Uncertia: Measurement Budget

iOS app by Shadowfetch · App Store ID 6792422099 · iOS

Uncertia is a private measurement-uncertainty budget studio for calibration technicians, metrologists, quality engineers, laboratories, educators, and technical teams that need more transparency than a copied spreadsheet formula.

Define the measurand and result, then add Type A and Type B contributors with half-width, distribution, sensitivity coefficient, evidence, and degrees of freedom. Uncertia converts each row to standard uncertainty, combines independent variance, ranks contribution, estimates effective degrees of freedom, and reports expanded uncertainty at the selected coverage factor.

Key Features

• Type A and Type B contributor ledger
• Standard, rectangular, triangular, and normal-95% conversions
• Visible divisor and sensitivity coefficient
• Combined standard and expanded uncertainty
• Variance contribution chart
• Welch-Satterthwaite effective degrees of freedom
• Editable measurand, units, result, and coverage factor
• Local uncertainty-budget PDF
• 300 original offline technical plates
• No account, ads, analytics, tracking, IAP, or subscription

Uncertia supports transparent GUM-style calculations and audit discussion. Confirm the measurement model, dependence and covariance, source distributions, divisors, sensitivity coefficients, degrees of freedom, traceability, and reporting rules with your laboratory procedure.
