While there isn't a dedicated Google Sites app for mobile devices, you can't directly create a site from your phone using the official Google Sites platform. However, there are alternative approaches to consider:

• Use Google Sites on a web browser: You can access the Google Sites website (https://sites.google.com/) through your phone's web browser. The functionality might be slightly limited compared to a desktop experience, but it should still allow you to create a basic site with text, images, and layouts.

• Explore Third-party website creation tools: There are various website creation tools available on the Google Play Store or App Store that offer mobile-friendly interfaces. These might not be directly integrated with Google Sites, but they can help you build a website and potentially offer options to publish it later.

Here are some additional things to keep in mind:

• Building a complex website with a lot of features might be challenging on a phone's smaller screen.

• Editing text and formatting content might be less precise on a phone compared to a computer.

If you prioritize a mobile-friendly experience for creating your website, consider exploring third-party website creation tools. But for a more robust editing experience and full functionality of Google Sites, using a computer is recommended.
