Nesty: Baby Tracker, Sleep Log

Nesty is a baby tracker for ages 0 to 7: a breastfeeding timer, a nap and night sleep tracker, a diaper log and a WHO growth chart in one app, quiet enough to use at 3am with one hand. Two taps per entry Feed, sleep and diaper each have their own tile, low on the screen where a thumb lands, in a dark view that does not wake the room. Breastfeeding timer, left and right The two sides run as separate timers you can pause and resume, so a feed that stops and starts still adds up correctly. Send the app to the background and both sides pause themselves; a restart brings the session back with the totals intact. Bottle feeds are logged in ml or oz, and a combo feed holds breast time and bottle volume together. Sleep tracker for naps and for nights A session runs from the tap that starts it to the tap that ends it, across midnight and across a restart, so the time your baby fell asleep is the real one and not a morning estimate. Wake windows and the next nap Nesty takes your baby's age and the time of the last waking, applies the wake window that is typical at that age, and puts the next likely nap on the home screen with a quiet notification ahead of it. That is enough warning to dim the room before the overtired crying rather than after. The card is honest about what it is: average guidance from typical wake windows. Diaper log in one tap Wet, dirty or both, with an optional colour note. Growth chart with WHO percentiles Height and weight against the WHO Child Growth Standards for boys or girls, in metric or imperial units, so you see the trend before the checkup rather than in the waiting room. Handover card Last feed and what it was, last sleep and how long it ran, and the initials of whoever logged them. It is the first thing on the home screen when you come home from work or take over at 4am. A separate account for every caregiver Invite a partner, a grandparent or a babysitter with a link or a QR code that works once and expires after 72 hours. Entries carry the name of the person who made them and reach the other phones within seconds, which is the end of the "has she eaten yet" messages. An offline baby tracker Entries are written to this device first and sync on their own once you are back online, so a plane, a basement or one bar of signal in the nursery changes nothing about how you log. Undo and backdate Undo the last entry, correct a time, or move back a day to fill in what you missed while you were asleep. Weekly charts Weekly sleep, weekly feeds and weekly diaper changes, each with a daily average. Widget and watch The home-screen widget shows the last entry, and a tap opens the right screen. Galaxy Watch logs a feed, a sleep or a diaper from the wrist; anything logged away from the phone queues up and syncs itself. What an entry keeps Feeding: start time, minutes on each side, bottle volume, and whether it was breast, bottle or combo. Sleep: start, end, total, and nap or night. Diapers: type, time and an optional colour. Growth: height, weight, date and percentile. For the pediatrician Export 7, 14 or 30 days, or a custom range, as a PDF summary with total feeds, bottle volume, sleep sessions, total sleep, diaper changes and the latest measurement, or take the raw rows as CSV. Privacy Health entries about your child are never sold. Only the people you invite can see them, and account deletion lives inside the app. Who it is for Newborn parents counting wake windows, two parents splitting the night, grandparents and sitters who need a clean handover, and parents of toddlers and preschoolers up to seven. Ages 0 to 7, in 16 languages. Nesty supports your parenting; it is not medical advice. Wake windows and WHO growth references are guidance, not a diagnosis.
