More details about Theme Scientist A/B Testing

Product description

Theme Scientist offers a service for Shopify store owners to boost conversion rate by A/B testing changes to store themes or product details. The service provides data for store optimization, improves sales and includes a scheduler for timed updates, offering greater control over customer experience.

AI summary

This Shopify app specializes in A/B testing and theme scheduling, enabling merchants to compare different versions of their store themes or product features to optimize performance. Its core functionality includes alternating themes at scheduled intervals, tracking key metrics like views, add-to-cart rates, and conversions, and providing statistical insights to determine winning variations. The app is praised for its intuitive interface, flexibility in testing variables like pricing or design elements, and its ability to improve conversion rates. Support is generally responsive, with developers actively incorporating user feedback into updates. However, some limitations include occasional inaccuracies in test metrics, delayed or inconsistent customer support responses, and technical restrictions imposed by Shopify that prevent live visitor splitting. Additionally, uneven time allocation for theme swaps is not currently supported, which may skew test results. Despite these drawbacks, the app is widely regarded as a powerful tool for data-driven decision-making, particularly for merchants committed to continuous optimization.

★★★★★Jeans4you.shopfrom United States · 8 March 2025

It is an excellent app for future time scheduling.

★★★★★Elizabettafrom United States · 12 August 2024

This is a very useful app, and it's free! Helpful support staff, easy to use, I'm very happy.

★★★★★Ministry of Scentfrom United States · 22 August 2022

This app is easily one of our favorites and most used tools. We've used it to test multiple growth ideas and increase our revenue by over $50k a year so far. Developers are responsive, kind and very helpful. They've even introduced me to other products and people that could have been a better option for us. We want to test store-wide features so we create 2 versions of the same theme, and every 24 hours the theme switches. It's obviously more ideal to split visitors live, but Shopify seems to restrict developers from creating this experience. Everyone on our team is always really excited about our tests and results. My 2 requests would be to add slightly more robust insights on the results table and to be able to split audiences live (fingers crossed one day shopify will let it be built!)

★★★★★Haltungshelferfrom Germany · 1 February 2022

I really like the interface and i am nearly fully happy! BUT i would like to set the swapping times to something uneven, like 1/3/5/7/9 hours in order to really give every option the same time frames during a day.If i put my A/B test to swap every 4 hours for example, A would get 8-12 and 16-20 o clock every single day, which would mix up by swapping them every 3 hours. I would love, that you update this feature in the near future and ill happily give you 5 stars Great job guys! Love the update! Cheers :)

★★★★★Lift Downfrom United States · 13 December 2021

    This is a beautiful app! Don't let the currently small number of reviews turn you off. It's ease of use, simplicity, and effectiveness are top notch. It works like an absolute charm. And apparently - the dev crew is fantastic also, that's why I'm writing this review, I casually mentioned a feature I thought would be good, and wouldn't ya just know it, they said they will add it in - and quite soon even. Yea, for AB testing, it's rad.Theme testing and product testing with price testing also. It's legit awesome.

    Don't let the lack of reviews for Theme Scientist scare you away. We actually tried them all, and were ready to give up when we took a shot on TS with no reviews. Wow, intuitive, exactly the type of tests we were looking for, and unlike some of the others, it never broke themes while testing. We are actually in the ABT mode (Always Be Testing) now for life now, and this App has already given us the insights to double, yes double our conversion rates in 3 months. Word of wisdom, small tests, and keep variables isolated, so you know what is moving the needle. Last but not least, Joe, the man behind the curtain is an absolute Rockstar. Like us, always putting the customer first, and genuinely concerned about us maximizing our value from the app. Fantastic product, fantastic company, fantastic customer service!

About ShopDigest

The Shopify ecosystem, shown through the work

ShopDigest is an independent directory of Shopify work. Developers, agencies and experts publish the projects they’ve actually shipped — migrations, rebuilds, custom apps, headless storefronts — with the results attached.

For merchants, that means judging a partner on evidence instead of a sales page: browse real builds in your category and budget, then reach out directly. For builders, it means one profile that keeps working after the project ships.

No commissions, no pay-to-rank placements. The best work rises because people save and follow it.
