Heart Coherence is an Android breathing-training app from breathingin.app, built around the Heart Coherence 365 method: 3 sessions per day, 6 breaths per minute, 5 minutes per session. It is not an AI tool, but an offline breathing timer, reminder, and practice-tracking app.
The app provides a timer, breathing exercise configuration, daily reminders, and history tracking. Users can set inhale, exhale, breath-hold phases, and total practice duration, as well as create, edit, and delete multiple breathing exercises. During a session, it indicates each breathing phase through animations, vibration, sound, and notifications. Even with the screen off or when switching to another page, users can continue practicing with vibration and audio cues. The app supports portrait and landscape modes, phones and tablets, and allows customization of colors, night mode, background images, and background music.
The description clearly states that there are no premium paid tiers, no ads, no subscriptions, no credit card required, and no online purchases, making it a fully free app. Its privacy approach is also a strong point: no registration is required, it does not request personal data, phone data, or WiFi permissions, and it does not need an internet connection. The only data stored is practice history, which is kept locally on the phone and deleted when the app is uninstalled. History can also be exported as CSV.
Its strengths are that it is lightweight, simple, usable offline, free from commercial interruptions, and supports fairly detailed breathing-exercise customization and habit tracking. For users who want to practice heart coherence breathing regularly, the feature set is already quite complete. Its limitations are that it has no AI capabilities, no personalized health analysis, and no medical guarantees. Supported languages are listed only as EN, FR, and IT, with no Chinese support indicated. The description only shows an Android version, with no iOS or web version found.
It is suitable for Android users who want to reduce stress, relax before sleep, train focus, or build a daily breathing habit, especially those who value privacy and do not want to register or go online. Since the description only provides a Google Play link, access and installation availability in mainland China cannot be confirmed and is assessed as unknown.
