01Health and safety boundaries
Health and safety
Seek immediate medical help for these signs
Abnormal breathing, blue face or lips, persistent high fever, seizures, severe dehydration, unusually poor responsiveness, inability to feed, unusual medication reactions, injuries, or other emergency signals. Call your local emergency number or go to urgent care; do not rely on app statistics, reminders, or growth percentiles to decide.
Temperature and medicine records do not generate medical reminders automatically. WHO growth references only organize measurements and never provide a diagnosis.
02Getting started
Getting started
OnboardingPages 0–9 introduce quick logging, the family code, stage profile, photos, common records, reminders, local data, and your first entry.
Quick loggingHome-screen buttons follow your baby’s stage. You can adjust common records in Settings.
Profile detailsOnboarding asks only for the stage. Birth date and reference sex can be added later in Settings.
Invitation codes“I have an invitation code” is shown as coming soon; the current version does not require a code.
03Frequently asked questions
FAQ
What if I enter a record incorrectly?
Open the record detail to view, edit, or delete it. Changes save locally and update according to sync rules when iCloud or Family Sharing is enabled.
Can timers be paused?
Nursing, sleep, bath, and outdoor timers support pause, resume, and finish. Timer state is persisted and can recover after the app unexpectedly exits. Live Activity display depends on system settings and device support.
Does the app read my whole photo library?
No. Photos are selected through the system photo picker. Until you choose an image, the app does not read your library. After selection, only that image is copied into private local storage.
How do WHO growth percentiles work?
First optionally add birth date and reference sex in Settings, then enter weight, height, or head circumference. The app uses monthly L/M/S data from WHO Child Growth Standards to calculate percentiles and Z-scores, switching from length to stature references after 24 months. Results organize measurements and are not a diagnosis.
Why do reminders cover only some records?
The current version supports feeding-interval and to-do reminders, and can write reminders to the system Calendar. Health records remain manual to avoid automatic medical judgments. You can turn notifications off in system settings.
How do I export records before changing phones?
Go to Settings → Data & Backup → Export Records CSV. Export includes record time, type, values, details, and notes. A complete backup of baby profiles, photos, and documents is still being improved. When changing devices, prefer iCloud restoration with the same Apple ID.
Why has iCloud sync not started?
Personal mode stores data locally with SwiftData and mirrors it to your own private iCloud database. Family Sharing uses a CloudKit shared zone after you create or join a family. Sync requires iCloud sign-in, network availability, and a valid Family subscription state.
Whose iCloud storage does Family use?
Family cloud data lives in a CloudKit shared zone created by the family owner and primarily counts against the owner’s storage. Members keep local data/cache and can read and write the shared zone. We recommend that the family member who will use the app long term and has sufficient iCloud storage create the family.
Do we need Apple Family Sharing or shared iCloud+?
No. Daybub Family is in-app collaboration joined with a six-character code or link, for up to 6 members (owner plus 5 invitees). Members do not need to be in the owner’s Apple Family Sharing group or share Apple iCloud+ storage, but each member must be signed in to an available iCloud account.
Will records be lost if the owner runs out of iCloud space or a member is offline?
No. Records already saved on device are not deleted for this reason. Missing iCloud sign-in, network failure, or insufficient owner storage pauses sharing/sync until sign-in, network, or storage is restored. If Family Annual expires, existing records also remain; family collaboration and member-derived Plus pause.
What is stored in the public invitation directory?
The current version stores only the six-character invitation code and CKShare link as business fields (CloudKit system record metadata also exists) needed to locate the family shared zone. It does not store the family name, member names, care records, or photos. Treat codes and links as sensitive and regenerate them when needed.
