CM Logic With Fun

Place gates, wire them, see instantly what happens: propositional logic and digital circuits with a learning path, a reference and a certificate. Offline, no account.

CM Logic with fun is the iPad app for propositional logic, digital circuits and logic gates – made for grade 10 at grammar school, but for anyone who wants to understand how computers “think”.

You build circuits on a free workbench: place components, connect them with wires, flip switches – and wires and lamps light up instantly. For every circuit the app automatically creates the term and the complete truth table.

WORKBENCH

• Switch, clock, push button, constant 1/0 and counter 0–9 as inputs
• Lamp and 7-segment display as outputs
• Buffer, AND, OR, NOT, NAND, NOR, XOR and XNOR gates
• Truth table and term live next to the circuit, tap to copy the term
• Step through the table row by row and look at the result in peace
• Select tool, undo/redo, zoom and overview
• Standard symbols or classic gate shapes
• 18 ready-made examples: half adder, full adder, De Morgan, two-way switch, multiplexer, traffic light on the counter, prime detector and more
• Save, duplicate, share and reopen your own circuits

LEARNING PATH

• Guided course in stages: from the statement through AND, OR and XOR to circuits with gates
• Lessons with text, practice circuits to try and questions
• XP and levels keep you motivated; a certificate as a PDF with your name waits at the end

KNOWLEDGE

• Reference with 18 chapters: basic terms, all logic gates with function, example and truth table, rules of calculation and De Morgan, terms and tables, binary numbers, adders and glossary
• “How is a NAND built?”: from the transistor to the gate, with graphics to try out
• Headings on the left, content on the right – optimised for iPad

EXPORT

• Share a circuit as a multi-page PDF with term, truth table and detail pages, as an image or as a circuit file

PRIVACY

• No account, no ads, no tracking
• All data stays on your device
• Works fully offline
• German and English

CM Logic with fun is available for iPad only.
