Dropsource is a no-code mobile app development tool that allows users to create native apps for iOS and Android with features like offline storage, push notifications, and geolocation, while providing access to the native code in languages such as Swift, Java, and Flutter. It offers a drag-and-drop editor for designing user interfaces and managing data, and users can test their apps on devices or simulators before submitting to app stores, although apps can only be published to either iOS or Android, not both. Dropsource provides two pricing plans: the Individual Developer plan, which allows unlimited app building for free but charges $999 annually per app for deployment, and the Enterprise Developer plan, which offers tailored pricing and additional features. Comparatively, Bubble, a leader in the no-code space for web apps, provides tools for building customizable web applications with a strong community and extensive integrations, though it does not natively support mobile app development. Both platforms offer responsive editors, community support, and API connectivity, but differ in their focus, pricing, and available templates, with Bubble providing more extensive payment integrations and user management options.
