Systemiq is the AI-powered systems thinking tool for curious minds. Understand how anything works, why it exists, what could break, and what happens next. Most people see the surface. Systemiq helps you see the system underneath. Whether you're exploring how a stock market functions, why hospitals are designed a certain way, diagnosing a real-world problem, or planning a major goal, Systemiq turns your questions into structured system maps in seconds. ANALYZE ANY SYSTEM Ask about anything: business, technology, biology, infrastructure, psychology, economics, society, and more. Systemiq breaks complex systems into components, flows, inputs, outputs, dependencies, bottlenecks, and failure points—so you can actually understand what’s going on. REVERSE ENGINEER REALITY Why does the QWERTY keyboard exist? Why are supply chains structured the way they are? Why do certain systems outperform others? Systemiq reveals the hidden trade-offs, forces, and design decisions that shape the world around you. PLAN LIKE A SYSTEMS THINKER Turn goals into execution systems. Describe what you want to achieve, and Systemiq helps structure the moving parts: priorities, risks, phases, dependencies, and actionable next steps. DIAGNOSE WHAT’S BROKEN Car won’t start? Team communication keeps failing? Workflow keeps collapsing? Systemiq helps you trace the breakdown, identify root causes, and understand where the system failed. EXPLORE WHAT-IF SCENARIOS What happens if gravity doubles? What if AI replaces a major industry? What if remote work becomes permanent? Simulate cascading consequences and explore second-order effects with AI-guided systems analysis. BUILD CONNECTED UNDERSTANDING Knowledge shouldn’t live in isolated fragments. Systemiq helps connect ideas across domains, helping you recognize patterns, relationships, and recurring system principles. FOR PEOPLE WHO WANT TO UNDERSTAND, NOT JUST MEMORIZE Systemiq is built for thinkers, builders, students, entrepreneurs, problem-solvers, and endlessly curious minds. Because everything is a system.

Causal Loop Diagram

Features
Read full description

"Causal Loop Diagram" is a fast, focused editor for sketching causal loop diagrams (CLDs) on iPhone — a foundational tool of systems thinking. Place variables, draw arrows, set polarities (+/−), and the app automatically detects feedback loops and classifies the whole diagram against well-known systems-thinking archetypes. — Features — ■ Simple drawing • Tap empty area to add a node, then tap source → target to link • Long-press an arrow to add a delay marker (||) • Drag nodes freely; pinch to zoom; one-finger drag on empty area to pan ■ Automatic loop detection • The moment a cycle closes, an R (reinforcing) or B (balancing) badge appears • Each loop is numbered (R1, R2, B1, B2…) so overlapping loops stay distinguishable • Tap a badge to highlight that loop's interior; other loops dim ■ Nine archetypes auto-classified • Reinforcing loop / Balancing loop • Limits to Growth • Fixes that Fail • Shifting the Burden • Escalation • Success to the Successful • Tragedy of the Commons • Growth and Underinvestment ■ Seven curated samples Familiar themes — study, family, sibling rivalry — to learn each archetype by example: • Study Habit (R) • Calibrating to Target Score (B) • Limits to Growth: Fatigue • Shifting the Burden: Escapism • Fixes that Fail: All-nighter • Escalation: Sibling Rivalry • Tragedy of the Commons: Parent's Attention ■ Privacy • No network access at all • No account, no sign-in • No analytics or tracking SDKs • Diagrams stored only in UserDefaults; uninstalling removes everything ■ Other • Japanese / English UI, one-tap switch • Save multiple diagrams locally with custom names • iOS 16+ (iPhone 8 and later) — Who is this for — • Students of systems thinking and system dynamics • Managers and designers who think in structures • Anyone who wants to step back and see the loops in their own habits, relationships, or work • Educators preparing diagram examples on the fly Pairs naturally with Peter Senge's "The Fifth Discipline" and other systems-thinking textbooks — turn the loops in your head into something you can draw and touch in seconds.
