Make a one-of-a-kind phone case on your phone!
CaseDiy is an app that allows you to easily create a beautiful, durable, and unique phone case, turning your inspiration into a reality in just three minutes.

A Simple, Yet Powerful Design Experience
Our core value is “Simple · Unique”. You don’t need to be a professional designer to create professional-level work. The entire process is very simple: Pick your phone model, choose a template, add your photos or your favorite stickers, and you’re done.

CaseDiy supports the latest iPhone models, popular Samsung models, and many other mainstream devices (50+ models in total), so you can easily find the right fit. We also offer multiple materials and MagSafe-compatible options.

Our smart layout technology automatically adapts your design to your phone’s camera and edges. We support high-resolution photo importing to ensure the final printed product is sharper. You can also switch colors and textures with a single tap and see the results in a real-time 3D preview, achieving a “what you see is what you get” experience. All drafts are saved to the cloud, allowing you to continue your creation anytime.

High-Quality Product and Sharing
We use top-tier printing technology to ensure every case is scratch-resistant with long-lasting, vibrant colors. CaseDiy makes it easy to share your creations. With just one tap, you can generate shareable images or videos suitable for social media. You can also collaborate with friends to co-create matching cases. Your designs are saved to your account, making it convenient to reorder at any time. A custom phone case also makes a very thoughtful gift, whether for an anniversary, a holiday, or as a matching item with someone special.
