New: Reliability-Centered Maintenance section - RCM Decision Worksheet (SAE JA1011) - Optimal Replacement Interval, P-F Interval Planner, Failure-Finding Interval, Maintenance Strategy Comparison Also new - Weibull Shape Explorer, CI vs Sample Size, Permutations & Combinations - Send feedback or suggest a tool from any screen - Try each tool free 5 times before signing in Fixes and improvements.

This update focuses on reports and consistency across the app: - Charts and diagrams now appear in exported PDF reports — thermal, semiconductor, and design-for-reliability tools included. - Every tool now shares one clean, professional report layout: theory and background, key equations, a worked example, and references. - Worked examples now reflect the values you enter, so the example matches your actual analysis. - One-tap PDF export is now available on every tool. - New reference guides added for quality methods: House of Quality (QFD), Kano Model, Pugh Concept Selection, SIPOC, Taguchi Loss Function, Attribute Agreement Analysis, and OEE. - Stability improvements and interface polish throughout. Thanks for using Reliability Pro. Questions or requests? We'd love your feedback.

This update makes the analysis tools faster to use and easier to learn, with worked examples built in. Degradation Analysis - Pick your own fit model from a ranked list showing R² and AICc — the same workflow as Fit Nonlinear Curves — instead of relying on a single auto choice. - New example: 3 samples, each following a different trend (linear, exponential, mechanistic growth), so you can see every model at work. - Clearer time-to-failure projection against a failure limit. Life Data - Weibull and Lognormal Solvers now open with full 20-point example datasets. - The Lognormal Solver uses the same side-by-side inputs/results layout as the Weibull Solver. DOE & Measurement Systems - DOE Workbench and Gage R&R redesigned into a side-by-side Plan | Analyze view on larger screens, each preloaded with a clean example dataset. Statistics - Distribution Analyzer simplified to a single data column. - Advanced Statistics reorganized — Graph Builder and Time Series moved to the end of the list. General - More calculators return results instantly as you type. - Smoother, full-width layouts that scale with your screen. Thanks for using Reliability Pro. Have a request?

Minor UI improvements plus new quality tools.

Minor UI improvements

- Professional PDF reports: export any tool as a polished engineering report — theory, key equations, a worked example using your own data, results, charts, and references. - Fixed garbled math symbols in exported and printed reports. - Basic Statistics tools are now free for everyone (Confidence & Tolerance Intervals, Normality Tester, Data Normalizer, Probability Stats, Graph Builder, Time Series). - New data normalization (Log, Ln, √, Box–Cox) in the interval and normality tools. - Try premium tools with a free preview before signing in. - Stability and performance improvements.

- Try before you sign in — preview every premium tool once, free. - Basic Statistics is now free for everyone: Confidence & Tolerance Intervals, Normality Tester, Data Normalizer, Probability Stats, Graph Builder, Time Series. - New data normalization (Log, Ln, √, Box–Cox) built into the interval and normality tools. - Confidence Interval now opens in raw-data entry mode. - Save, open and share your project files. - Stability and performance improvements.

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.

NEW — 2D field solvers in Design for Reliability. Each maps a failure mechanism and links it straight to a life model: • Moisture Ingress — how moisture diffuses into a package and when popcorn-cracking risk crosses the line • Thermal Cycling Field — solder-joint fatigue from the temperature swing a board sees • Current-Density Field — electromigration from current crowding at a neck or void • Enclosure Convection — how heat pools in a sealed chassis • Forced-Air Cooling — where airflow reaches, and the dead zones it misses • Galvanic Corrosion — penetration rate and time-to-perforate for dissimilar-metal joints • Liquid Cold-Plate — coolant outlet rise, peak junction temperature and thermal resistance Each includes an interactive field view, a pass/caution/fail verdict, a bridge into a reliability model, and a PDF report — plus a matching theory card with equations and references. Also in this release: stability improvements across the simulation tools so extreme inputs always produce sensible, bounded results.

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

Reliability Pro is now built for iPad! - Full iPad support with a split-view layout — browse the tool library on the left while you work on the right - Keep up to 4 tools open at once and switch instantly without losing your inputs - New quick launcher with your favorites and recently used tools - Discover tab redesigned for iPad: browse references alongside full theory, equations, and further reading - Tools reorganized into clearer categories for faster navigation - Full mouse and trackpad support for Magic Keyboard users - All orientations and Split View multitasking supported Plus performance improvements and fixes throughout.

Added a new Light Diagnostics suite: • Light Meter — compare brightness between two spots using your camera, with a reference-capture baseline for accurate comparisons • Strobe / Light Source — a steady inspection light or adjustable strobe, handy for eyeballing shaft/fan rotational speed • Light Spectrum — estimates the color temperature (CCT) of ambient or indicator lighting Added optional App Lock — secure the app with Face ID, Touch ID, or your device passcode, on top of your existing sign-in. Also expanded the in-app reference library with additional technical guides.

• Added a confirmation prompt when signing out, to prevent accidental logouts. • Light and dark theme switching is now instant. • Stability and performance improvements.

Acoustic Diagnostics now requests microphone access reliably so live capture works on first use. Tool lists now clearly mark which tools are PRO and which are FREE, including after a trial ends. Stability improvements.
