Two Hearts is a free iOS and watchOS app that lets you share your heartbeat with friends and family. Using Apple HealthKit, it reads your heart rate and shares it with the people you choose.
Your Apple Watch reads your heart rate through Apple HealthKit. Two Hearts securely shares this data with your connected friends. You can also tap to send heartbeats as a way to say you're thinking of someone.
Absolutely. Your heart rate data is stored securely on Firebase servers and automatically deleted after 24 hours. We never share your data with third parties, and you control exactly who can see your heartbeat.
An Apple Watch is recommended for automatic heart rate readings, but it's not required. You can still send and receive heartbeats, view friends' heart rates, and use all social features on iPhone alone.
Yes, Two Hearts is completely free. No subscriptions, no in-app purchases, no ads.
Yes. You're always in control. You can remove friends or stop sharing your heartbeat at any time from your settings.
We only store your username, display name, profile picture, and heart rate data. Heart rate data is automatically deleted after 24 hours. See our Privacy Policy for full details.
Two Hearts works on iPhone running iOS 17 or later, and Apple Watch running watchOS 10 or later.
