Probability vs Bayes Manager
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Probability
Calculate probabilities, find percentiles, and visualize probability density or mass functions for a wide range of continuous and discrete statistical distributions. Explore common distributions like normal, binomial, Poisson, and many more.
- Compute probabilities
- Determine percentiles
- Plot probability density function
- Plot probability mass function
- Supports 10+ continuous distributions
- Supports 5+ discrete distributions

Compute probabilities, determine percentiles, and plot the probability density function for the normal (Gaussian), t, chi-square, F, exponential, gamma, beta, log-normal, Pareto, and Weibull distributions. Compute probabilities, approximate percentiles, and plot the probability mass function for the binomial, geometric, hypergeometric, Poisson, and negative binomial distributions.
Bayes Manager
This app assists managers and policymakers in calculating the likelihood of a claim or hypothesis being true. It uses Bayes' Rule and available evidence to provide probability estimates.
- Estimate claim probability
- Apply Bayes' Rule
- Utilize available evidence
- Support for managers and policymakers

The Bayes Manager app helps managers, leaders, and policymakers to estimate the probability of a claim, assumption, or hypothesis being true by applying Bayes’ Rule to the available evidence.

Verdict
The clearest difference is price: Bayes Manager at Free against Probability's $1.99. Bayes Manager also leads on iOS requirement (9.0 vs 14.0). Probability's advantage is ratings volume (193 vs 3) and chart position (#198 vs unranked). On rating, ads, in-app purchases and monetization model there is nothing between them.

Bayes Manager is free to download; Probability costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for Probability against 5.0 for Bayes Manager. That said, the two scores are not equally well evidenced: Probability has 193 ratings behind it against 3, so its average is the more settled of the two.
