Reliability Pro

Engineering calculators that name the failure mode they prevent. 28 new design-stage tools this release, spanning fluids, mechanical, electrical, thermal and materials.

Reliability Pro puts a complete reliability, quality, and engineering-design workbench in your pocket — 113 professional tools that normally live in expensive desktop software.

Run Weibull and lognormal life-data analysis; accelerated life testing (Arrhenius, Coffin-Manson, Power Law); system modeling with Reliability Block Diagrams and fault and event trees; FMEA, FMECA, and FRACAS; ANOVA, DOE, and regression; SPC control charts, process capability, Gage R&R, and acceptance sampling; Monte Carlo simulation; and live sensor diagnostics for vibration, acoustic, shock, and motion.

NEW — DESIGN FOR RELIABILITY

A category of 37 design-stage calculators, each framed by the failure mechanism it prevents rather than 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

• 113 tools across reliability, quality, statistics, engineering design, and diagnostics
• 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 analysis, and export results (PDF, text, copy)
• Methods drawn from textbook formulas and published standards, with assumptions and limitations stated in each tool

Built for speed — a problem that takes an hour on a desktop app takes seconds here.
