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 accommodating 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.
Supports iOS 12.x back to iOS 9 and all Apple iPhone and iPad models including 7, 8, X, XS, XR, plus, max and all iPad pro models.

Ratings and Reviews
Convenient Practical for Hobbyists AND Engineers
Marcus has developed a great iPhone app for electronic hobbyists and engineers to have handy in your pocket. It provides handy reference to pinouts, specs, component markings, formulas, calculators, electronic related physics reference, on and on, in an easy to navigate and use format.
I use it to explore microcomputer chips, both pic and atmel, when beginning a project away from my computer and with a little time to kill while waiting for whatever.
Even when at my computer, it is great to look up this and that without having to radio-button back and forth between so many windows, or having to print something out just to refer to while I'm working.
Marcus has been updating and expanding this app for years now, and doesn't keep hitting his customers up to pay and pay for updates like some developers do, nor does he abandon the app when iOS requires compatibility updates.
If you are an active hobbyist or a napkin-doodling engineer, you will not regret purchasing this app!
Extremely Comprehensive-Worth it!
I've been trying to learn how to create circuits for the past year or so and this app is by far the greatest reference I've come across. In addition to the vast amount of data sheets and various formulas, there is a way to make a list of parts one may need to complete a project which is very useful. Finally, the developer is very active and always looking for ways to improve the app, if he/she keeps that mind set(without adding too much in one app), this may be the go to reference for electronics and components. Great job and I definitely recommend the app!
Every Electronics Person Should Get This App!
Before I got this app, i sent the developer a email on whether you could design your own Circuit Schematics. They answered me back in less then 24 hours. I got the app. Went to go make a test Schematic, just to get the hang of it. I was blown away! It is better then I could have imagined!
They also have parts where you can solve the value of different components. For example, you can solve anywhere from a Resistor, to a Coil.
As a student doing online college to become a Electronics Technician, this app is a huge help! Glad I found it!
If you ever have a question, they answer it, and they do it quite quickly!
Whether you are a Student like me, or been in the Electronics industry for years, Electronic Toolbox Pro is a must for anyone who dose Electronics!
Glad I found this app! Thanks for making it Marcus Roskosch!
