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

don't even deserve to give a star ,the app isn't even responding

Customer support is really bad at responding to this app. Our data had discrepencies that don't make sense/ need explanation on almost every test and their team does not get back to you for at least 5 days when you have a question, sometimes never.

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!

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!

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.
