Ratings and Reviews
It 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.
Developer Response ,
Thank you for trying the app and leaving such a thoughtful review. I very much appreciate your feedback, and will work towards adding more components and tutorials in addition to UI improvements.
It might take some time to implement all of the improvements, but I hope to continue providing you and all other users an updated and improved experience over time. I will continue working and improving until I can earn 5 stars.
Your suggestions are excellent - if you think of anything else that could help improve the app for you, please don't hesitate to send me a message in the app or via email at support@breadpad.com
Love 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!

Thank you for trying the app and leaving a review.
I'm sorry for the inconvenience! I'm looking into this right now, and will roll out a fix soon.
Very 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.

Thank you for using Breadpad and for taking the time to review the app. I am very happy to hear it has helped you.
I appreciate your feedback - it helps me prioritize features for future updates, and I hope to continue improving Breadpad until it includes everything you need to continue building.
Best of luck, and please do send me a message any time if you have feedback or questions at support@breadpad.com
