Theme Scientist A/B Testing

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

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.

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 :)

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!

Great app! Our team has been using this app for over a year to run A/B tests on products and website features - always testing something. We use a set it and forget it style: create a test, wait a few weeks or so, analyze the results, then start another test. The best for us has been testing product prices. Finding a better product price is golden!

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.

The best split-testing app I've tested so far, there is everything I need and the customer service is super reactive!
I also suggested a new feature and it got added !! 100% recommended

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!)

I used this app to run a test on the color of the buy button. It was easy to set up and it ran without a hitch. I did get a clear winner. I had an idea to make it work better and reached out to Joe, the founder. He was very responsive and did implement my suggestion. I highly recommend this app.

That is the A/B Split testing App I was waiting for long time!

We know the developer through his expertise in speed optimization. Great customer support, with passion that always goes a extra mile!

We were also told a few more features are in the pipeline for this App. Thus, we are really exited to see this app developing even further!
