This is the brand-new Electronics Engineering ToolKit! The HIGHLY RATED and RECOMMENDED productivity app. Users say it is the BEST and MOST PRACTICAL Electronics App in the whole App Store. From an electronics enthusiast with a master's degree in Electronics Engineering. This App is for engineers, students and hobbyists and anyone interested in Electronics Engineering. The App gets CONSTANT and POWERFUL improvements! !!! This is a UNIVERSAL App - for iPhone and iPad !!! With In-App upgrade to PRO. If you don't like In-App purchases, you can also download the PRO version (red icon with PRO text) which is full PRO from the beginning without any In-App purchase. WHAT OTHER USERS ARE SAYING: “Awesome app, constant and powerful improvements” This app was worth every penny I paid for it back when I bought it years ago. Since then, I’ve regularly used it at work and found it to be an excellent, quick tool to use. The most impressive aspect of this app are the constant and VERY impressive updates! Massive feature additions and very easy to use interface! The list of capabilities this app has makes it an amazing value for truly anyone involved in electronics. “Latest version makes this an exceptional tool” The EE Toolkit was always a very useful tool, but with the additions in the latest version it is truly an exceptional tool. The author is extremely diligent in managing bugs and improving the tool. “A superb app highly recommended” Fantastic application. Very useful. Always updated. Good developer. Lots of great bonus tools. Just love it. "Incredible useful, worth the money" I have had this app for a while now. Originally as an Electrical Engineering student I didnt really use it but once I was out in the field it became my bible. I definitely recommend to any engineering students/professionals alike. I also recommend buying the Pro version because it is definitely worth it. FEATURES OF THE EE TOOLKIT: Ω more than 160 electronic applications Ω amazingly great multi-functional keyboard Ω huge selection of color code tools and SMD code tools Ω audio scope and a frequency pitch detector Ω favorites page only for the tools that you have marked as favorite Ω full-featured frequency generator Ω extra large component reference section (incl. 7400 Series, PIC family, etc.) with the option to open pdf datasheets live or by e.g. iBooks Ω 555 Timer Tools with the most important application examples Ω extensive collection of Single Board Computers (more than 120 different boards!!!) Ω PCB trace impedance tools for several different structures Ω simple and quick unit conversion within the single calculators Ω fast on-the-fly conversions and calculations Ω real-time circuit simulations of the example circuits Ω support for preferred E series, sliders and min/max calculations Ω auto-save of all entries over several sessions Ω file manager to save and load individual calculations Ω built-in access to your iCloud Ω formula search tool with quick links to the tool which uses the formula Ω and many many more

Read full description

VibraPad is an educational App to teach the basics of vibration analysis for rotating machinery monitoring, diagnostics and maintenance. It contains a library of machines including motor, pump, fan, blower, gearbox, belt derive, and bearings. The user can easily construct a system by connecting the components from the library, define the specification for each part of the system, and see the fundamental frequencies of the system in details and also on the vibration signal spectrum. The App can acquire the vibration signal through an extra hardware that can be purchased separately. However, without the extra hardware, the user can still acquire the sound signal of the machine through the mic of the iPad and the signal will be shown in the time- and frequency-domain. The harmonics of the machine frequencies can be also shown on the frequency signal. Features: - A library of machine components: motor, pump, fan, blower, gearbox, bearings, and belt drive -easy touch and drag-based assembly of the system using the library components - acquiring the sound signal of the machine through the iPad built-in Mic - Capability of the external accelerometer data acquiring if purchased with the extra hardware (contact Motionics for more info) - Live monitoring of the acquired (sound or vibration) signal in time and frequency - Zoom option for the signal in time and frequency domains - Fundamental frequency calculator for all machine components in the library - Report generation for all the machine components with fundamental frequencies - Report E-mail option - Automatic higher peak finder for the frequency signal ******** Note *********** The App requires external hardware to operate, please contact us for more information

Verdict

The call

The clearest difference is price: EE ToolKit at Free against VibraPad's $119.99. EE ToolKit also leads on rating (4.7 vs 4.0) and ratings volume (1.4K vs 1). VibraPad's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 90%). On update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

EE ToolKit holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of EE ToolKit's written reviews are positive against 100% of VibraPad's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EE ToolKit ships an update every 3 months, VibraPad every 4 months. The most recent releases landed on October 12, 2026 and June 5, 2026 respectively.
