StatsPL Sims is a collection of easy-to-use, interactive simulations to explore statistics. StatsPL Sims was developed for College students taking an Intro to Stats (Stats 101) course, but is also suitable for high school students taking statistics. The following simulations are currently included: -Simple Random Sampling -Frequency Tables vs. Histograms -Histogram Explorer -Central Limit Theorem -Dice Roller -Confidence Intervals -Regression Line Game -Regression Line Explorer -Correlation Coefficient (R) -Normal Distribution -Binomial Distribution -Chi Square Distribution -F Distribution -T Distribution Over the next months, we will add more simulations on additional topics, such as: -One-sample t-test -Two-Sample t-test
Probability Distribution
This app allows users to calculate probabilities and visualize various continuous and discrete probability distributions. It supports a wide range of common distributions and plans to add more in the future.
- Calculate probabilities
- Visualize distributions
- Normal (Gaussian) distribution
- Binomial distribution
- Poisson distribution
- Exponential distribution

Verdict
The clearest difference is in-app purchases: StatsSims at none against Probability Distribution's 1. StatsSims also leads on review sentiment (50% vs 33%) and iOS requirement (6.0 vs 16.0). Probability Distribution's advantage is rating (4.5 vs 4.2) and update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. Probability Distribution sells 1 one-off in-app purchase. StatsSims asks for nothing beyond the download.
Probability Distribution holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 5 and 15 respectively. Written reviews complicate that: 50% of StatsSims's written reviews are positive against 33% of Probability Distribution's, so the app with the better star average is not the one people write more warmly about.
StatsSims ships an update every 2 months, Probability Distribution every 2 weeks. The most recent releases landed on June 11, 2026 and September 9, 2026 respectively.
