No LED options?

How about add in some simple LED options? I’m going to find an app that does.

説明が足りない

Not very user friendly

I love the concept of this app, but it’s just not user friendly. I’d love to see a complete over view of what components you had. But it’s just not quite there yet. This app has potential, if only the developer listened to the users.

Odd 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!

Can’t do anything with it

There is no component toolbox, so I can’t even get started.
