Stats & Probability Calculator vs Learn While Walking

Take the frustration out of statistics and probability calculations. Whether you’re a student tackling homework or a professional analyzing data, our all-in-one Statistics Calculator app gives you fast, accurate answers in seconds. No more tedious manual math or searching for formulas – with over 140 calculators across every area of stats, you’ll have the tool you need for any problem at your fingertips. Designed for ease of use and clarity, the app is organized into intuitive categories (Probability, Distributions, Descriptive Stats, and Inference/Test calculators). Simply pick a calculator, input your data or parameters, and get instant results. Complex calculations have never been this simple! Features & Highlights: Comprehensive Toolset: Covers basic to advanced statistics – from means, medians, and standard deviations up to complex regression analyses and hypothesis tests. (140+ calculators in one app!) - Probability & Paradoxes: Calculate probabilities and odds with ease. Solve classic puzzles like Bayes’ Theorem, the Birthday paradox, Monty Hall problem, Bertrand’s paradoxes, and more. Simulate random events with a Coin Flipper, Dice Roller, or even explore lottery odds and false-positive paradoxes. - Statistical Distributions: Work with all the important distributions. Compute probabilities, critical values, and percentiles for Normal, Binomial, Poisson, Exponential, Lognormal, - - - Uniform, and other distributions. Includes tools like a Central Limit Theorem simulator and Confidence Interval calculators for population parameters. - Descriptive Statistics: Instantly get summary stats for your data set. Enter your numbers to see the mean, median, mode, range, and standard deviation (population or sample). - - View 5-number summaries (min, Q1, median, Q3, max) and identify outliers with the IQR and outlier calculators. No data set is too large – let the app do the heavy lifting in moments. - Statistical Tests: Conduct hypothesis tests without tables or tedious calculations. Our app includes t-Tests (1-sample, 2-sample, paired), Chi-Square tests (goodness-of-fit, independence), z-tests, F-tests, and even one-way ANOVA. Just input your sample data or summary stats, and get test results with test-statistics and p-values instantly. - Regression Analysis: Go beyond basic stats – perform regressions and understand relationships in data. The app features Linear Regression (with R² (R-squared) and residual analysis), as well as Polynomial and Exponential regression tools. Determine the line of best fit for your data points and make predictions without needing a complex PC program. - Charts & Plots: Visualize your data for better insights. Create histograms, box plots, dot plots, pie charts, and stem-and-leaf plots on the fly. For any data you input, the app can generate charts so you can see distribution shapes and outliers. Turn raw numbers into a visual story in one tap. - Intuitive UI & Fast Results: No learning curve required – the interface is clean and simple. Calculators are grouped by category, and each comes with clear input fields and labels. Enter your figures and get results immediately, with no internet connection needed. The app is lightweight and works offline, so you can study or work on statistics anywhere. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

The Learn While Walking iPhone app helps you practice vocabulary while you move. Simply start walking and words appear automatically after a few steps. Sessions are short, focused, and require no setup or account. The app works fully offline and uses Apple’s built-in motion system to count steps. All data stays on your device: learning progress, vocabulary, and settings are stored locally only. No analytics, no tracking, no servers. You can learn English or German in both directions, across all CEFR levels from A1 to C2. A1 is free, and each language pack includes free starter content. Additional content is available as one-time purchases — no subscriptions. Learning is based on a spaced-repetition (Leitner) approach, focusing practice where it matters most. There are no notifications, reminders, or cloud sync — just a calm, private learning experience designed for walking. iPhone only, iOS 16 or later. Open the app and start walking; the first vocabulary appears after a few steps. You can change the step threshold in Settings. On your device: steps (from iOS), learning progress and learned vocabulary, and app settings. Nothing is sent to servers. Your data stays with you.
