Electronic Toolbox Pro

Engineering reference materials is a classic app domain for pocket oracles, and some of them have become quite polished in very focussed topic areas. What makes this app so valuable to me is that I need not remember which one of several apps holds the golden ticket for the task at hand. The cherry on top is that said convenience doesn’t require diluting expectations as to coverage or sophistication. The only advice is that time spent perusing the embarrassment of riches will be well rewarded, and there is always something else to be explored. I don’t know an engineer who would consider this a bug, but rather a feature.

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!

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!
