PROKRINO · NATIVE FOR iPHONE, iPAD AND MAC
Make complex choices feel clear.
Compare options, weigh what truly matters and test how robust the result is before you decide.
Compare. Weigh. Decide.
Why Prokrino
Turn every complex choice into a decision you can defend.
Think in structure
Turn a difficult choice into a clear goal, meaningful criteria and comparable options.
See why one option leads
Rankings, weights, consistency and reasoning make the result understandable and defensible.
Test what could change the answer
Sensitivity, scenarios and 1,000 local simulations reveal whether the leading option is robust or fragile.
Document the process
Create a professional report with ranking, uncertainty, reasoning and outcome review.
Decide together, without groupthink
Combine up to 100 independent responses and see exactly where the group agrees or differs.
Learn from the real outcome
Compare your original confidence and assumptions with what actually happened.
How it works
From “where do I even start” to a decision with a record.
-
01
Structure the choice
Define a clear goal, the criteria and the real options. Smart Start suggests a template, workflow and effort estimate from three short questions.
-
02
Weigh what matters
Compare criteria in pairs on the 1–9 scale and use numeric measurements where real data exists.
-
03
Evaluate the options
Each criterion can be a qualitative judgment, higher-is-better or lower-is-better.
-
04
Check the quality
Consistency, completeness, documentation and Decision Readiness show how ready the decision is.
-
05
Stress-test it
Sensitivity, what-if scenarios and Monte Carlo show whether the leading option holds when uncertain judgments plausibly change.
-
06
Record and learn
Note what you chose, with what confidence and which assumptions — then compare with what actually happened.
Inside the app
Explainable results
A full ranking, criteria weights and a Consistency Ratio — you see what drives the decision, not just who “won”.
Uncertainty lab
1,000 deterministic Monte Carlo simulations run on-device and show whether the ranking is strong, moderate or fragile. The “first-place frequency” measures how robust the ranking is to your recorded uncertainties — not the probability of real-world success.
What-if scenarios
Adjust priorities with sliders, save scenarios and see when the winner changes.
Professional PDFs
Executive summary, ranking, weights, a judgment audit trail and outcome review — with organization, client and logo details in Pro.
Facilitator Mode
Up to 100 independent responses per session, with no accounts for participants. Invitations and responses are exchanged privately as files through the app — asynchronous, not real-time collaboration.
Decision Journal
Record the final choice, your confidence and your assumptions — and set a review date. Pro adds portfolio analytics: confidence calibration, over- and under-confidence patterns, a decision ledger and an annual Decision Review PDF.
19 starting points
18 ready-made frameworks plus a blank decision: from choosing a home, a car or a laptop to supplier selection, hiring, project prioritization, budget allocation and ERP/CRM selection. Pro users can save their own reusable templates.
Keep the decision yours.
Prokrino is local-first and performs its analysis on-device. It requires no Afterwork Studio account, contains no ads or tracking, and shares only what you choose to export.

Frequently asked questions
What is Prokrino?
A native app for iPhone, iPad and Mac that helps you structure complex decisions, compare options consistently and test how robust the result is.
Do I need to know AHP?
No. Smart Start, the templates and the guided flow explain every step. The method stays visible for anyone who wants to inspect the details.
Is it free?
You can complete one full personal decision for free. Pro unlocks unlimited decisions and the advanced features with a single one-time purchase — no subscription.
Does the app decide for me?
No. It organizes your own priorities and evidence, reveals contradictions and uncertainties and presents an explainable recommendation. The final decision stays yours.
Does it use AI?
Not for producing the recommendation. The calculations are based on AHP and deterministic robustness analysis, so the result is repeatable and explainable.
Are my decisions private?
Yes — they are stored locally by default. No Afterwork Studio account is required and there are no ads or tracking. You choose what to export or share.
Can a team use it?
Yes. A facilitator with Pro can invite up to 100 people. Participants answer independently, with no purchase or account, inside the app, and return a private response file.
Is there a subscription?
No. Pro is a one-time purchase.
Which devices does it run on?
iPhone and iPad with iOS/iPadOS 18 or later, and Mac with macOS 15 or later.
For choices that deserve more than intuition.
