Cubby is the baby tracker for the 3am version of you. Every other tracker is bright, pastel and built for daylight. Cubby is dark by default, because the job happens in a blacked-out nursery with one hand free. ONE DIAL FOR THE WHOLE DAY Cubby draws your baby's day as a 24-hour clock. Sleep shows as arcs, feeds as spokes, changes as pips on the rim. One look tells you what kind of night that was — something no list of rows has ever managed. IT LEARNS WHEN THE NAP IS COMING Cubby measures your baby's actual wake windows and tells you when the next nap is likely, with an honest window rather than false precision. Until there's enough history it falls back to age guidance and says so. Most trackers put nap prediction behind a monthly plan; Cubby has no subscription at all. IT ALSO LEARNS THE FEEDS Next feed predicted from the median gap between recent feeds. FAST WHEN YOU'RE WRECKED • One tap starts and stops the sleep timer • Two taps log a bottle, a nursing session or a diaper • Big targets, tabular numerals, no hunting TRACK EVERYTHING THAT MATTERS Bottles, nursing timers per side, solids, sleep, diapers, pumping, weight, length, head circumference, temperature and medicines. MILESTONES AND SHOTS CDC milestone checklists by age and the routine childhood immunisation schedule, ticked off as you go. Most trackers skip both entirely. REAL WHO GROWTH CENTILES Weight, length and head plotted against the actual WHO Child Growth Standards — 3rd to 97th centile bands with the median through the middle, and your baby's centile named beside each reading. Built from WHO's own published tables, not an approximation. TWINS WELCOME Each baby gets their own log; switch with a tap. REMINDERS, ON DEVICE Optional nudges when a feed is likely due or the nap window opens. Scheduled on your iPhone — no push server involved. NOTHING TO SIGN UP FOR No account. No sign-up. No email. No ads. No subscription. Every feed, sleep and diaper you log stays on your iPhone — export the whole log whenever your pediatrician asks. No tracking of you across other companies' apps or websites, and nothing shared with data brokers. Cubby describes what you logged and estimates from your own data. It is not medical advice. Growth centiles come from the WHO Child Growth Standards and are there for context, not diagnosis — always talk to your pediatrician about anything that worries you. ## Version history (last 5 releases) ### 4.30 — 2026-09-07 Small wording improvements to the upgrade screens. ### 4.29 — 2026-09-05 Length now follows the units you already chose. There was no length setting before, so heights were always in centimetres even if you track weight in pounds — the one pairing whose growth chart is in inches. You'll find Length beside Volume and Weight in Settings; it starts on inches to match pounds, so if you were reading heights in centimetres, switch it back there. Your saved measurements themselves are unchanged. Editing an entry and then closing the sheet no longer discards what you typed without asking. A bottle logged with the amount stepped down to zero now records as “no amount” rather than as zero, so it no longer reads as though the baby drank nothing. The wake window on Patterns no longer reads “1h 0m”. ### 4.27 — 2026-09-03 Growth and temperature entries can be corrected from the edit sheet — a weight typed as 150 instead of 15.0 no longer has to be deleted. History pages back past 60 days, and no longer says nothing was logged when it was. Sleep across midnight now counts on both days, on the dial and in the daily total. The exported log keeps commas and line breaks in your notes exactly as you typed them. Every control is now named for VoiceOver, with selected and checked state announced. ### 4.20 — 2026-09-01 Cubby is a baby tracker now. This app started life as ShiftMD, a call scheduler for physicians. It has been rebuilt from the ground up as Cubby, a feed, sleep and diaper tracker built for the 3am shift. None of the scheduling features remain. What is inside: your baby's whole day drawn as a 24-hour dial, the next nap and next feed predicted from their own rhythm, real WHO growth centiles, CDC milestone checklists and the immunisation schedule, an Apple Watch app, logging by Siri, Lock Screen and Home Screen widgets, and a sleep timer that runs in the Dynamic Island. No account, no sign-up — your log stays on your iPhone. ### 4.4 — 2026-08-26 Cubby is a baby tracker now. This app started life as ShiftMD, a call scheduler for physicians. It has been rebuilt from the ground up as Cubby, a feed, sleep and diaper tracker built for the 3am shift. None of the scheduling features remain. What is inside: your baby's whole day drawn as a 24-hour dial, the next nap and next feed predicted from their own rhythm, real WHO growth centiles, CDC milestone checklists and the immunisation schedule, an Apple Watch app, logging by Siri, Lock Screen and Home Screen widgets, and a sleep timer that runs in the Dynamic Island. Free, no account, and nothing leaves your phone. ## More apps by Meng-Yi Hsu - [Bavarian Translator for Oma](https://appshunter.io/ios/app/bavarian-translator-for-oma/id6783592733) - [Gym Log: Lift & PR Tracker](https://appshunter.io/ios/app/gym-log-lift-and-pr-tracker/id6783645092) - [Copy History: Clipboard](https://appshunter.io/ios/app/copy-history-clipboard/id6783654287) - [Water Sort: Pour Puzzle](https://appshunter.io/ios/app/water-sort-pour-puzzle/id6783993369) - [SleepTracker: Watch or Phone](https://appshunter.io/ios/app/sleeptracker-watch-or-phone/id6784482382) All apps by Meng-Yi Hsu: https://appshunter.io/developer/6783592735 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
