## What is Linden?

Know how you really are, before the day decides.

Linden reads your resting heart rate with a 30-second face scan — no wearable, no chest strap, no account. Point the front camera at your face and Linden turns subtle color changes in your skin into one trustworthy number, paired with one sentence about what it means for you today.

Your video never leaves your phone. The scan is processed on your device and deleted. We never see your face.

How it works
• Scan in the morning for a clean resting baseline
• Linden compares today against your own baseline, not a population average
• One observation, never a verdict — you stay in charge of what to do with it

Free, forever
• One scan a day
• Your resting heart rate with a daily read
• Streak, morning reminders, contextual tags, and your full history

Linden Plus
• Unlimited scans
• Patterns across contexts, weekdays, and times of day
• A weekly AI-written recap of what your numbers are saying (opt-in)
• A doctor-ready PDF summary of your last 30 or 90 days

Linden is a general wellness app, not a medical device. It does not diagnose, treat, cure, or prevent any disease or condition, and it is not a substitute for professional medical advice.

Linden Plus is an optional auto-renewing subscription: $4.99 per month or $39.99 per year in the US (prices vary by region). New subscribers get one free 30-day trial per Apple ID. Payment is charged to your Apple Account at confirmation of purchase — after the trial, unless you cancel at least 24 hours before it ends. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. The free tier — one scan per day with your full history — stays free.
