Vantre: Stress & HRV Journal

Some days you feel tired, tense or scattered and can't quite say why. Vantre reads what Apple Health already has and tells you, in one sentence, how today compares with your own usual: the same, higher, or lower.

When a day looks different, it asks one question: what happened today? Sleep, work, travel, exercise… You answer with one tap or one sentence. Those small notes add up, and Vantre shows you what keeps repeating.

No score. Vantre compares you with yourself, never with anyone else.

WHAT YOU GET
• Today: your day in one sentence and your last 14 days at a glance
• Heart rhythm (HRV), sleep and resting pulse, each shown next to your usual range
• One-tap notes, no long diary to write
• Journal: every past day with its readings and its note
• What keeps repeating: are your readings lower on days you noted "Work"? See it day by day
• Voice Check: speak or breathe for a few seconds; your voice is checked on your iPhone and never recorded
• Three breathing exercises
• Home Screen widget: how today looks, at a glance
• Five languages: English, Turkish, German, Spanish and Italian; choose yours inside the app

BEST WITH APPLE WATCH
Heart rhythm (HRV) and resting pulse come from an Apple Watch or another device that writes to Apple Health. Vantre reads them from Apple Health; there is no separate Watch app. Without those readings you can still take notes and use Voice Check and breathing, but the daily comparison needs readings.

YOUR DATA STAYS WITH YOU
• No account, no ads, no tracking
• Your health data is processed on your iPhone and stays there
• Vantre never writes to Apple Health; it only reads what you allow
• iCloud backup is optional, covers only your notes, and goes to your own account
