Overview

WhatsFeel is an iOS companion app focused on meditation, sleep, and daily relaxation. Unlike traditional apps that play fixed recordings, it is entirely AI-driven: a smart voice assistant uses your real-time heart rate data to dynamically generate and adjust every line of guidance. ### Four Core Smart Assistants - **Nature Sounds**: High-quality natural white noise such as birdsong, rain, and campfires. Play them alone or as background audio for meditation and sleep sessions. - **Meditation Assistant**: Provides immersive, continuous AI-generated voice guidance to accompany your mindfulness practice. Supports nature background sounds and heart-rate-based guidance adjustments. - **Sleep Assistant**: Delivers a relaxing pre-sleep experience through evolving guidance paired with soothing nature sounds. - **Chat Assistant**: A Q&A-style agent you can talk to anytime about stress, anxiety, or emotional struggles to receive AI suggestions. This feature is completely free. ### Heart Rate Integration By connecting a Bluetooth heart rate device, the AI agent reads your biometric data in real time. When heart rate changes are detected, the AI adjusts the guidance topics and relaxation strategies accordingly. The app supports Coros, Garmin, Polar, and any bands, armbands, or chest straps that use the standard Bluetooth heart rate protocol (0x180D). ### Subscription Plans WhatsFeel is free to download and offers three tiers: - **Free Access**: Unlimited use of the Chat Assistant. - **Basic Monthly Subscription** (¥15.00): Unlocks continuous voice guidance from the Meditation and Sleep agents, without heart rate data sync. - **Premium Monthly Subscription** (¥58.00): Unlocks Bluetooth heart rate integration, real-time AI guidance based on biometrics, and custom voice options for the AI agents. ### Privacy & Security The app only records the data necessary to generate historical trends and analyze relaxation outcomes. All data is encrypted and never used for third-party commercial tracking. Please note that WhatsFeel and all its built-in AI agents are intended solely for daily relaxation and supportive guidance. They cannot replace professional medical diagnosis, psychological counseling, or treatment.
