About Theme Scientist A/B Tester
A/B testing is key to maximizing your conversion rate.
Theme Scientist is an easy to use A/B testing app for Shopify.
New for 2021
We're dedicated to providing the best A/B testing tool on Shopify and have already added new features this year. We take requests and build features for you.
Increase sales without buying more traffic
Improving conversion rate maximizes the value on your website traffic. A single successful experiment can lead to massive long term gains in revenue.
How to increase conversion rate?
Use A/B testing to compare site elements and product attributes, then get data driven results and implement the winners.
How does Product A/B testing work?
- Use the app to select a product
- Change the product attributes on version B
- Start the test and let it gather data
- Check the stats in the app to see which version is winning
The app will swap the 2 versions every day at midnight and track the stats.
How does Theme A/B testing work?
- Duplicate your live theme
- Make a change to the new theme (maybe the add to cart button color)
- Choose the 2 themes to test and start the A/B split test
- Check back and analyze your stats to see which website features / version performs better
The app will swap the 2 versions at the interval you choose (daily, hourly, etc) and track the stats: Orders, Sales, Adds to cart, Visitors, Sessions, Page views.
How long to split test?
2 weeks is a good minimum time frame but the longer a test runs and the higher the statistical significance level, the more accurate your results will be.
What is statistical significance?
This is a mathematical formula to predict the probability that 1 version is better than the other.
Theme Scientist includes statistical significance calculations for every A/B test.
Free Theme Scheduler feature
You can set a theme to publish at a specific time in the future.
This is great for publishing promotions at exactly the time you want without having to be online to make changes or set a new theme live.
The scheduler is also useful for running daily flash sales where new themes / graphics need to be swapped every hour.
Who this app is for
- If you want to increase your conversion rate
- If you want to maximize the value of your inbound traffic
- If you want to learn what customers in your niche respond to best
Built with performance in mind
Our A/B testing works in the backend so this app won't affect your load speed like other apps.
In the store front there is 1 small analytics pixel that loads at the end of the page so it does not cause render blocking.

Really buggy app. Super scary. When it loaded it glitched my browser and things kept looping. In the end, it said the app couldn’t be loaded This app can’t load due to an issue with browser cookies. Try enabling cookies in your browser, switching to another browser, or contacting the developer to get support.
We responded to you immediately this morning but haven't heard back yet so going to try here.
2. We tested extensively today, for more than an hour on different stores, browsers, incognito mode, etc and weren't able to replicate the issue.
3. Nobody else has this problem with our app, and I noticed you left similar negative reviews on other apps, it sounds like it might be a problem / configuration with your browser, we can help you out.
Please let us help you, we're super techy folks and like solving problems :)

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!
Wow epic review thanks for sharing!
Haha ABT for sure that's the winner's mindset, testing is where it's at. We're happy to hear the app is helping grow your business, and we're very appreciative of you sharing your experience. Thank you
Super clean, powerful app that lets you alternate between themes for split testing. Being able to customize an entirely separate theme gives you almost unlimited flexibility to tweak and test.
It tracks the views, add to carts, conversion rates, and provides statistical significance levels so you know when to choose the winning version.
The team behind the app are great, I hired them in the past to speed up my site and add lazy loading to images. They're very responsive, always improving and building new features and products based on suggestions.
Right on thank you so much for both the review and complements to the team, we really appreciate it!
