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 On devices with Apple Intelligence, the AI runs entirely on your iPhone -- your decision details never leave your device. On all other devices, connect OpenAI for smart suggestions. Both paths give you the same structured analysis. 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.
