Pulsar
Rich and ready-to-use haptics library
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.
I’m Krzysztof, and I’ve been building mobile apps for years. Every time I wanted to add haptics, I had to guess, compile, deploy to a device, and repeat – only to realize the result felt completely different from what I’d imagined. There had to be a better way.
Haptics are vibrations, just as sound is a vibration of air. We’ve always had amazing tools for audio: DAWs, preset libraries, sound design kits. Why not for haptics?
So I did my research and built Pulsar: a haptics library that offers completely free haptic presets you can browse, filter, actually hear in your browser, and feel on your phone!
I’d love to hear from you:
👉 What’s the moment in your app where haptics make the biggest difference?
