Build a little computer, one working machine at a time. Wonder Circuits is a hands-on digital logic lab for iPhone and iPad: connect a switch to a lamp, make a clock pulse, add binary numbers, then explore a visible 4-bit computer. 71 guided experiments across 13 chapters turn Boolean gates, timing, carry, memory and control into machines you can build and run. Connect parts, change an input and see what happens. Review what you learned in the concept handbook. The complete Invent Lab is free: build your own logic machines, adjust parts, save reusable modules and share offline blueprints. The first 12 campaign machines are also free. One optional purchase unlocks the remaining 59 machines and all future core content. No subscription or consumables; campaign levels still progress in order. Works offline. No accounts, ads or tracking. This is a digital-signal learning sandbox, not an analog electronics simulator: it does not model voltage or current.
