Well worth the money *****
I researched all EE apps before buying this one and I have to say that this one is the best by far. The developer is very accomodating to requests and suggestions and provides updates frequently. Very, very happy with this app.
Simply brilliant *****
I don't normally review apps but I was so impressed with this one I felt I had to make a brief comment. Buy it, I promise you won't be disappointed.

Version 9 of the app has just been released and as always, this update is FOR FREE to all users of Electronic Toolbox.
At this point, many thanks for the ideas and suggestions I have received from the huge user community. You helped me to keep on improving my app with every new update.
This App will continue to live and grow over the time. So I still look forward to all additional ideas, suggestions or even criticism so that I can continuously improve my app.
New Data Update January 28.2016:
■ Happy Birthday Raspberry Pi! Raspberry Pi 3 added
■ AN1431T and M Variable output shunt regulator added
■ new Arduino Pro Mini with ATmega328 added
■ TMP35,36 and 37 Low Voltage Temperature Sensor added
■ Arduino SparkFun added
■ USB Type C added
■ Several other database updates and corrections are included
New Data Update December 13. 2015:
A new Data Update 9.02 is available with the following changes:
■ Additional Coax Types (Belden)
■ Mini-DIN Sockets added
■ HAM Radio RIG Socket Pinouts
■ Aviation Pinouts
■ Additional data and information for the packages tool
■ The Tubes had lost their Pinout images for some reason. They are now back, sorry.
Quite a few amendments and corrections for the existing databases
The new App Update 9.01.01 contains the following changes:
This version contains new tools, many feature improvements and of course some bug fixes.
■ Optocoupler Database – This new Database tool contains more than 400 Optocoupler types including description and pinout
■ Packages Database – This new tool contains more than 300 Package types like DIP, DIP, TO, SIP, SOT etc.
The following new features have been implemented:
■ iOS 9
Electronic Toolbox and RF-Toolbox are now not only fully compatible with iOS 9 (while still backward compatible down to iOS 7), they also support new features introduced with iOS 9 such as:
■ Split view (use the App side by side with another App)
■ Multitasking (App will continue to run in Split view)
■ Improved user interface on iPhone 6 plus and 6s plus in landscape mode
■ Now it is possible to directly jump to the compatible types listed inside the transistors, FETs etc.
■ You can now also directly jump to the 74xx and 40xx ICs from inside the Logic tool
■ The Battery charge tool can now also calculate discharge
■ Improved Database parametric filtering
■ Substrate Dielectric can now be selected (e.g. FRA4, GETEC, Polyimide etc.) in the PCB tools (RF-Toolbox only)
■ The voltage divider now also displays ratio between R1/R2 and V1/V2
■ Generator, Scope and Frequency counter now allows input and output either on built in speaker / microphone or headphone plug
■ Upon request, the Frequency tool can now again convert between Period/Frequency/Wavelength
■ Tools like the Raspi tool now have “Useful links“
■ The PV 4-20mA tool now shows sample values in 10% steps (linear and square root)
Improvements in the Projects section:
■ Many additional components added
■ The component browser now allows to search for component types
■ Inside the project, you can now directly jump to the corresponding tool for a certain component. This way, you can now easily double check the pinouts, datasheets or color-code directly from inside the project tool
■ The Battery plot function is now working again
■ Some corrections in the parametric filters
■ Some corrections in the calculation of the Toroid tool
■ Some general corrections in the transformer tool
■ Three ring m Ohm values are now accepted in the Resistors tool
Please note, as mentioned in my blog on electronic-toolbox.com, there will soon be some additional updates. If you experience some issues or have additional requests or ideas, please let me know quickly so I can consider this for the next update.
Thank you all for your great support!
