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 am just now messing around with the features. I had some questions to start out and the customer service was GREAT to say the least! Nothing worse than dealing with a bot or someone who just shoves deals down your throat. The most basic part of this app lets me delete other apps I cant stand. Already off to a great start!

The app looks amazing, had everything you need to increase those cart values while still looking great on your theme. I needed some extra guidence on my theme and the team went way above and beyond to make the experience streamlined and easy. This app will pay for itself over and over again and more. highley recommend

The developers and customer service team are super helpful! they have always replied quickly and made the tweaks when possible and super friendly to talk to. 10/10 The only thing that is an area of improvement is the ability to customise the app ourselves. For example changing the padding between widgets and changing the button shape etc. Basically the aesthetic side of it. The developers can do a lot but even they are still limited with what they can do for some things. Design is really important for brand continuity so I hope this improves in the future.

This app is so good for boost your cart design and function, but I can't believe that this app have not a native support for language translation... the customer service suggest me to install another app for translate the text on the cart, but I, as all other people that use multilanguage Shopify, already have an app for translator, and is not acceptable to install (and pay) another app for translate... please STAFF do your best to integrate this, we already pay to use your app! P.S: I'm not asking for an integration with my translating app, but to let MonsterCart APP (a very game changer app) to let translate the text natively from the app settings.

We do not integrate with your existing translating app. As per support conversations.
Unfortunately, it's up to them to build the code to make it work. We are code wizards but we can't play God 😅 and force them to do it. - For anyone reading this... as we say in our integrations lists... we are compatible with the #1 language app on Shopify - Transcy. If other language apps want to support us feel free!!! 🙌🥰

Great app for increasing AOV in cart. Lots of powerful functions like "dynamic free shipping bar" to encourage customers to buy more than one. The owner of the app is also great, and provides hands-on support when needed!
