Apex for Shopify
A/B testing for Shopify, with the odds up front
For more revenue from the traffic you already pay for.
Install the app, switch it on in your theme, and every test idea gets its Likelihood to Win before you build it.
30 days free. No card. Then the free plan, nothing to cancel.
How it works
From install to your first scored idea
Install the Apex app
Install it via the link you get after sign-up. Server-side tracking and first-party data come with it.
Switch it on in your theme
Turn on the Apex app embed in the theme editor. It runs your tests on the storefront and works with most consent apps.
Your first idea, scored
Add an idea. It gets its Likelihood to Win and its place in your backlog, before anyone builds it.
SNOCKS runs on Apex
Since October the whole SNOCKS group runs its tests on snocks.com in Apex. Before that came over 550 experiments with DRIP. This is what testing brought SNOCKS:
“They supported us every step of the way, from underdogs to market leaders. Their expertise helped us stay profitable, giving us the foundation to scale and dominate our market.”

The whole testing program, with profit per test on Shopify
Likelihood to Win
Every idea gets one number before you build it, with the tests behind it, so the backlog sorts itself.
The score ranks an idea against your own backlog; it is not a win probability in the strict sense.
Profit per test and heat maps
On Shopify, see what a variant earns after discounts and refunds, not only revenue. Next to it, clicks, scroll depth and funnel steps for each variant.

Pauses a test when a variation gets no conversions while the original converts, or clearly converts worse.
Apex in ChatGPT or Claude
Connect Apex once, then build and read tests from the chat. No terminal; developers have the CLI.
Parallel tests
Several tests on the same traffic, with exclusion groups when two tests should not meet.
Thanks to DRIP, our team now thinks in tests and data.
