Applin Tester vs ScrollCraft

Applin is a framework for making mobile apps. It uses server-driven UI. If you know computer programming, you can use an Applin server library to make an app server, with pages and functions defined in the server's code. Then use the Applin client library for iOS to quickly make an iOS app that connects to your server and displays the pages. Applin Tester embeds the Applin client library for iOS and connects to any Applin server. As you develop your app server, you can use Applin Tester to connect to your server and display your app's pages. Applin Tester also displays Applin demo apps, with links to their source code.

ScrollCraft is a native iPhone, iPad, and Mac app for SwiftUI developers who want to design scrollTransition() effects visually, then copy or export the generated SwiftUI code. Use live sliders to tune opacity, scale, offset, blur, saturation, colors, and corner radius while the preview updates immediately. When the transition feels right, open the code view and take the generated SwiftUI into your own project. Highlights: Live preview for scrollTransition() experiments A focused Apple-platform workflow for exploring SwiftUI scroll effects Phase-specific controls for topLeading, identity, and bottomTrailing Readable SwiftUI code generated from your exact settings One free code copy, with a one-time Pro unlock for unlimited copying Pro export to .swift files and saved local presets No account, no tracking, no ads, and no subscription ScrollCraft is intentionally focused: it is not a code editor, compiler, or general animation suite. It is a small, native tool for learning, tuning, and reusing SwiftUI scroll transitions on iPhone, iPad, and Mac.
