If you’re reporting a bug, it helps enormously to include your device model, your iOS version, and what you tapped just before it went wrong.
Common questions
Where is my data stored?
On your device, in a database only ZeeZee can read. It is never uploaded. There is no account to create and no server to sync with. See the privacy policy for the full detail.
How do I move to a new iPhone or iPad?
Open the Baby tab and save a backup file. Move that file to the new device however you normally move files — AirDrop, Files, iCloud Drive, email to yourself. On the new device, choose Restore a backup on the welcome screen and pick the file.
An encrypted iPhone backup or a device-to-device transfer also carries ZeeZee’s data across, because the database lives inside the app.
I deleted the app. Is my data gone?
Yes. Deleting the app deletes its database with it, and because nothing is stored anywhere else, there is no copy for us to restore. Save a backup file before you delete the app, and keep it somewhere safe.
Can I track more than one child?
Yes. Add each child from the Baby tab. Every screen — totals, timeline, stats, weight — belongs to whichever child is selected, and the app takes on that child’s colour so you always know which one you’re looking at.
Why does the Stats tab say it has nothing to show?
ZeeZee compares today against your baby’s own baseline, and a baseline needs several complete days behind it before it means anything. Rather than show you a number it doesn’t trust, it shows you nothing. Keep logging and it fills in.
Can I log a feed I forgot, or fix one I got wrong?
Yes. Tap any entry in the timeline to edit its time, amount or note, or to delete it. Use the calendar on Home to jump back to any past day and log into it.
Can I use ounces instead of millilitres, or pounds instead of kilograms?
Yes — both are per-child settings on the Baby tab.
Does it work offline?
Always. ZeeZee makes no network requests, so aeroplane mode changes nothing. The WHO growth reference used for percentiles ships inside the app.
Is ZeeZee medical advice?
No. ZeeZee is a record-keeping tool, not a medical device. It describes what you have logged and how it compares to your baby’s own recent pattern. It does not diagnose anything and does not tell you what to do. If you are worried about your baby, speak to your midwife, health visitor or doctor.
How much does it cost?
ZeeZee is free. There are no in-app purchases, no subscription and no ads.
