Pulsar

Rich and ready-to-use haptics library

What it does

Pulsar is a collection of 150+ ready-to-use haptic presets for Swift, Kotlin, and React Native. Browse, filter, and preview presets with audio in the browser and on the simulator. Test them on a real device before deployment using our app. Curated filters help you find the right preset for any interaction. For more control, build custom presets with the Pulsar API or create real-time, gesture-based haptics both on iOS and Android.

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
