Think with your hands.
Place gates and connect them with touch or Apple Pencil. A clear grid and right-angle wires keep the idea readable as it grows.

Small pieces.
Clearer thinking.
Room to experiment. Tools to understand what happened. For learners aged 13 and older.
Build once. Look inside.
Turn a circuit into a reusable custom block. Open it while it runs to inspect what is happening inside, without losing the bigger picture.
Custom blocks · Live debug-insideFollow the why.
Step through propagation, revisit history, and read waveforms. Explore the same logic through truth tables and Karnaugh maps with minimization.
Step · History · WaveformsGive it a clock.
Explore sequential logic with clocks, D/T/JK flip-flops, multiplexers and a built-in 4-bit shift register.
Keep ideas together.
Organize circuits in folders, rename or move them, and recover deleted work from Trash. Use native project files to carry a circuit and its reusable blocks to another device.
In your language.
Work in Polish or English. Designed primarily for the space of iPad, with iPhone support too.
