Decision Maker vs Reckon

An application that helps you make accurate decisions based on reason and logic, so you are less likely to regret your choice. CORE FEATURES PROS & CONS This is a binary decision tool where you add positive and negative arguments. Each entry has a customizable weight, and the app calculates a net score to determine a "Yes" (Blue), "No" (Red), or "Undecided" (Amber) verdict. Key features: - Unlimited dilemmas, intuitive visuals - Add pros and cons and adjust their weight (importance) - Dark mode and light mode for you to choose - Your concerns will become transparent and clear COMPARE OPTIONS (DECISION MATRIX) This feature is designed for choosing the best option among multiple alternatives (e.g., iPhone vs. Samsung vs. Oppo vs. Xiaomi). You can define columns (Options) and rows (Criteria like Price, Battery). You rate each cell on a scale (1-10), and the app calculates a weighted sum to highlight the winning option. SWOT ANALYSIS This is a strategic planning tool for bigger picture thinking. It utilizes a 2x2 grid where you categorize factors into Strengths (Internal/Positive), Weaknesses (Internal/Negative), Opportunities (External/Positive), and Threats (External/Negative) to visualize the viability of a project or career move. 10-10-10 RULE This is a temporal framework to combat short-term emotion. It asks you to predict how you will feel about a decision in three specific timeframes: 10 Minutes, 10 Months, and 10 Years. This feature is text-based and reflective, helping you gain long-term perspective. The 10-10-10 rule can help you avoid FOMO (fear of missing out) and impulsive decisions, and minimize long-term regret. DECISION TREE For a choice with several paths, not just two. Lay each option out as its own branch, hang the reasons for and against it underneath, and weight them. The app scores every branch and shows which one is ahead, so a tangled decision becomes something you can actually see. OTHER FEATURES - The app supports both light mode and dark mode. Pick the one that fits your eyes. - The app can work totally offline. No internet connection is required. - You can export your data into a JSON file for backup (e.g, when you change your phone) or import/ restore your old data. - The app supports local authentication. You can use Face ID to lock the app to keep your decisions private.

Reckon ranks hypotheses by what hasn't been knocked down — not by what has the most support. Most decision tools let you write a long pros-and-cons list and call it analysis. That doesn't help — you can rationalize anything in prose. Reckon makes you compare every piece of evidence against every hypothesis and ranks them by Heuer's ACH technique (the method CIA analysts use): fewest refutations first, with a tiebreak on most support. WHAT YOU GET • A starter library: pick from six pre-built example boards (shortseller, founder, researcher, investigator, life decision, doctor) or describe your situation in a paragraph and let on-device AI seed the matrix for you. • Inline bias guardrails: when one hypothesis collects evidence all in the same direction, Reckon flags it. "Bears out" without "Cuts against" is the structural signature of confirmation bias. • Falsifier pre-commitment: state up front what evidence would prove a hypothesis wrong. The app reminds you whether that evidence ever showed up. • Steel-manning before ruling out: before you dismiss a hypothesis, Reckon asks for the strongest case for it. Stops you from throwing out the right answer too early. • Pre-mortem: after you reach a conclusion, the app asks you to imagine being wrong about it in a year. Catches wishful thinking that even refutation-first scoring misses. • Calibration tracking: when you finalize, set your confidence (0–100%) and a check-in date (1 week to 1 year). Come back when the date arrives, log the actual outcome, and Reckon shows your calibration curve over time. Are you actually right when you say you're 80% sure? • Strict Bayes mode (optional): set explicit priors per hypothesis and the matrix shows real Bayesian posterior probabilities updating with each rating, using likelihood ratios per Tetlock/Heuer convention. Real probability, not a heuristic. • Plain English mode: turns off the celestial vocabulary if you'd rather see "Hypotheses / Evidence / Matrix" than "Stars / Observations / Star chart." Same depth, less poetry. • Templates: save your hypothesis structure (e.g. forensic-accounting suspects, differential-diagnosis options) for reuse. Faster on your 12th board than your 1st. PRIVACY Local-only. Your boards, evidence, conclusions, and calibration history stay on your device. No server, no analytics, no ads. AI seed runs entirely on-device via Apple Intelligence — your situation never leaves your phone. WHY ACH Confirming evidence is cheap. Refuting evidence distinguishes. Most decision tools amplify confirmation bias by rewarding biggest positive sum. Reckon does the opposite. iOS 17+. AI seed and Strict Bayes posterior require iOS 26+ on Apple Intelligence-capable devices.
