Reliability Pro is a complete reliability, quality, and design-engineering workbench in your pocket — 165+ professional tools that normally live in expensive desktop software, ready in seconds. A problem that takes an hour on a desktop takes seconds here. CORE CAPABILITIES Life data analysis — Weibull and lognormal fitting, censoring, confidence bounds Accelerated life testing — Arrhenius, Coffin-Manson, and Power Law System modeling — reliability block diagrams, fault trees, and event trees Failure analysis — FMEA, FMECA, and FRACAS Statistics & DOE — ANOVA, regression, and a side-by-side plan-and-analyze DOE workbench Quality & SPC — control charts, process capability, Gage R&R, acceptance sampling Monte Carlo simulation Live sensor diagnostics — vibration, acoustic, shock, and motion NEW — RELIABILITY-CENTERED MAINTENANCE Decide what maintenance each failure mode needs, then set the interval: RCM Decision Worksheet — consequence and task-selection logic after SAE JA1011 Optimal Replacement Interval — the lowest-cost replacement age from Weibull data P-F Interval Planner — how often to inspect for condition monitoring Failure-Finding Interval — test intervals for relief valves, trips, and alarms Maintenance Strategy Comparison — run-to-failure vs time-based vs condition-based 2D FIELD SOLVERS Screen a real design, not just a formula — physics-of-failure solvers that feed a life model: Thermal CFD — board hot spots under airflow Thermal Cycling — solder-joint fatigue Moisture Ingress — popcorn-cracking risk Current-Density Field — electromigration from current crowding Enclosure Convection, Forced-Air Cooling, and Liquid Cold-Plate Galvanic Corrosion — penetration rate for dissimilar-metal joints DESIGN FOR RELIABILITY 45+ design-stage calculators, each framed by the failure mechanism it prevents: Fluids & flow — pressure drop, NPSH, valve sizing, water hammer, flow-induced vibration, two-phase flow Mechanical & structural — bolted joints, beam deflection, column buckling, Mohr's circle, tolerance stack-up Electrical & PCB — trace width, voltage drop, RC/RLC damping, battery runtime, creepage and clearance, derating Thermal — junction temperature, heat sinks, transient response, heat exchangers, fin efficiency, dew point Chemical & materials — corrosion rate, galvanic compatibility, MSL floor life Optical & photonics — fibre link budget, LED lumen maintenance, illuminance SEMICONDUCTOR RELIABILITY Electromigration, gate-oxide TDDB, BTI/HCI, die-attach and flip-chip fatigue, wirebonds, popcorn cracking, HTOL FIT, and acceleration factors WHO IT'S FOR Reliability, quality, maintenance, and design engineers; Six Sigma practitioners; students; and anyone who needs trustworthy results fast. WHAT YOU GET Every tool opens with a realistic example dataset Compare candidate models ranked by R² and AICc in curve fitting, degradation, and life-data analysis Basic Statistics tools are free for everyone; try any premium tool 5 times before signing in AI assistant and search to jump to the right tool Step-by-step video tutorials A reference library with theory, worked examples, key equations, and citations for every tool Import data and export a professional PDF report with theory, equations, a worked example, results, charts, and references Methods drawn from textbook formulas and published standards, with assumptions stated in every tool Missing a tool?
