Delta with Haptics

Haptic Testing is the tool for iOS developers and designers who want every touch to feel just right. Feel every haptic on iPhone and Apple Watch, see it visualized, and copy the Swift code straight into Xcode.

FEEL EVERY HAPTIC

• Impact: Light, Medium, Heavy, Soft and Rigid — for buttons, toggles and collisions
• Notification: Success, Warning and Error — the feel of an outcome
• Selection: the light tick of a changing value
• Try haptics with native iOS elements: stepper, context menu, rotation and more

CUSTOM PATTERNS

• Compose Core Haptics patterns with intensity, sharpness and timing
• Combine short (transient) and long (continuous) events
• Play them on iPhone and Apple Watch

ADVANCED VISUALIZATION

• See the shape of every haptic — what you feel, on screen
• Compare with ease: Light vs Heavy, Soft vs Rigid

APPLE WATCH

• Feel every watchOS haptic right on your wrist
• No watch at hand? Use the built-in Apple Watch simulator on your iPhone

READY-MADE CODE

• A Swift snippet for every haptic
• Copy or share with one tap — less guesswork, more time saved

WHO IS THIS APP FOR?

• App developers: find the right feedback for every action
• Game developers: craft immersive tactile experiences
• UX/UI designers: bring interfaces to life with haptics
