Reliability Pro

Reliability & Quality toolkit

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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. 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. Manage or cancel anytime in your Account settings.

Design for Reliability — a new category of 28 engineering design calculators. Rather than generic engineering maths, each tool is built around the failure mechanism it prevents, so the output tells you what will break and why: FLUIDS & FLOW Pipe pressure drop, NPSH margin, valve Cv, tank drain, plus new flow-induced failure screening — water hammer surge, acoustic-induced vibration, vortex shedding lock-in, two-phase slug loading and 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. THERMAL Transient thermal response, heat exchanger sizing, fin efficiency — now alongside the existing thermal and derating tools in a single place. CHEMICAL & MATERIALS Corrosion rate, galvanic compatibility, MSL floor life. OPTICAL & PHOTONICS Fibre link budget, LED lumen maintenance, illuminance design. ALSO IN THIS RELEASE - Discover expanded with theory, key equations, worked examples and references for every new tool - Categories reorganised so nothing appears in two places - Tool naming clarified to reflect what each one actually measures - Assorted fixes and performance improvements
