ThemeStack

The reviews are overwhelmingly positive. Users praise the app for delivering the sticky add-to-cart feature effectively, being easy to set up, and helping stores add useful custom functionality without needing to pay for expensive new themes. Several reviewers mention that the app improves the shopping experience and looks good on the site, with one specifically noting that the mobile setup was optimized for better UX. Support also stands out as a major strength, with a reviewer highlighting that Richard was very helpful in customizing the feature to work properly with multiple product variants. The main negative point is that the app may have some limitations out of the box, especially for stores with more complex product setups such as multiple variants. However, this appears to be more of a customization need than a major flaw, since support was able to resolve it. Overall, the feedback suggests the app is reliable, user-friendly, and valuable for merchants looking for flexible storefront features.
