## Description

Plan A/B tests with confidence: find the sample size you need, then check whether your winner is statistically significant — confidence intervals included.

A/B Testing Calculator helps you plan and evaluate A/B tests: work out how many users you need for a reliable result, and find the test winner with statistical significance in mind.

BEFORE THE TEST — SAMPLE SIZE
Set your baseline rate, expected uplift, reliability and power — and the app calculates how many people should see each variant. Works for open rate, click rate and order conversion.

AFTER THE TEST — RESULTS
Enter the number of conversions and the sample size for each variant (up to 5) — the app shows conversion rates, confidence intervals and a clear verdict: which variant is better and whether you can trust the result.

FEATURES
• Two calculators: sample size and results evaluation
• Compare up to 5 variants at once
• Confidence intervals and statistical-significance testing
• Clear explanations without statistical jargon
• Copy any result with one tap

Great for marketers, product managers and analysts.
