Nice app the support replies very fast aswell

At BauUniverso™, we move fast — and so do they! I had a technical issue on my store that needed urgent attention. The MonsterApps team jumped in immediately, diagnosed the problem, and fixed it in just a few hours. Not only did they solve the main issue, but they also double-checked that all colors, sizes, and features were perfectly updated and running smoothly. Their communication was crystal clear, fast, and human — something you don’t often find in tech support. In an industry where delays are common, MonsterApps stands out for their speed, skill, and genuine care for their clients. They didn’t just meet expectations — they went beyond. Highly recommend them to anyone who values reliable, proactive, and high-quality support. Thanks again, MonsterApps — I’ll be recommending you every chance I get! — Founder & CEO — BauUniverso™

Probably the most prompt and thorough app support I've ever received.

Charlene was very helpful and easy to chat with. Made my experience with Monster Cart seamless, highly recommend.

I can’t recommend the Monster Checkout Cart app enough! It’s incredibly customizable, easy to use, and integrates seamlessly with my Shopify store. What really sets it apart is the customer service — they respond so quickly and go above and beyond to help with any questions or tweaks I need. I love how flexible the app is, and it has made a huge difference for my store’s checkout experience. Truly impressed and very happy with both the app and the support team!

Very quick and responsive. I really enjoy working with them and their support staff.

The Monstercart upsell app looks amazing. I'm currently still going through setup, and have had an incredible experience with support helping me through some of my initial setup already.

Excellent experience with customer service team (Angelica in particular). Responses are always prompt and they've been very helpful in getting the cart to show on our site!

This app has great features and the best customer service I have ever experienced! Super fast replies and they always go above and beyond to solve any problems.

Super service! I had some questions about my cart and was immediately and kindly helped by Charlene. She really thought along with me and made sure everything worked perfectly. You can tell that she knows her stuff and that customer satisfaction is important to her. Thanks to her everything runs smoothly now. Really great - thank you Charlene and Monster Cart!

Great experience. Very quick service.

Very helpful customer service, they helped me 2 separate times in 2 days both times they solved the issues in no time at all. The first was integrating the Shopify cart to monster as the shop cart icon to avoid confusion and the second was helping resolve an issue with my gift tiers. Thanks team!

I've always had such an amazing experience with Monster Upsell. The customer service team are swift with their replies and so helpful. Charlene is fabulous. A super easy app to integrate into your store. Highly recommend

Angelica was very helpful in troubleshooting and fixing up the issue when we had trouble setting up the free gift offer. Response time is very quick and she was able to get it sorted in no time.

So far we're loving it! We had a minor issue with a gift with purchase promotion we were running but the issue was swiftly resolved by the customer service team and our campaign was up and running asap.
