About this app

Arbor is a professional decision tree builder designed for anyone who needs to think clearly under uncertainty — lawyers, strategists, product managers, investors, and curious minds alike.

Map out complex decisions as structured trees. Assign a probability to each branch. Arbor instantly calculates your expected outcome score and tells you exactly where your weakest links are.

──── FEATURES ────

🌿 Visual Decision Tree
Build unlimited nodes, connect them into multi-level trees, and watch your decision model take shape in real time.

📊 Live Outcome Score
Every node you add updates the expected outcome score instantly — colour-coded STRONG / MODERATE / WEAK so you always know where you stand.

🔍 Insights Tab
Automatic bottleneck detection, probability distribution charts, and AI-style recommendations highlight exactly what to improve.

⚡ Scenario Simulator
Run Optimistic, Realistic, Base, and Pessimistic scenarios in one tap. Sensitivity analysis shows which single node would move the needle most.

📋 Summary View
A full-page model health report with arc indicator, depth stats, orphan warnings, and per-node notes.

🌙 Dark & Light Mode
Toggle between a deep space dark theme and a crisp periwinkle light theme — instantly, from the toolbar.

🔒 100% Offline & Private
No account. No network. No data collection. Everything lives in your device's memory. Zero permissions required.
