Custom Haptic Patterns With Core Haptics in React Native

Want your React Native app to feel physical with custom haptics? The short answer: on iOS, custom patterns run on Core Haptics, which you reach through a native bridge, and you compose them as sequences of taps and vibrations with intensity and sharpness. A crisp tap on success, a sharp buzz on error. The hard part is not the API, it is taste: haptics are punctuation, not a soundtrack. Pair the feedback with a free VP0 design, the free iOS design library for AI builders.

Who this is for

This is for React Native builders who want their app to feel responsive and premium through touch, and who want to use Core Haptics tastefully rather than buzzing users into turning feedback off.

How custom haptics work

Simple impact and notification feedback is easy, but custom textures come from Core Haptics, a platform capability you reach from React Native through a native module or a maintained haptics library, with Expo Haptics covering the common cases. A custom pattern is a timeline of events: transient events are sharp taps, continuous events are sustained vibrations, and each has an intensity (how strong) and a sharpness (how crisp versus dull). You sequence those into a feel, a double-tap confirmation, a rising buzz, a textured rumble, using the CHHapticEngine. The system can play these only on supported devices, so you design a graceful fallback to basic feedback elsewhere.

Concept	What it is	Use it for
Transient event	A sharp tap	Confirmation, selection
Continuous event	A sustained buzz	Error, alert, texture
Intensity	How strong	Match the moment’s weight
Sharpness	Crisp vs dull	The character of the feel
Fallback	Basic impact	Unsupported devices

Build it free with a VP0 design

Pick a design with interactive moments from VP0, copy its link, and prompt your AI builder:

Rebuild this VP0 design in React Native and add tasteful Core Haptics: [paste VP0 link]. Use a crisp transient tap to confirm success, a sharper pattern for errors, and selection feedback on key controls. Reach Core Haptics through a native module or haptics library, fall back to basic impact feedback where unsupported, and respect the system haptics setting.

The reach is enormous, with Apple reporting more than 1,000,000,000 active iPhones, nearly all of which carry the Taptic Engine that Core Haptics drives. Good haptics follow the same restraint as good motion, and Apple’s guidance on playing haptics stresses meaning over decoration. The craft pairs with other microinteractions like a confetti cannon animation in SwiftUI, a leaderboard podium animation, a Duolingo-style streak flame animation, and the gesture feel in dating-app swipe UI components. For a map-heavy screen next, see a Zillow-style map clustering UI.

Restraint is the whole skill

Here is the part that separates delightful from annoying. Haptics should mark meaningful moments and then get out of the way. Confirm a purchase, signal an error, mark crossing a threshold, but never vibrate on every scroll or buzz constantly, which drains battery and trains users to disable feedback. Respect the system setting and the user’s choice, and test on a real device because the simulator does not reproduce the feel. Used with restraint, haptics make an app feel alive; overused, they make it feel broken.

Common mistakes

The first mistake is overusing haptics until users turn them off. The second is ignoring device support and the system setting. The third is decorative vibration with no meaning. The fourth is testing only in the simulator, which has no haptics. The fifth is paying for a haptics kit when a free VP0 design plus Core Haptics does it.

Key takeaways

• Custom haptics run on Core Haptics, reached from React Native via a bridge.
• Compose patterns from transient and continuous events with intensity and sharpness.
• Use haptics to confirm and reward, never as constant vibration.
• Respect device support and the user’s system setting, with a fallback.
• Build the UI free from a VP0 design.

Frequently asked questions

How do I add custom haptic patterns in React Native? Reach Core Haptics through a native module or haptics library, compose patterns from transient and continuous events with intensity and sharpness, and trigger them on meaningful moments.

What is the safest way to add haptics with Claude Code or Cursor? Start from a free VP0 design, use Core Haptics via a maintained library with a fallback, use feedback sparingly, and respect device support and the system setting.

Can VP0 provide a free SwiftUI or React Native template with haptic feedback? Yes. VP0 is a free iOS design library; pick an interactive design and your AI tool rebuilds the UI while you add tasteful Core Haptics at the right moments.

When should an app use haptics? To mark meaningful moments like success, error, or selection, never constant or decorative vibration, so the app feels responsive without annoying the user.
