Apply a Theme

Learn how to apply a theme to your app design. Choose a theme from the Theme Library and apply it to quickly update your app's appearance while keeping your content intact.

Overview

Ego Mobile Builder provides ready-made themes that help you create a professional mobile app design without starting from scratch.

Each theme includes pre-built layouts, components, and visual styles for a specific store category. After applying a theme, you can replace the demo content and customize the design to match your brand.

Applying a theme does not change your Shopify products, collections, orders, or store settings.

Available themes

Designed for furniture, home décor, lifestyle, and minimalist stores. It provides a clean and premium shopping experience.

Bloom Care — Beauty & Wellness Theme

Designed for beauty, skincare, cosmetics, wellness, and personal care stores. It focuses on visual storytelling and product discovery.

Open the Themes Library to view the latest available themes.
