Common questions

How do I sync with my Apple Watch?

Make sure your iPhone and Apple Watch are paired and that Sweathearts is installed on the watch. Start a session on either device — logging on one advances both, since they share a single workout session.

My data isn't syncing.

Sweathearts is offline-first, so your logs are saved on your device and sync when you have a connection. Check that you're signed in and online. If it persists, email us and we'll help.

How do I change my theme?

Go to Settings inside the app and choose Daylight, Patisserie or Forge Dark. It switches instantly — no restart needed.

How do I connect Apple Health?

When prompted, grant Sweathearts permission to read and write health data. You can review or change this any time in iOS Settings → Privacy & Security → Health → Sweathearts.

How do I delete my account?

You can delete your account and all associated data from within the app, or follow the steps on our Delete Account page.
