Current Circuit Builder

In this sandbox game you can build almost any digital logic circuit you can imagine. The electronics are abstracted away to let you focus on the digital logic. Begin by creating simple circuits like blinking light bulbs and memory which can store values, and as you learn more about the components you can advance to creating more complex projects, e.g. a small 4-bit computer.
List of various features:
* Keep separate circuit boards for different projects.
* Components include: wires, logic gates, buttons, switches, delay elements, true random generators, vibration motors, loudspeakesr, bulbs and 9 different ICs for more complex tasks.
* Controls: component placing, component configuration, rotating components, multi tile selection, copy-pasting, zooming and more.
* Easily maintain backups of your boards to be safe if something goes wrong.
* Explore settings for customizing the app.

I like this app! Only issue is that it force zooms out on my galaxy S7 and I can't zoom back in, at which point the current project is unusable :/

super bad. there is no "delete" button and once you place something you can't move it again. if you make a mistake you have to close and restart the app and delete all your progress. please fix this if you want a functional app

its ok, the ui is a challenge to work with and seems to be missing key components.

Second best to Minecraft. I really wish the dev would keep working at it and stuff. Has a lot of potential.

If feeding and exercising the brain is called for, this is the app to get...and, it is asperger's friendly! Bordering on the line of becoming unhealthy - i cannot stop using it. I'm looking forward to the new upcoming update which hopefully will include tons of new 'gucci' things to play with and solve the periodic crashing issue. Toby, you are a legend man! Keep up the great work dude! edit December 2018: is there an app update coming? :)

This is a great logic simulator, I love it, but I have just one suggestion: the ability to create custom ICs. This would be great with more complex circuts, as it could really cut down on space and help manage the circut. That's all, really. Again, fantastic simulator!

One of the best Android Apps I ever came upon! I'm just sad that there's no more online functionality.

The startup UI improved cosmetically from the last version, though, It still needs more important chips like flip flops, binary counters and what not

I can't zoom in I can't expand a wire and in all its just a waste of time

Cant move the components when you place them and you cant rotate or delete parts

Awesome concept, pretty good execution, but tedious editor, and frequent world corruption!

M. K. Feb 18, 2017     

Has a bit of an aesthetic weakness but it's pretty damn functional.
