Bellwether Circle

Bellwether Circle helps families and loved ones care for each other without having to ask "How are you doing?" every single day. The app gathers health metrics from your phone or smartwatch and turns them into a short, clear summary shared exclusively with the people you invite into your circle.

How It Works

Connect Health Connect (Android) or Apple Health (iOS): The app reads your steps, activity, distance, workouts, calories, sleep, heart rate, and heart rate variability (HRV).

Daily Digest: Once a day, this data is condensed into a brief summary showing how you slept, how much you moved, and whether your day was calm or stressful.

Family Circle: Create a circle and invite your parents, partner, or friends. Sharing is mutual: you see the exact same categories for them as they see for you.

Morning Updates: Receive a gentle morning notification reviewing how your loved ones slept and moved.

Smart Alerts: If a metric significantly deviates from a person's baseline, the app highlights it so you can send a warm check-in message.

What the App Tracks

Sleep: Duration, sleep stages, quality score, and 30-night history.

Activity: Steps, workout minutes, distance, calories burned, daily goal progress, and weekly or monthly trends.

Heart: Daily heart rate (minimum and maximum), heart rate variability, and estimated stress level.

Privacy and Health Data

Purpose-Driven Use: Health data is used strictly to power app features and sync daily summaries between your circle members.

Read-Only Access: The app only reads health metrics—it never writes data back to Health Connect or Apple Health.

No Data Sales: Your health data is never sold or shared with third parties for advertising.

Mutual & Revocable: Sharing is always two-way and limited to invited members. You can remove anyone at any time, instantly stopping data sharing.

Background Sync: Background data access is used solely to keep your daily summary updated when the app is closed.
