Lullwave, the App With Nothing to Ask of You

Field notes

Lullwave packages five touch interactions—ripples, light blooms, particle trails, waves, and bubbles—into an offline Android app identified as com.hushlab.lullwave. The site describes a dimmer and soft haptic feedback, while explicitly excluding accounts, notifications, adverts, purchases, progress tracking, and data collection. Its design rationale includes a 1,600-millisecond ripple example: the publisher argues that the longer fade reads as water, while a faster response feels like a button press.
