Common questions
Do the website and the app stay in sync?
Yes. Both use the same account; training records and plan progress sync.
Can I log without signal?
In the app, yes: keep logging sets and timing rest offline; records stay on the phone and upload once online. Starting and finishing a session need a connection. Exercise details you have opened, or that were saved before training, can be read offline.
I didn't get a code
Check the phone number or email, wait a minute and try again; if SMS does not arrive, sign in with email instead. Still stuck? Email us.
How do I turn off training reminders?
In the app, Me → Training reminders, or turn off notifications for “明刚笔记” in system settings.
How do I export data or delete my account?
Export training records from Account settings on the website; request deletion from Account settings or the app's Me tab. You can cancel before it is processed.
