What is Lubb?

Editorial review

Lubb is a mobile app that uses the iPhone's haptic engine to create a simulated heartbeat, helping users fall asleep by replicating the comforting rhythm of a sleeping partner's chest. The app allows users to adjust the beat pace from 40 to 90 BPM, customize the strength and feel of the vibrations, and optionally play a lub-dub sound through the speaker. It includes a drift feature that gradually slows the beat over 25 minutes, and supports timed sessions with a gentle fade-out. Lubb is designed for comfort, not treatment, and does not track or measure sleep. It offers a free tier with 10-minute sessions and paid plans for longer use.
