The Bayesian P-Value Interpreter is used to calculate the probability of outcomes in clinical trials by interpreting reported p-values in the context of scientific expectations and prior probabilities, employing Bayesian thinking. ### How does the Bayesian P-Value Interpreter help with p-value interpretation? It aids in the realistic interpretation of reported p-values by referencing prior knowledge of the probability of an experimental outcome. This approach helps to avoid common misinterpretations of p-values. ### Does the Bayesian P-Value Interpreter require prior knowledge of Bayesian statistics? While it employs Bayesian inference, the app includes 'Learn more' buttons that provide explanations of prior probabilities, p-values, and Bayesian probabilities, illustrated with examples to help users understand the concepts. ### What kind of trials can be analyzed with the Bayesian P-Value Interpreter? The app permits realistic interpretation of reported p-values from user-entered pre-trial probabilities for both single and sequential trials. ### Is the Bayesian P-Value Interpreter available on multiple devices? Currently, the Bayesian P-Value Interpreter is supported on iPhones. Information regarding availability on other devices is not provided. ### How often is the Bayesian P-Value Interpreter updated? The latest version is 2.3, and it was last updated on May 26, 2026. This indicates a recent update, suggesting ongoing development and maintenance. ### What is the user sentiment for the Bayesian P-Value Interpreter? The app has a perfect rating of 5.0 stars from 3 ratings, indicating very positive user sentiment among its current users. ### Does the Bayesian P-Value Interpreter have ads? No, the Bayesian P-Value Interpreter does not contain advertisements. It is a free application without any ad interruptions. ## Version history (last 5 releases) ### 2.5 — 2026-06-19 Prior Sensitivity Analysis! • Not sure about your prior? A new Sensitivity panel instantly shows the posterior across a range of priors centered on your input, so you can see at a glance how much your starting assumption matters. Deeper sequential workflows! • Select any row from the Sensitivity table and continue directly into a Sequential Analysis starting from that scenario, no manual copying of numbers. • A new Probability Summary chart now displays four bars — your original prior, the first posterior, the discounted prior used for the sequential analysis, and the final posterior — so you can see exactly how the evidence and your discounting choices shape each step. Progressive "Add Analysis" layout! • The calculator now builds up on demand. Run your main calculation, then add a Sensitivity or Sequential panel only when you need it, keeping the screen clean for straightforward cases. New app icon! UI/UX polish and bug fixes! (again) • Tightened spacing and typography across the calculator, settings, and summary chart. • Smoother transitions when adding or removing analysis panels. • Improved overall navigation flow and fixed a highlight bug in the Sensitivity table. ### 2.3 — 2026-05-26 Prior Sensitivity Analysis! • Not sure about your prior? A new Sensitivity panel instantly shows the posterior across a range of priors centered on your input, so you can see at a glance how much your starting assumption matters. Deeper sequential workflows! • Select any row from the Sensitivity table and continue directly into a Sequential Analysis starting from that scenario, no manual copying of numbers. • A new Probability Summary chart tracks how evidence accumulates across both studies. Progressive "Add Analysis" layout! • The calculator now builds up on demand. Run your main calculation, then add a Sensitivity or Sequential panel only when you need it, keeping the screen clean for straightforward cases. New app icon! Bug fixes!(again) • Improved UX flow and fixed a highlight bug in the sensitivity table. ### 2.0 — 2026-03-31 • Completely redesigned with a clean, modern interface • Interactive gauge visualization shows how evidence updates your beliefs • Built-in guided tour walks you through Bayesian p-value interpretation step by step • Sequential analysis: chain multiple studies together with adjustable discount factors • Real-time updates — the gauge and charts animate live as you adjust the discount slider • Comprehensive Learn More articles with worked examples • Contextual tooltips on every input field • Adjustable font scaling for accessibility • Light and dark mode support ### 1.1 — 2026-03-09 New and improved Explanations! ### 1.0 — 2026-02-06 No release notes. ## Apps similar to Bayesian P | App | Rating | Price | Category | | --- | --- | --- | --- | | [LinearSolver](https://appshunter.io/ios/app/linearsolver/id895469797) | 3.0 (1) | $1.99 | Education | | [Statistics AI: Solve it](https://appshunter.io/ios/app/statistics-ai-solve-it/id6758206200) | — | Free | Education | | [The Base Converter](https://appshunter.io/ios/app/the-base-converter/id6743086704) | — | Free | Education | | [NIAID Stats Calculator](https://appshunter.io/ios/app/niaid-stats-calculator/id6738212796) | — | Free | Education | | [Statistics & Probability Tutor](https://appshunter.io/ios/app/statistics-and-probability-tutor/id6767269528) | — | Free | Education | | [Formulae Pro](https://appshunter.io/ios/app/formulae-pro/id1666691016) | — | $1.99 | Education | ## Related topics [bayes](https://appshunter.io/ios/topics/bayes) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
