能出中文版

*2024-06-30*

英文水平一般，看不太懂，一样出一个中文版的

### 5/5 — A Must-Have for Electronics Enthusiasts

*2024-06-27, version 13.4.0*

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!

### 5/5 — Found this a couple weeks after I really needed it

*2024-04-27, version 13.4.0*

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

### 5/5 — To EE toolkit

*2024-04-06, version 13.4.0*

Dejar EE toolkit I like this App because it is a engineer App Evidence: When I want to be when I grow up I wanna be a enginner 

From The best Enginner Jaziel

### 5/5 — Good job

*2024-04-01, version 13.4.0*

I hope you add more feature about automotive

### 5/5 — A+ MASSIVE UTILITY

*2024-03-26, version 13.4.0*

Wonderful app that replaces many other apps I had free versions of. Worth the money for Pro. I build electronics like violet ray and rife machine, and this app helps so much. A frequency detector, generator, and formula calculators. #hypersanity approves. THANK YOU TOM!

## Most critical reviews (10 lowest-rated)

### 1/5 — I would like a refund

*2026-02-09, version 15.0.0*

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.

### 1/5 — 한국어패치좀

*2025-03-19*

한국어패치좀해줘요 영어 싫어요 영어때뭉레 토할거같아요 🤮
i hate english so you make korean toolkit

### 1/5 — The RenBuilder

*2024-04-03, version 13.4.0*

There are no anolog triac based power control components

### 1/5 — Don’t buy this app

*2023-02-07, version 12.7.0*

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.

### 1/5 — Too good to be true 👎🏿

*2022-07-30, version 12.6.0*

Says free app but once inside be prepared to pay for what you probably thought was gonna be free 👎🏿

### 1/5 — Fraud

*2021-10-16, version 12.4.0*

Upgraded to pro lifetime but still getting blocked

### 1/5 — No stars earned for poor communication skills presented at this time

*2021-06-04, version 12.3.0*

Improve hospitality less friction in communication.

### 1/5 — Garbage

*2021-02-06, version 12.2.2*

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

### 1/5 — Worst ever

*2020-05-28, version 10.1.1*

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.😬🤮🤢🥱😿😾

### 1/5 — Not many functions in free version

*2020-03-03, version 10.1.1*

The pro version looks good but the free version has very little available.

### 5/5 — Meatohead

*2026-01-06, version 15.0.0*

What an amazing app EE Toolkit excellent well done

### 5/5 — Chip Sicherungen (SMD)

*2025-12-14*

Wäre schön wenn man im der App noch Chip Sicherungen mit den Code Bezeichnungen z. B. Typ E = 375mA und die Baugrössen in Millimeter mit aufnehmen könnte.

### 5/5 — Engineer

*2025-09-09, version 14.0.0*

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.

### 5/5 — Parfait !

*2025-09-04*

Il manque un tableau de conversion pour les farad par exemple, il manquerait aussi la version française de l’application :)

Mais déjà merci ! J’ai pris la version payante et c’est chouette ! Ça aide énormément.

### 5/5 — Keep the updates coming

*2025-09-02, version 14.0.0*

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.

### 5/5 — The old Russian lady

*2025-08-03, version 14.0.0*

Adobe fresh American would love something like this.

### 5/5 — Great app

*2025-04-20, version 14.0.0*

A well supported app that I used  for many years.

### 5/5 — Bestens

*2025-04-19*

Leute, mal ehrlich. Da hat sich einer wirklich viel Arbeit gemacht, alles  für umsonst, und dann funktioniert das auch noch so wie es soll.  Großen Dank

### 5/5 — Very useful

*2025-03-25, version 13.7.0*

Love it! Thanks..

### 5/5 — Extrem nützlich

*2025-03-11*

Alle Formeln, Diagramme und sehr viele Datenblätter in einer App zusammengefasst - für mich sehr hilfreich, volle Punktzahl. Ich habe trotzdem ein paar Wünsche: zB eine Möglichkeit, selbst Bauteiledaten einzutragen, mit Link zu einer Website oder einem PDF. Momentan finde ich einige meiner Bauteile einfach nicht in der Liste - wäre ja auch ein Wunder, wenn wirklich alle erfasst wären. Ebenso wäre eine Bauteilesuche über alle Kategorien hinweg nützlich; manchmal weiß man eben nicht, ob ein bestimmtes Teil zB unter „BJT“ oder „Leistung“ zu finden sein wird. Noch ein kleiner Wunsch: Sortierung und Kennzeichnung der Kategorien verbessern, zB Gruppierung nach Formel/Schaltung/Bauteildaten und jeder Kategorie ein kleines Icon für die Gruppe mitgeben. Wenn man die App nicht täglich über alle Kategorien hinweg benutzt, sucht man derzeit manchmal, bis man die richtige findet. Die Kategorie-Icons sind auch nicht sehr einheitlich (mal Schaltzeichen, mal realistisches Bild, hier könnte man nachbessern). Das ändert aber alles nichts an der enormen Nützlichkeit und der sehr guten Gesamtbewertung.
