A/B testing statistics done right

A/B testing calculator

Smart and rigorous statistics are often the missing driver of success for CRO & UX teams.

Free online tools are too simple, inefficient, and invite malpractice. Many others appear statistically sound yet make compromises with the very essence of what that means. Claims of tests optimal for your business are made while failing to take any business metrics as input.

The A/B testing hub changes all that and helps you make the most of your online A/B tests.
