1. 4/5It can always be better and come something great

   I absolutely love the concept but it needs some work. I am currently studying electrical engineering and saw this app on a Instagram ad and thought it looked cool and might help me build a few devices. Unfortunately did not have some of the features I wanted but did not have which is obviously more of a personal opinion but I believed it would help you build more users. Now here’s something’s I would like to see on this: 1. Beginner Friendly Tutorials explaining each component and its use and how to use it on this app. Same goes for the other aspects in this device like coding. Maybe a website or something that you can link to explaining everything. 2. More electric components, such as h-bridges 3. Library for better organized for components. 4. More appealing and better understanding layout. For instance if I was a student or someone younger, this app could be a great learning source for many people and possible collaboration with Apple itself to help many people get into engineering. And help many engineers practice or get better at understanding their work. Go even farther and add physics engines to in the future.

2. 5/5Love the app, but a few minor suggestions.

   I’ve been using this app for 18 months now, and it has been a really big help for me. I’d use it to simulate circuit ideas before actually building them, and I’d learn about electronics on it on the go. Now, I’m working on a relatively complex PCB design, and I need to experiment for a bit with a few concepts before i could move on. First… in the chip library, I didn’t come over any comparators. Either I’m blind, or they’re not there. It would be nice if they were there. Two, if there was an in app basic tutorial for creating custom chips using spice, that would be great as well. Thirdly, a basic electronics handbook that had basic circuits and their calculations would be phenomenal. Lastly, as many people have asked before, LEDs with switches will be great as well! I understand it’s hard to develop something like that, but just asking. Otherwise. I love this!

3. 4/5Very helpful

   This app is awesome, I’m a student going into automation and electrical tech. This has helped me visualize and play with circuits outside of the lab. The only things it’s missing are LEDs and buttons/switches. The chips also take a little long to load but will show up after a while.

4. 1/5Odd design choices!

   It's a virtual breadboard that works on iPads. A breadboard is smaller than an iPad, so I would expect there to be a view that lets you see the whole breadboard. Not the case here. The farthest you can zoom out is '100%' but that shows you less than half of the breadboard. You can see 26 pins of a 60-pin breadboard on a 13" iPad. The pins are 0.1" apart. So you're zoomed in on a 2.6" view of a 6" breadboad. And you can't zoom out any farther to see more of the breadboard. But you can zoom in even more if you want things bigger! You can zoom in to 250% and then you're only seeing a 1" section of the breadboard. Probably a great app for people with serious vision problems!

5. 5/5Fast updates

   Wow, I left a poor review and wasn’t expecting anything but a couple of days later my two issues were addressed. Ok, impressive, definitley going to keep playing with this app to see what’s next. Thanks for the quick rev, I know that isn’t easy.
