A macOS app that generates Apple Watch-style activity indicator image sequences for WatchKit animations.
JBWatchActivityIndicator is a macOS application that generates custom activity indicator image sequences specifically designed for Apple Watch apps. It addresses the initial limitation in WatchKit where no native activity indicator control existed, allowing developers to create Apple-like loading animations through an interactive interface. The tool exports properly formatted PNG sequences that can be bundled with WatchKit applications.
iOS/macOS developers building Apple Watch applications using WatchKit who need to implement custom loading indicators that match Apple's design language.
Developers choose JBWatchActivityIndicator because it provides a visual, interactive way to create professional-looking activity indicators specifically optimized for Apple Watch, eliminating the need to manually design or source appropriate animation frames.
An easy way to generate activity indicator images for Apple Watch
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Offers an interactive GUI to adjust attributes like size, color, and style, as shown in the example GIF, enabling easy prototyping of custom indicators without coding.
Generates image sequences that match Apple's design language for WatchKit, ensuring professional and native-looking loading animations for Watch apps.
Exports properly numbered PNG frames ready for inclusion in Watch app bundles, with logged paths for easy copying, streamlining the asset preparation process.
Includes a JBWatchActivityIndicator class to programmatically generate image sequences on-the-fly, allowing for dynamic use cases beyond pre-bundled images.
As a macOS-only application, it excludes developers on Windows or Linux, reducing accessibility and forcing dependency on Apple hardware for design work.
Requires exporting images and manually adding them to the app bundle, which is cumbersome and error-prone compared to integrated asset catalogs or code-based solutions.
Targets early WatchKit gaps; with newer WatchOS versions, native indicators or SwiftUI components may make this tool less necessary, as hinted by the README's context.
