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.

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!
An impressive reference
Wow! I was absolutely blown away by the sheer amount of content in this app. I discovered this when I was using a competing app that I found very lacking, especially in the area of microcontrollers. I decided to take a chance on this one and was just blown away by how much more content was in this one.
I would love to see more microcontroller/SBC content added, like more boards and pinout diagrams for the existing library. Seeing the frequency of updates, I’m hoping that will continue to evolve and I’ll be submitting some more feature requests. Super impressed, keep up the good work!
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!
