# Lubb

## About
Lubb is a sleep app for iPhone that simulates the feeling of falling asleep on a partner's chest by playing a soft heartbeat through the Taptic Engine. It is designed to be used under the edge of a pillow while the screen stays dim and true black for overnight sessions.

## Product summary
- Helps users fall asleep by playing a slow, soothing lub-dub rhythm.
- Adjustable pacing from 40 to 90 BPM, with a default around 55 BPM.
- Optional drift mode eases the beat down over the first 25 minutes.
- Feel and strength controls let users tune the rhythm to their pillow and bedding.
- Optional sound layer can add a low bedroom-friendly heartbeat tone.
- Built for overnight use with a true-black screen, wall-clock timing, and a gentle fade at the end of a timed session.

## Key features
- Drift: starts slightly faster than the selected pace and settles down over time.
- Feel and strength: round/organic to crisp, tuned to the phone's placement under the pillow.
- Optional audio: low lub-dub synthesis in sync with haptic timing.
- Zero-tap bedtime: start with Sleep Focus, Siri, or the Home Screen quick action.
- Free tier: 10 minutes at a time, as often as needed.
- Plus: unlocks longer sessions including 30-minute wind-down, 2-hour deep starts, and all-night sessions.

## Pricing
- Free: 10 minutes at a time, no account required.
- Yearly plan: $9.99 per year, with 7 nights free at the start of the trial.
