Reliability Pro is a complete reliability, quality, and design-engineering workbench in your pocket — 150+ 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 design of experiments in a side-by-side plan-and-analyze workbench Quality & SPC — control charts, process capability, Gage R&R (guided plan-and-validate), acceptance sampling Monte Carlo simulation Live sensor diagnostics — vibration, acoustic, shock, and motion NEW — 2D FIELD SOLVERS Screen a real design, not just a formula. Interactive physics-of-failure solvers that map the field and carry the result straight into a life model: Thermal CFD — the hot spot on a board under airflow Thermal Cycling — solder-joint fatigue from the temperature swing Moisture Ingress — popcorn-cracking risk over floor time Current-Density Field — electromigration from current crowding Enclosure Convection — hot pockets in a sealed box Forced-Air Cooling — airflow dead zones on a board Liquid Cold-Plate — junction temperature and coolant rise Galvanic Corrosion — penetration rate for dissimilar-metal joints DESIGN FOR RELIABILITY 37 design-stage calculators, each framed by the failure mechanism it prevents — not just the equation it solves: Fluids & flow — pipe pressure drop, NPSH margin and cavitation, valve sizing, water-hammer surge, acoustic-induced vibration, vortex shedding, two-phase slug loading, parallel flow distribution Mechanical & structural — bolted-joint preload, beam deflection, column buckling, Mohr's circle, tolerance stack-up Electrical & PCB — trace width, wire voltage drop, RC/RLC damping, battery runtime, creepage and clearance, component derating Thermal — junction temperature, heat-sink sizing, 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 design WHO IT'S FOR Reliability, quality, maintenance, and design engineers; Six Sigma practitioners; students; and anyone who needs trustworthy results fast. WHAT YOU GET 150+ tools spanning reliability, quality, statistics, engineering design, and diagnostics Every tool opens with a realistic example dataset — see it work before entering your own Compare candidate models side by side, ranked by R² and AICc, and pick the fit you trust — in curve fitting, degradation, and life-data analysis Basic Statistics tools are free for everyone; preview any premium tool once before signing in A built-in AI assistant and search to jump straight 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, run the analysis, and export a professional engineering report — a polished PDF with theory, key equations, a worked example, results, charts, and references — or plain text/copy Methods drawn from textbook formulas and published standards, with assumptions and limitations stated in every tool SUBSCRIPTION Full access to all tools is available via an auto-renewing subscription (monthly or annual). Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically unless cancelled at least 24 hours before the end of the current period.
