Show me the easiest way to use this, I have the iPad which this app is recommended for. I also have the Apple pen. Every attempt that I have made to draw or design with the pen And or my finger does not allow me to do anything. I purchased the app and it’s basic version. As of right now, it’s a great concept, but not user-friendly at all.
Save as not working, used for three days, now no files!!!
Muy bueno para diagramas sencillos. Fácil de utilizar
Need to be able to shorten or lengthen a line.
This helped me out during my apprenticeship. Simple and functional.
Useless it has no drag to draw circuits. Don’t waste your time.
I like the app so far but it lacks universal symbols such as resistors and the ability to alter wire colors or shape colors. It will be nice to also have the ability to fill in background colors for distinction purposes. I work with the automotive industry and while this is helpful, it LKQ most of the symbols used in the auto industry
The “free” version has a lot of nice features, but you have to spend a lot of time figuring out how to use it.
I have used this app a few times now and it works great for what I need thanks!
Is not possible to use
