Apple Health isn't syncing

Open the Health app, tap your picture, then Apps, then Stack Days, and turn on the data you want to share. Then in Stack Days, go to Settings and tap Sync now. The app brings in workouts from the last two years.

My coach isn't answering

A first plan takes a couple of minutes to write, and you can leave the screen while it works. If you see a message about a daily limit, the coach is resting until tomorrow. If something else goes wrong, try again, and email us if it keeps happening.

Forgot your password

Use "Forgot password?" on the sign in screen and we'll email you a reset link that works for an hour. If it doesn't show up, check your spam folder or email us from the address on your account.

Didn't get the verification code

Tap Resend on the code screen. Codes come from [email protected], so check spam for that address too.

Deleting your account

In the app: Settings, then Delete account. On the website: Settings, then Delete account. Your profile, plans, sessions, goals, coach conversations and imported workouts are erased straight away. Workouts the app saved to Apple Health stay there; delete those in the Health app if you want.

Is it medical advice?

No. Stack Days gives general training guidance. For sharp pain, swelling, dizziness or anything that persists, see a doctor or physical therapist.
