A statistics app either teaches statistics, with lessons and practice, or does the calculations, from mean and standard deviation to hypothesis tests and regression. The most useful ones show each step so you learn the method. Ten apps follow, in no particular order.
Statistics trips people up in two different ways. Some struggle with the arithmetic, which a calculator app fixes, while many more struggle to know which test to use and what the result means, which no calculator can fix on its own.
The apps below mix both kinds. They're listed alphabetically and in no particular order, and each description comes from the app's own App Store listing, read this week. If you'd like AI help explaining a concept, my list of copy and paste ChatGPT prompts for students has some good starting points.
Statistics apps at a glance
I checked the free plan column on each app's own App Store listing, as of Oct 2026. Yes means the page names a free plan, a free tool, a free version or a free tier. Trial only means a time-limited trial. Not stated means the page I read named neither, even where there's a try-free button, so check the provider's own page before you sign up.

Ten statistics apps worth a look
Brilliant
Best for: Learners who understand best by working through interactive problems with a tutor that sees where they go wrong.
Class Calc Graphing Calculator
Best for: Students who want statistics, graphing and matrix modes in one calculator app with no ads and nothing locked.
Inferential Statistics
Best for: Second-stage learners who want focused practice on estimation, hypothesis testing, sampling and probability models.
Introductory Statistics Tutor
Best for: Beginners who want guided lessons from describing data to hypothesis tests, with the first topic free.
IntroStat
Best for: Intro course students who'd like a probability and statistics calculator plus a built-in textbook with formulas and examples.
Khan Academy
Best for: Anyone who wants free statistics lessons and exercises from a non-profit library that also covers the rest of maths.
Statistics - StatRise
Best for: Students who revise on the move, with a calculator, study guide and AP Statistics review that work without ads or internet.
Statistics Calculator - Basics
Best for: Homework sessions where you need the mean, variance and standard deviation worked out with every step shown.
Statlio
Best for: Researchers and students unsure which test to run, since a wizard guides you to one and shows the steps in APA format.
StatPlus
Best for: Analysts and project students who need ANOVA, regression and non-parametric tests on an iPhone or iPad.

- You need ANOVA or regression: StatPlus.
- You want free lessons: Khan Academy.
The AP Statistics exam and the calculator rule
College Board says the AP Statistics exam has 42 multiple-choice questions in 1 hour 30 minutes and 4 free-response questions in 1 hour 30 minutes, with each half worth 50% of the score. That's a lot of reading and interpreting, not just number crunching.
Its calculator policy adds a detail many students miss: for the 2027 AP Statistics exams, nongraphing calculators aren't allowed, even ones with the required statistics functions. Your phone won't be in the exam room either, so practise on the graphing calculator you'll take in, and use apps to learn and check.
Learning apps versus calculator apps
- Learning apps explain ideas such as sampling, confidence intervals and p-values, with practice questions.
- Calculator apps do the arithmetic and show steps, which is ideal for checking homework.
- Analysis apps run tests such as ANOVA and regression on real data for projects.
Four questions to ask of any statistics result
- What question was the data collected to answer?
- Which test fits the type of data and the question?
- What does the result mean in plain words, not just as a number?
- What could have biased the sample?
If you can answer those four questions in a sentence each, you understand the result. If you can only quote the p-value, go back to the learning app before the exam, because exam questions ask you to explain results in context, and no calculator app will write that for you.
Do you make statistics, data analysis or maths learning apps? Tool makers can ask to be considered for a featured place on this list.
My plain advice on statistics apps
Pair one learning app with one calculator app. Use the learning app to understand which test to use and why, and the calculator to check your working, then write the conclusion in your own words, because that's the part a calculator can't do for you.
If you're taking an exam, practise on the exact calculator you'll be allowed. For more free revision help, my guide to free exam study materials lists places to start.
Frequently asked questions
What is the best statistics app?
There isn't one best app: beginners need guided lessons, while project students need an app that runs tests on real data.
Are there free statistics apps?
Yes, several apps here name free lessons, free calculators or a free tier on their listing, so check the free plan column.
Can I use a statistics app in the AP exam?
No. Phones aren't allowed, and College Board says nongraphing calculators aren't allowed for the 2027 AP Statistics exams.
How long is the AP Statistics exam?
College Board lists 42 multiple-choice questions in 1 hour 30 minutes and 4 free-response questions in 1 hour 30 minutes.
Which app helps me pick the right statistical test?
Look for an app with a test selection wizard that asks about your data and question before running anything.
Can a statistics app run ANOVA and regression?
Yes. Some analysis apps here run ANOVA, regression and non-parametric tests on an iPhone or iPad.
