Yes — as long as both devices use the same Apple ID and iCloud sync is enabled for Weiban, your records will restore automatically. Keep the device online and give it a moment.

Without iCloud, create an encrypted .weibanbackup file from "Profile → Encrypted Backup & Restore" on the old device, then import it on the new one. CSV/PDF files are for viewing and archiving only.

1. Make sure you're signed in to your Apple ID, and Weiban is enabled under Settings → Apple ID → iCloud;
2. Check that your iCloud storage isn't full;
3. Stay online — sync usually completes within a minute but can be delayed by system scheduling;
4. Restart the app and check again.

Still stuck? Email us with the iOS versions of both devices.

Go to "Profile → Family Members" and send an invitation — the system generates an iCloud sharing link. Once accepted, everyone's records stay in sync.

• Each member signs in with their own Apple ID on their own device;
• You control invitations and can remove members at any time;
• Shared data lives in the organizer's iCloud private database via Apple's CloudKit — it never passes through us.

1. Check Settings → Notifications → Weiban and make sure notifications are allowed;
2. In the app's "Profile → Reminders", confirm reminders are on and that quiet hours don't cover the current time;
3. Check that a Focus mode isn't silencing the app (or add Weiban to its allowed list).

All reminders are local notifications — they work offline, but reminder state doesn't sync across devices.

No. Nursing and sleep timers keep running when you switch pages or lock the screen, and show the correct elapsed time when you return. Tap "Pause" whenever you need a break — resume anytime.

Yes. Find the record in the timeline and tap it to edit the time, volume, notes and more, or swipe to delete. The "Add past record" action on Home lets you backfill any earlier time.

Export and backup: CSV is best for spreadsheet analysis and PDF for pediatrician-friendly reports. To restore later, create an encrypted .weibanbackup file under "Profile → Encrypted Backup & Restore".

Delete: "Profile → Data & Privacy → Erase All Data" first leaves or stops Family Sharing, then wipes on-device data. If personal iCloud sync is enabled, the empty state also syncs to your other devices. This can't be undone, so create an encrypted backup first.

Weiban requires an iPhone or iPad running iOS/iPadOS 17 or later. It ships with light, dark and minimal-night themes, plus Home Screen widgets so you can see time since the last feed without opening the app.
