Common questions
What is the best decision-making app in 2026?
It depends on what you're deciding. For structured personal
decisions (job offers, big purchases, relocations) Decisio is
the only iOS app implementing real AHP pairwise comparisons with
consistency-ratio validation and an AI Devil's Advocate. For
team voting a tool like ChoiceMap fits better. For
spreadsheet-heavy analysis, Excel or Google Sheets remain
flexible. See the full
2026 comparison.
How is a decision-making app different from a pros/cons list?
Pros/cons lists treat every item as equally weighted: "has free
parking" counts the same as "doubles my salary." A real
decision-making app forces you to quantify how much one
criterion matters relative to another, then ranks options by total
weighted score. That single change usually flips which option
actually wins.
What is AHP (Analytic Hierarchy Process)?
A multi-criteria decision analysis method developed by Thomas Saaty
in 1977. You compare criteria and options two at a time on a 1-to-9
scale; eigenvector math derives the priority weights; a consistency
ratio flags when your own pairwise judgments contradict each other.
Used by NASA, Boeing, the World Bank, and Fortune 500 companies for
high-stakes calls. Decisio is the consumer-grade implementation.
Is Decisio free?
Yes, for the first 3 decisions with Simple Scoring, all 15+
templates, the full Playbook, and full Outcome Tracking — no ads,
no data selling. Decisio Pro ($2.99/month or $19.99/year with a
7-day free trial) unlocks unlimited decisions, AHP pairwise
comparisons, AI Devil's Advocate, and PDF/Excel/Markdown export.
Does Decisio work offline / privately?
Yes. AI runs on-device via Apple Intelligence on iOS 26+
(no data leaves your phone), or you can plug in your own OpenAI
API key for cloud generation. Decisions sync via your own iCloud
account through Core Data + CloudKit. No third-party server stores
your decision content.
Decisio vs Excel / Google Sheets — which is better for decisions?
Spreadsheets are infinitely flexible but require you to design the
scoring model yourself. That's where most people quietly slip back
into "I'll just weight things by feel," which defeats the point. A
purpose-built decision-making app like Decisio enforces the
methodology (pairwise comparison, consistency check, eigenvector
priority) so you can't accidentally weight everything equally.
How long does a decision in Decisio take?
5–10 minutes for a typical 3-options × 4-criteria decision in
Simple Scoring mode. AHP pairwise mode adds ~3 minutes for a
typical decision (you'll do roughly 6 criterion comparisons and
~12 option comparisons). Most users save the recipe in the
Playbook and reuse it for similar future decisions.
What happens after I decide? Does Decisio track outcomes?
Yes. Each decision can be marked Right Call / Mixed / Wrong Call
weeks or months later. After 5+ rated outcomes you get a personal
Calibration Score — your decision-making accuracy percentage.
Recipes (what worked) and Principles (lessons learned) accumulate
in the Playbook so future decisions inherit your past judgment.
