One app. One kit. Infinite robotic adventures!

DLD is a digital logic design and circuits workbench for your phone. Drop gates onto the bench, wire them together, flip a switch, and watch the signal travel through the circuit in real time. Built for students working through a digital logic design course — and for anyone who wants to see Boolean algebra actually do something. BUILD ANYTHING • 28 components: switches, clocks, Vcc and ground, every standard gate, tri-state buffers, multiplexers, flip-flops, displays and probes • Gates take 2 to 8 inputs — one wide NAND instead of three cascaded ones • Tap a component to reach its settings: input count, clock speed, colour • A work bench far bigger than the screen, with pan, zoom and fit-to-circuit SEE IT WORKING • Current animates along every live wire, so you can follow a signal • LEDs, LED bars, 7-segment and hex displays light up as the circuit runs • A school bell that rings for as long as it has current • Logic probes read out 1 or 0 anywhere you wire one UNDERSTAND IT • Boolean equations written out from whatever you have drawn • A full truth table generated from your circuit, ready to copy out • Conflicting drivers on a net are flagged rather than quietly wrong • A tutorial section covering every gate symbol and its truth table KEEP YOUR WORK • Save and reopen as many circuits as you like • Undo and redo everything • Recolour wires, lamps and blocks however you want to read them COMPONENTS Switch · Clock · Vcc · GND · AND · OR · NOT · NAND · NOR · XOR · XNOR · Buffer · Tri-state buffer · Tri-state NOT · MUX · DEMUX · D flip-flop · T flip-flop · JK flip-flop · Virtual links · LED · LED bar · 7-segment · Hex display · Bell · Probe · Label PRIVATE BY DEFAULT No account. No sign-in. No analytics. No ads. Nothing leaves your device — your circuits are saved on the phone and nowhere else. The app works with no network connection at all.
