Stop overthinking. Start deciding. Decisio uses AI and the Analytic Hierarchy Process (AHP) -- a decision science method trusted in boardrooms and universities worldwide -- to turn complex choices into clear, ranked results. In 10 minutes, you get a defensible answer backed by math, not a gut feeling. HOW IT WORKS Define your decision (or pick a template) Set your criteria and how much each matters Add your options Make pairwise comparisons -- "Is cost more important than speed?" Get a ranked result with confidence scores The AHP consistency check flags when your own judgments contradict each other. No other decision app does this. AI THAT RESPECTS YOUR PRIVACY AI features are part of Pro. On devices with Apple Intelligence they run entirely on your iPhone -- your decision details never leave your device. You can also connect your own OpenAI key instead. Either way, the structured analysis is the same. DEVIL'S ADVOCATE Before you commit, AI challenges your top choice. It surfaces blind spots specific to your criteria, options, and context -- not generic pushback. Available with Pro. YOUR DECISION PLAYBOOK Every decision teaches you something -- if you capture it. Part of Pro. Recipes: Save what worked so you can repeat your winning formulas Principles: Record hard-won lessons so you never make the same mistake twice Source links: Tap any Playbook entry to jump back to the original decision TRACK OUTCOMES, SHARPEN YOUR JUDGMENT Rate past decisions as right call, mixed, or wrong call After 5 rated decisions, see your personal Calibration Score Watch your decision-making accuracy improve over time 15+ READY-MADE TEMPLATES Career: Job offers, career change, relocation Purchases: Car, laptop, home Business: Vendor selection, hiring, build vs. buy Travel: Trip planning, destination comparison Life: Moving, relationships, major commitments PROFESSIONAL EXPORT Export any decision as a polished PDF, Excel spreadsheet, or Markdown document.

Decidd turns a hard choice into a clear call. Big decisions get stuck in back-and-forth: too many options, too many "but what about...". Decidd gives you a simple, structured way through it. How it works: • Name your decision: type it or just speak it. • AI suggests the options you're weighing and the criteria that matter. • Rate how each option does on each criterion. • Set what's important with quick this-or-that comparisons. • Get a ranked result, a clear winner, and a short explanation of why. Why people like it: • Fast and focused: no clutter, no account, no sign-up. • Works your way: use the AI assist or do it all by hand. • Your data stays yours: decisions are stored on your device and synced privately through your own iCloud. No ads, no tracking, no analytics. Your Pathfinder to Lift-off.
