Question: I'm looking for a tool that allows me to deploy apps on multiple devices with self-designing layouts that work across different screen sizes.

If you're looking for a tool that lets you deploy apps to many devices with self-arranging layouts that adapt to different screen sizes, Glide is a good choice. It's a no-code app builder that links to existing business data in spreadsheets or databases and deploys apps to all devices. The service offers features like adaptive layouts, advanced workflow creation and data integration, making it a good fit for business, IT and engineering teams.

Another good option is Power Apps from Microsoft. The low-code development service uses AI to build apps with tools like Copilot, AI suggestions and a drag-and-drop interface. You can deploy apps with confidence using its built-in deployment pipelines and manage your app at large scale. It also integrates with Microsoft Azure and Visual Studio, so it's a good choice for large-scale app development.

Bubble is another option. The full-stack no-code app builder uses AI to help you build and design apps, with hundreds of customizable templates and a drag-and-drop editor. It supports scalable and secure hosting, real-time collaboration and connections to many data sources. Bubble is good for startup projects and enterprise apps, so it's adaptable to different needs.

If you're more of a developer, FlutterFlow is a web-based service that uses a visual drag-and-drop interface to build modern apps that integrate with Firebase. It includes a UI builder with more than 80 Flutter widgets, real-time collaboration tools and the ability to publish to app stores or custom domains. It's good for small and large projects, offering flexibility and scalability.
