## What is HapLab?

Feel your way to the answer.

HapLab is a haptics laboratory for iPhone: try the full vocabulary of the Core Haptics engine, combine it freely, and save what feels right. A design tool for people who build apps — and a playground for anyone who loves a good click.

■ PAD — touch and play
- Perform intensity and sharpness in real time on an XY surface
- Three modes: TAP (one hit), STREAM (sustained), BURST (repeats at 2–40 Hz)
- Light and vibration follow your finger while you touch

■ DICT — a dictionary of touch
- 44 samples that move one parameter at a time: intensity, sharpness, texture, envelopes, curves, rhythm
- Compare with the built-in iOS feedback (Impact / Selection / Notification)
- A/B the same haptic with and without sound

■ COMP — compose vibrations
- Place transients, sustains and synth sounds on a timeline
- Carve intensity, sharpness and envelopes (attack / decay / release) with sliders
- Modulate over time with intensity and sharpness curves, then loop and listen

■ LIB — remix the presets
- 12 presets: heartbeat, raindrops, engine, glass, alarm and more
- Open one, tweak it, save it as your own (free plan saves up to 3)

■ Light and sound as controls
- Toggle screen flash, glow, particles, torch (real LED) and synth sounds one by one
- Decompose what "feels good" into its parts

■ HapLab Pro (one-time purchase)
- Unlimited pattern saves
- JSON export — take the numbers you found into your own apps
- JSON import — play and remix shared patterns

■ Privacy
- No data collection. No ads. Your patterns stay on your device.

Haptic playback requires an iPhone with a Taptic Engine. The simulator and some older models cannot play haptics.
