Reckon vs Causal Loop Diagram

A record of how you decide, more than a decision journal or decision tracker. Most decisions feel resolved the moment you make them. Reckon keeps the prediction, the confidence, and the reasoning. Over time you can see how your judgment holds up. CALIBRATION, FINALLY SOMETHING YOU CAN SEE Every decision in Reckon starts with what you think will happen and how sure you are. Over months, that turns into a record you can read: confidence over time, predicted vs. observed, the difference between the calls you make well and the ones you only think you do. INSIGHTS THAT LIVE IN THE LONG TERM After fifty decisions, the patterns appear. After a hundred, they're hard to ignore. Reckon surfaces them: where confidence overshoots outcomes, where it undershoots, which domains your judgment is sharp in, and which ones still need work. RESOLUTION, THEN A SECOND LOOK When a decision resolves, you log what happened, whether the call was correct, and how satisfied you are with it. Thirty to sixty days later, Reckon asks again: would you make this call again? The two answers are rarely the same. CHECK-INS FOR THE MIDDLE OF A DECISION Between making a call and finding out how it went, things change. Check-ins capture new information — tagged positive or negative — and update your confidence. The middle of a decision is where the information arrives, and Reckon keeps it in the record. RESOLVED DECISIONS, AT A GLANCE Browse the calls you've made. Filter by domain, by satisfaction, by whether your follow-up still agrees with you. The library you wish you'd been keeping for years. ONE LIST, BY REVIEW DATE Every open decision, organized by when you said you'd come back to it. No notifications competing for your attention. Only the calls awaiting your next look. A TIMELINE PER DECISION Each decision has its own confidence chart: check-ins as points, tagged shifts as annotations. Watch the moment your thinking changed, and what changed it. BREAKDOWNS BY DOMAIN Career, finances, health, personal. Each domain has its own calibration curve. See them separately, then compare. Reckon is iPhone and iPad, one-time purchase. Buy it once and it's on every device you sign in with. Your data syncs over iCloud. Nothing of yours sits on a server we run. No subscription. No account. Less journaling, more calibration.

"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.
