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.

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.

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.

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.

★★★☆☆ United States · v13.2.0 · 17 Aug 2023

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.

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.

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? 🤷🏻‍♂️

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!
