    I have been using this app for a few months. It’s a very great tool for conversion. Love the customized campaigns and that the app is fully customizable. The customer service is really great and they get back to you super fast. Definitely give this app a try especially if you are looking for creative ways to increase your conversion. Love this app

    I searched around hard for an app that would help me increase my AOV and conversion rate and after checking out the demo for this app, I finally decided to give it a try. I reached out to customer service via chat and he took his time to help me set up everything patiently. I'm delighted with their customer service and they obviously care about your experience. The app has a lot of exciting features too. I'm completely satisfied with my experience. Thank you!
