Tibby: Baby Log & Sleep Timer

A baby log you can actually use at 3am: one thumb, in the dark, without an account.

Open it and you see the answer to the question you keep asking: when was the last feed? Not a list to scroll or a sum to do in your head — the time since the last feed, the last sleep and the last change, before you touch anything.

Tap once to log a feed, a sleep or a diaper change. The buttons sit at the bottom of the screen where your thumb already is, they are large, and every one of them carries a word — never a mystery icon you have to decode while holding a baby.

Four things together, and that is the point: the sleep timer runs on the Lock Screen and in the Dynamic Island, so a glance answers it; with Tibby Pro, growth is charted on the real WHO percentile curves, corrected for babies born early; nothing needs an account, a server or a signal; and the one purchase is a single one-time unlock, not a subscription.


WHAT IT DOES

• One tap logs. Feeds, sleeps and diaper changes, editable later.
• Sleep has a stop, and it is unmissable. Start it with one tap and end it with one tap.
• See a running timer on your Lock Screen and in the Dynamic Island, and stop it from there.
• Log from a Home Screen widget, from the Lock Screen, or by asking Siri — "log a feed in Tibby" — without opening the app at all. A second widget shows a ring of today's whole day at a glance, and the Lock Screen one answers "fed 2h 10m ago" before you unlock.
• On Apple Watch: the last feed at a glance, and Feed, Diaper and Start sleep — or Wake up — on your wrist.
• A night layout from 21:00 to 06:00: one number, three big buttons, nothing to read. Turn it off in Settings if you would rather not.
• Every button says what happened and when — "bottle · 3.5 oz, 2h 10m ago" — and tells you which side is next for a breastfed baby.
• "Next feed usually around 23:40", worked out from the last three days.
• Play the day: watch a day's feeds, sleeps and changes replay round the ring, and send it as one picture to the family chat.
• Trends over a week (a month or three months with Tibby Pro) — feeds, sleep and diapers, split into day and night: was last night one long stretch or five broken ones?
• Siblings or twins: add a child in Settings and switch with one tap; "Both" logs twins together. Free.
• Built for one phone; the log itself lives on the phone that made it.
• On iPhone Duo, open it up and the ring and the buttons sit side by side.
• Breast, bottle and pumping, with per-side timers and amounts in ml or oz.
• Weight, length and head circumference; with Tibby Pro, their WHO percentiles (and curves for weight and length), corrected for babies born early.
• A report for your pediatrician, made on your phone: a week free, longer with Tibby Pro.
• Export your whole log as a CSV, or back everything up to one file and restore it on a new phone — free, always.


NOTHING LEAVES YOUR PHONE

There is no account, no server and no network call in the logging path. Your Apple Watch talks only to your iPhone. Not "we promise not to look" — there is nowhere for it to go. It works in a basement, on a plane, and at 3am with the wifi out.

No ads. Not fewer ads, none.


WHAT IT COSTS

Your whole log is free, forever. Your record is yours, and exporting it as a CSV or backing it up to a file to move to a new phone costs nothing and never will.

Tibby Pro is one payment, once, and it widens what the app works out from that record: trends and the report grow from one week to a month or three months, and growth gains the real WHO percentiles for weight, length and head, with the curves. No subscription, ever.


BUILT FOR THE 3AM VERSION OF YOU

Dark by default, with the numbers large enough to read half asleep. Nothing pops up mid-entry — no rating prompt, no upsell, no confirmation dialog between you and a log.

Not a medical device. Growth percentiles reference the WHO Child Growth Standards and describe where a baby sits among healthy babies — a position, not a score.
