Probability Lab is an interactive toolkit for exploring probability distributions and statistical concepts. Choose from a wide range of continuous and discrete probability distributions, including the Normal, Binomial, Poisson, Beta, Gamma, Student's t, Chi-Square, and many more. Instantly compute probability density (PDF), cumulative distribution (CDF), inverse CDF (quantile), and other distribution functions with precise results. Visualize every distribution using smooth, interactive graphs. Adjust parameters in real time and watch the curve update instantly, making it easy to build intuition about how each parameter affects the distribution. Whether you're studying for a statistics course, teaching probability, or simply exploring mathematical concepts, Probability Lab provides a fast, intuitive, and beautiful way to understand probability distributions. **Features** • 15+ continuous and discrete probability distributions • Compute PDF, PMF, CDF, inverse CDF (quantile), and more • Interactive graphs with real-time parameter adjustment • Smooth, high-quality visualizations • Designed for students, educators, and anyone learning probability and statistics For questions or feedback, contact us anytime at chordstudio3572@outlook.com Terms of Use https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is monetization model: Probability Lab at free against Probability Distribution's paid. Probability Lab also leads on rating (5.0 vs 4.5). Probability Distribution's advantage is ratings volume (17 vs 1) and iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Probability Distribution sells 1 one-off in-app purchase and Probability Lab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Probability Lab holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Probability Distribution has 17 ratings behind it against 1, so its average is the more settled of the two.
