Riskquarry: Delivery Odds

Monte Carlo Project Forecast

$1.99 · Designed for iPad. Not verified for macOS.

Replace a single project date with deterministic Monte Carlo percentiles, task-level uncertainty, sensitivity, ownership, and planning evidence. Riskquarry is a local probabilistic delivery workbench for technical leads, consultants, independent developers, operations teams, and project owners who need honest schedule ranges without moving plans into another cloud. Run thousands of seeded task-duration scenarios and plan around a chosen confidence percentile rather than a single optimistic sum. KEY FEATURES - Seeded deterministic Monte Carlo engine - P50, P80, and P95 delivery range - Optimistic, likely, pessimistic tasks - Task uncertainty risk screen - Assumption and owner register - 10,000-run export forecast - Decision and contingency log - Fully local project data - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - 48 original offline technical reference plates - No account, ads, analytics, tracking, IAP, or subscription Riskquarry simulates entered triangular task estimates and does not predict the future. Dependencies, correlation, scope changes, staffing, queues, interruptions, quality, and unknown work can dominate the result. Revisit assumptions with the people doing the work and communicate ranges, not guarantees.
