Thanks for continually updating the app. ### 4/5 — Eigentlich gut *2024-02-25, version 13.4.0* Aaaber die GUI ist nicht optimal. Lieber ein simpler weißer Hintergrund als das Grau. Texte sind teils viel zu klein und die Navigation gewöhnungsbedürtig. Einige Bilder bei den SBCs sind recht pixelig. Hier wäre auch eine simple Vollschirmdarstellung besser zum Zoomen. Bei den Transistorschaltungen fehlt der positive Stromquellenanschluss Vin. Dennoch eine sehr umfangreiche Sammlung. ### 5/5 — Best Electronic app *2023-11-03* I use this app all the time and love it. It makes my job easer with all the formulas in place. If you are in any electronic field of service you need this app! ### 5/5 — Pi pad calculator *2023-11-01* Thank you for adding the option to add resistor values to create a pi-pad! Now the rest of the Technicians at my company can use values that we have in the stockroom to design pi-pads for our DDC product line. Big help! 😀 Mark **Developer response:** Hello Mark! Many thanks for your feedback! The EE ToolKit already supports a Pi attenuator calculator. You can find it in the "Basic Tools" section of the App. If you are looking for something different, please just send an Email to tom@ee-toolkit.com. Many thanks & all the best, -tom ### 4/5 — Pi pads *2023-06-14* To the developers. I need to be able to input resistor values when I am at work to make a pi pad. If you can implement this function then I know of a few Engineers at work who may consider purchasing your app. I will leave 5 stars if you can implement this function for us. Thank you! Mark K. **Developer response:** Hello Mark! Many thanks for your feedback! The EE ToolKit already supports a Pi attenuator calculator.

Many thanks & all the best, -tom ### 5/5 — Super! *2023-04-17, version 13.0.1* Eine sehr gelungene App für den Hobby- Elektroniker. ### 5/5 — Cool *2023-03-12* Everything you need ### 5/5 — Excellent group of tools! *2023-03-04* One question : There appears to be an issue with the 7400 routine. Upon selecting it closes the entire app. Running IOS 16.3.1 **Developer response:** Hello and many thanks for reporting that bug. It's a regression that got introduced in the last version of the App. Apologies for that. A fix is already on the way. Thanks & best regards, -tom ### 5/5 — hope *2022-11-03* Chinese is not supported ### 5/5 — Molto utile *2022-08-30, version 12.6.1* Molto utile ma mi piacerebbe una traduzione in lingua italiana! ### 5/5 — Exellent *2022-08-13, version 12.6.1* Exellente applique facile d’utilisation je conseil ### 5/5 — Excelente app *2022-06-27, version 12.6.0* Una de las mejores. Vale la pena tenerlo. Es de mucha ayuda y constantemente la actualizan. ### 5/5 — Great app!! Please update SBC section :) *2022-06-06* The tools available in this handy app are incredible. Take the time to explore and experiment. Please add Teensy 4.1 to the SBC section. ### 5/5 — Great App *2022-06-04, version 12.5.2* Best quick reference guide I’ve found for electronics theory and calculations. ## Most critical reviews (10 lowest-rated) ### 1/5 — 垃圾 *2026-04-01* 垃圾 ### 1/5 — Gone downhill *2025-02-08, version 13.6.0* This app has many errors. I tried to reach out and have yet to recieve a reply. I would not recomend this app. States a 100 mhz antenna is 9 feet. ### 1/5 — Don’t Buy *2022-12-29, version 12.7.0* This is not a circuit builder ### 1/5 — 2 x mal bezahlt für einen Programm Wuche Schrott *2020-02-22, version 12.1.0* 2 x mal bezahlt für einen Programm Wuche Schrott ### 1/5 — Regular *2015-03-26, version 8.1.3* Not datasheet bc 547. O aplicativo tem um ótimo layout, oferece o básico .para fins didático falta informações. ### 1/5 — Save your money *2014-05-20, version 7.4.0* This is the worse purchase I have ever made! ### 1/5 — Läuft nicht unter iOS 7 - Flache Umsetzung *2013-09-16, version 6.0.0* Die App stürzt unter iOS 7 (Golden Master) an etlichen Stellen ab. Die Umsetzung ist extrem flach. Von einer Pro Version hätte ich mehr erwartet. Die Benutzeroberfläche ist extrem Gewähnungsbedürftig. Fazit: für viel Geld wenig Masse und ohne Klasse ### 2/5 — Where is coil wrap calculator ? *2022-08-31, version 12.6.1* Sorry I mixed The apps. Electronic TB what I looking for. But it’s not changed my opinion about your app Old version is more capable then this version. Also there is no search function. I used for years this app. But now totally disappointed ### 2/5 — Boring and limited functionality *2013-03-22* I was looking for an app that would be useful for second year electronics students. This app is more unit able for engineering technologists but leaves a lot to be desired for electronics engineers. ItronixPal has similar features. ### 3/5 — Pitch Detector *2025-03-12* Just not working :/ Rubbish! Sort it out! **Developer response:** Hello! Many thanks your message. I just re-tested the Pitch Detector on the latest version of the EE ToolKit and on several iPhones and iPads. It works just fine. Could you please double check if you gave the App permissions to access the microphone? Could you double check if the Audio Scope works? If you gave the App microphone permissions and the Pitch Detector still does not work, please try to delete the App and re-install it. Also, please write directly to tom@ee-toolkit.com. That's easier to follow up. Thanks very much, -tom ## Most praised reviews (10 highest-rated) ### 5/5 — Top *2025-11-12, version 15.0.0* Best investment ### 5/5 — This app i am using for last 5 years, like it completely help to my work 👍 *2025-07-26, version 14.0.0* This EE pro gives me help really….😊 ### 5/5 — Phénoménal *2025-05-27, version 14.0.0* Merci beaucoup! ### 5/5 — Sehr gut *2025-04-21, version 14.0.0* Spitzen E-Tool, dass es derzeit gibt! Danke! ### 5/5 — Great App *2025-04-21, version 14.0.0* A must have for electronics ### 5/5 — Top app *2025-04-19, version 14.0.0* Of all the apps on my iPhone (and I have way too many), this is the only one that I am truly happy that I found and installed! It brings a smile to my face having all this information in one place and so convenient. It is obvious that the developer fully understands the use cases and probably uses it himself regularly. Sure, it has a couple shortcomings and a couple missing things, but it is great nonetheless. And the new zoom changes make it even better. Another thing that might be a nice add: hot links for newbies. It seems I always have to have a handful of bookmarks open in my browser to remind me the background behind how/why some concepts work. Also landscape mode would be nice in some cases - especially when zooming. ### 5/5 — Absolutely AMAZING app *2025-02-26* This app alone is well worth the cost of the bundle. This is great for students to engineers. This is invaluable for frequency work. ### 5/5 — Perfect EE Toolkit *2024-12-25, version 13.6.0* This app is fantastic. Where have you been all my life! ### 5/5 — Great app *2024-12-17, version 13.6.0* Very helpful ### 5/5 — Thanks for the updates and adding more tools *2024-06-29* Thanks for the updates and adding more materials.
