Lull is a meditation app for iPhone, with its core positioning as "meditation that listens," emphasizing "less prescription, more presence." Instead of using an endless content feed, it encourages users to explore inward.
Purpose and how to use it: Users can tell Lull by voice or text what they are thinking and feeling at the moment, and the app generates meditation based on that content. The official description is that there is no need to search, no need to scroll, just say how you feel, and the app does the rest. Each practice is shaped by the user's emotions, the present moment, and the words spoken.
Main capabilities: Lull generates personalized meditations based on what users express; Lull Pro users can have up to 25 meditations per month newly generated from what the user says. As practice increases, the app better understands what users need. Users can also view their emotional changes by day, week, or month. The app offers a variety of guided voices, and users can choose for themselves a warm, gentle, calming voice. On the audio side, it supports clear sound quality, spatial audio, and an experience with smooth volume changes from beginning to end without abrupt shifts; users can also layer ambient sounds (such as rain, ocean waves, etc.) with meditation to create a personal atmosphere. In addition, users can share meditations with people who need them.
Heart rate and feedback: Lull does not give fictional calm scores, nor does it rate meditation performance. The official description mentions an "honest reading": keep the Lull Watch app open during meditation, and afterward Lull will show, when there is enough data, how much the heart rate has dropped relative to resting heart rate.
Pricing and trial: The free part is one set of guided meditations per day, which can be used long term; the official statement is that "free is a practice, not a trial preview." Lull Pro offers a real 7-day trial, and cancellation is located in Apple's own settings and can be completed in two steps. The official wording is "one plan, the price is the price."
Use cases: Suitable for iPhone users who want immediate, personalized meditation guidance because of overthinking, emotional fluctuations, or needing to settle at the end of the day; also suitable for people who want to combine meditation with personal mood tracking and observe their own changes.
Limitations and supplements: Official materials do not provide information such as an Android version, specific pricing, supported languages, the number and names of selectable guided voices, the specific number and types of ambient sounds, the specific hardware conditions required for heart rate monitoring, or medical claims. This content is not currently provided. The app does not include scoring of meditation effects, and the heart rate reference is only shown when there is enough data.
