Skinnify

By far the best A/B testing app on Shopify. The analytics are excellent, and it costs about half as much as similar apps.

By far best app for a/b testing. We are testing everything and we are paying less than other apps and get so much more. Definitely recommend.

This is my first time using Impact, so I am not sure about its long-term effects on us; however, so far it has been going well. Their support team is also very responsive.

Great! The customer support team is always helpful with our issues.
