It's a great start, but it'd be better if you could add multiple variants

Having my calculator right there all the time makes it so easy to monitor test results, no matter what tool I'm using for testing.

This tool is a blessing! Makes it easy as pie to quickly determine A/B test winners and drive critical CRO decisions. Best of all, it sits right inside your browser so it's always just a click of a button away.

Incredibly simple. You just enter the numbers and boom, it tells you if it is significant or not. Saves me time from having to goto a website to run the same calculation. Clean, simple, quick...its just what I need.

This tool has prevented me from making a ton of bad calls on AB tests and Marketing Metrics. It has never been easier to check the Statistical Significance of my data.
