RAlN-B Official is a structured thinking tool designed to help you make complex decisions with clarity and confidence. Instead of relying on gut feeling or scattered notes, the app guides you through a proven multi-criteria analysis process. Define your decision, add 2–6 options, choose the criteria that matter most, and assign importance weights that total 100%. Then score each option and instantly see a ranked outcome supported by clear visuals and numeric transparency. Interactive charts reveal strengths and weaknesses at a glance, while automatic summaries highlight what is truly driving the result. Go beyond static scoring with Sensitivity Analysis, which lets you adjust one factor at a time to see how rankings shift in real time. The Stability screen measures how robust your decision is and identifies the tipping points that could flip the outcome. Save multiple scenarios, compare them side-by-side, and revisit past decisions with full history tracking. Built-in templates for vendor selection, hiring, product comparison, investment choices, and major purchases help you get started quickly, while blank mode gives you full flexibility. RAlN-B Official does not tell you what to choose — it helps you understand why a choice makes sense. Designed for professionals, students, and thoughtful individuals, it turns uncertainty into structured insight and makes your reasoning defensible, repeatable, and transparent. ## Key features - Multi-criteria analysis process - Define decision, options, and criteria - Assign importance weights - Score options for ranked outcomes - Interactive charts and summaries - Sensitivity analysis - Stability analysis ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Upgrade to Premium | $0.99 | one-time | ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/raln-b-official/id6759346913/reviews.md ### 1/5 — FAKE APP DO NOT DOWNLOAD *2026-05-17* I tried withdrawal money but it didn’t seem to work only to realize this is NOT the official rainbet app, there is no real rainbet app and it can only be accessed through their website ### 5/5 — Smooth login *2026-05-09* Everything runs smoothly and consistently.
