Log the night feed
with no ads, one hand.
Breast, bottle, pump, sleep, diapers, temperature, medicine, solids, and growth stay on this phone. No sign-up. Add a name and birthday, then start. Two phones share only the logs one of them is missing. Grandparents get a large-print PDF. They don't install the app.
Not a doctor's diagnosis. The next feed time is a guess from your logs.
In short
Logs stay on this phone. There is no SyncBaby server. On the same Wi-Fi, each phone gets the logs it doesn't have yet. On Android, you can also tap the phones together with NFC. The logging screen has no ads. Grandparents get a large-print PDF. One album a month, all 6 layouts, up to 10 pages, is free. So are the next feed, the nap time, and the 7-day doctor summary. Charging backup, 50 pages, season and holiday covers, and 30-day stats are Plus.
Easier at night
Two phones, only what's missing
On the same Wi-Fi, each phone gets the logs it doesn't have yet. On Android, tap the phones together for NFC. Matching is free.
Logs stay on this phone
There is no SyncBaby server. Make a backup yourself, or put it in your own Google Drive. You can set morning as the start of the day, so sleep past midnight stays on one day.
Grandparents skip the app
Make a large-print PDF and send it in any chat app. The file stays in Downloads. Free is one album a month, up to 10 pages.

Questions
Do logs go to a server?
No. Feeds, sleep, diapers, temperature, medicine, and photos stay on that phone. There is no SyncBaby server. Google Drive backup goes only to the Drive account you connect.
How do two parents match phones?
On the same Wi-Fi, each phone gets the logs it doesn't have yet. On Android, tap the phones together for NFC. Matching is free.
Do grandparents install the app?
No. Make a large-print PDF and send it in KakaoTalk, WhatsApp, or any chat app. The file stays in Downloads, even if you delete the app.
Is the next-feed time a diagnosis?
No. It's a time from recent logs. With only a few logs, the app starts at 3 hours and asks you to watch your baby first. If you're worried, ask your pediatrician.
