Until Two is a calm log for a baby's first two years, and it stays on your iPhone. A dad built Until Two after his little one was born.
Log a feed, a bottle, a pump, a diaper, or a nap in one or two taps. Today opens on what just happened: asleep or awake, the last side or the last amount, the last diaper, and who wrote it down.
ON THIS IPHONE
There is no account and no server. Logging works with no network. Nothing in the log is uploaded, sold, or used for training. A care file leaves only when you send it, by AirDrop, Messages, Mail, or Files, and it is locked with a password you choose. The other phone opens it with that password and merges it. A PDF is a picture of a day for a pediatrician or a grandparent who only needs to read.
HANDS ON THE BABY
Start a timer or save a diaper from a widget, the Lock Screen, Control Center, or Siri: "Log a wet diaper in Until Two." A running timer sits in the Dynamic Island and on the Lock Screen, readable in a dark room, and stops without opening the app. On Apple Watch, see the timer, the last feed, and the last diaper, pause or switch sides, and start a timer or log a diaper from your wrist. The watch face shows the running timer or the time to the next feed.
ASK THE LOG
On an iPhone with Apple Intelligence and iOS 26.4 or later, ask in your own words, typed or spoken: when was the last feed, how long was the nap. Apple's model on this iPhone answers from the log and shows the entries it used, so you can check it. Answers can be wrong, and Ask does not give medical advice.
THE FIRST TWO YEARS
Nursing keeps both sides in one session and remembers the last side. Bottles in ounces or milliliters. Pumping and a milk stash, diapers, sleep, medicine, growth, solids, and routines as the months change. Activities you do not use disappear. Twins and corrected age are included. On iPad, Today and Insights sit side by side.
A summary for a visit lists feeds, diapers, sleep, medicines, and growth for the dates you choose.
QUIET ON PURPOSE
No streaks. No scores. No message that you are behind. Charts describe the days you logged. Wake windows and growth charts name their source. Until Two does not diagnose or prescribe.
YOURS TO DELETE
No ads. Delete the log on this phone whenever you want. There is no server copy to chase.
