Decisio: AI Decision Maker
Weigh Trade-offs, Choose Smart
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Indecisive about a job offer, big purchase, or move? Decisio breaks any choice into criteria + options and ranks them.
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.
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. Every number traces back to your inputs. Share your reasoning with a manager, partner, or team.
SYNCED AND PRIVATE
iCloud keeps your decisions available across iPhone and iPad. All data stays in your iCloud account. No third-party servers. No ads. No data selling.
