Notes
?
Reliability Pro is a complete reliability, quality, and design-engineering workbench in your pocket — 140+ 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
Quality & SPC — control charts, process capability, Gage R&R, 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
140+ tools spanning 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 the analysis, and export results (PDF, text, or 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. Manage or cancel anytime in your Account settings.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
This release is a big usability and analysis upgrade:
• Cleaner data entry everywhere — spreadsheet-style tables with CSV/Excel import and downloadable templates across the analysis tools, so you can see the exact column layout before you load a file.
• New Data Normalizer — reshape and rescale a column (standardize, min–max, log, Box–Cox, or unit conversion) before it goes into the stats.
• DOE Workbench — plan a full or fractional design and analyze the responses in one place, with per-factor variable levels.
• Gage R&R Workbench — plan the study, then validate the measured data in one flow.
• Graph Builder — new group/color-by, box plots, histograms, and a scatter fit line with R².
• New Paris' Law crack-growth tool.
• Redesigned Confidence Interval with a raw-data / summary-stats toggle.
• Reorganized statistics into Basic and Advanced sections for easier navigation.
• Faster, more reliable startup and general stability fixes.
Thanks for the feedback — keep it coming.
