About this app

MAJOR SEPTEMBER 2026 UPDATE

ShinStats has been extensively redesigned and expanded.

More calculators. Better test guidance. Clearer step-by-step solutions. Improved navigation. A refined experience built to help students understand statistics and probability from start to finish.

Statistics homework giving you trouble? ShinStats is a step-by-step statistics solver built for students.

Enter the information from your problem and follow the complete solution, not just the final answer. Study for exams, check your homework, and learn offline with equations, substitutions, statistical tables, graphs, and fully worked calculations.

WHY SHINSTATS?

ShinStats works like a patient statistics tutor in your pocket. Enter your values and follow the calculation from setup to result.

See formulas, substituted values, intermediate steps, critical values, p-values, statistical tables, and graphs whenever the method requires them.

BUILT FOR STUDENTS

Use ShinStats for high-school and college statistics homework, assignments, practice problems, quizzes, and exam preparation.

The app is designed to show how each solution is obtained so you can understand the process and follow the same method by hand.

SEE THE WORK, NOT JUST THE ANSWER

ShinStats is built around transparent, worked solutions.

When a problem requires a statistical table, graph, critical value, or intermediate calculation, the app shows the relevant steps instead of hiding the method behind a single result.

FIND THE RIGHT CALCULATOR

Not sure which statistical method you need? ShinStats includes guidance to help you identify the appropriate calculator for your problem and get to the right tool faster.

WORKS OFFLINE

No internet connection is required for supported calculations. Work through statistics and probability problems in class, while commuting, or anywhere you want to study without depending on a connection.

LEARN THE METHOD. CHECK THE RESULT.

Whether you're checking homework, preparing for an exam, practicing statistics, or learning a new statistical method, ShinStats gives you a structured path from the information in the problem to the completed solution.

Download ShinStats and work through your next statistics or probability problem step by step.

What’s new

What's new in it compared with v2.30:
- Fill check: while the scan runs, Auto fills each recommended calculator. The ones your numbers fill completely go first, and a single clear winner becomes "Yes, that matches". Picking a recommendation opens straight away.
- Rank-based tests: Kruskal-Wallis, Mann-Whitney and Wilcoxon now open with the lists filled instead of empty.
