The guide

How BabyLogly works

Every feature, step by step: from your first nursing timer to sharing with your partner, the Apple Watch and BabyLogly Pro.

Get set up

  1. On first launch, add your baby’s name and birthdate. You can add more babies later.
  2. The app opens on Home. The quick-log bar at the bottom has Nursing, Bottle, Sleep, Diaper and Health.
  3. After your first entry, Today’s Summary cards appear. Tap a card to see the entries behind the number.
  4. No account to create. Your records stay on your devices and, if you turn on sync, in your own iCloud.

Time a nursing session

  1. Tap Nursing and choose Breastfeeding.
  2. Tap Left or Right to start the timer for that side. One tap switches sides. A marker shows which side you finished on last time.
  3. The screen shows the session total and the time on each side.
  4. Tap End & Save Session when you are done. Close the sheet to keep timing in the background.

Log a bottle, pumping or solids

  1. Bottle: tap Bottle, choose breast milk, formula or a mixed bottle, and enter the amount in ml or oz (switch units in Settings).
  2. Pumping: log the amount and the side you pumped.
  3. Solid foods: note what your baby ate and how it went: liked, refused, or a reaction.
  4. The Home cards keep the day’s totals. Optional feeding reminders tell you when it has been a while since the last feed, one per baby.

Track sleep

  1. Tap Sleep, then tap the circle to start the timer, for a nap or the night.
  2. The timer keeps running when you leave the app. If it is still running after 16 hours, it stops itself and asks you to check the time.
  3. Tap Stop Timer when your baby wakes, adjust the times if you were late, and save.
  4. Forgot the timer? Use Log Past Sleep to add it afterwards.

Record a diaper

  1. Tap Diaper, then Wet, Dirty, Mixed or a clean check. One tap logs it with the current time.
  2. To change the time or add a note, open More options first.
  3. Daily counts appear on Home and in the Timeline.

Log fever and medicine

  1. Tap Health. Enter a temperature and how it was measured (oral, ear, forehead, rectal), or leave it empty to log only a dose or a note.
  2. Add the medication name, dose and unit. The form shows when the last dose of that medicine was logged.
  3. The temperature history is charted over time, ready for a doctor’s visit. BabyLogly records what you enter; it gives no medical advice.

Track growth

  1. Open the Growth card on Home and add weight, height and head circumference. Each field is optional.
  2. Use metric or imperial units. The chart shows every measurement over time.

Review and edit the Timeline

  1. The Timeline tab shows every entry of the day in order, with who logged it.
  2. Filter by type, or tap the date to pick another day.
  3. Touch and hold any entry to edit or delete it. Use + on Home to add something that happened earlier.

Share with your partner or a caregiver

  1. Go to Settings › Family Sharing, pick a baby and send an invite through Messages, Mail or a link.
  2. Choose whether the person can edit entries or only view them.
  3. Once they accept, you both see the same log, updating live through iCloud. Each entry shows who logged it, and you can get a notification when your partner logs something.
  4. Either of you can stop sharing at any time.

Several babies

  1. Tap your baby’s name at the top of Home and choose Add Baby.
  2. Switch babies from the same menu. Each baby has its own log and timers.

Apple Watch

  1. Open BabyLogly on your Apple Watch to start or stop the nursing and sleep timers from your wrist.
  2. A timer started on the iPhone shows on the Watch, and the other way round. Stop it on either.
  3. Complication: touch and hold your watch face, tap Edit, and add BabyLogly. It shows the time since the last feed, or the running timer. It is also available in the Smart Stack.

Live Activities and Dynamic Island

  1. A running nursing or sleep timer shows on the Lock Screen and in the Dynamic Island.
  2. Glance without unlocking, and tap to go straight back to the timer. You can turn Live Activities off in Settings.

Widgets

Touch and hold the Home Screen or Lock Screen, tap Edit, then Add Widget, and choose BabyLogly. There are eight widgets:

  • Since Last Feed (small): time since the last feed, which side is next and who logged it.
  • Start a Feed (small): start nursing on the suggested side with one tap.
  • Today at a Glance (medium): today’s feeds, sleep and diapers.
  • Quick Log (medium): log a wet or dirty diaper, a bottle or sleep without opening the app.
  • Recent Entries (large): the last six entries and who logged each one.
  • Fever and Medicine (small): the last temperature and how long ago the last dose was. Times only, no dosing advice.
  • Feed Ring (Lock Screen): minutes since the last feed; the ring fills toward your baby’s usual gap between feeds.
  • Status (Lock Screen): last feed, last diaper, and whether the baby is asleep.

Tap a widget to open the matching screen, or an entry to jump to it in the Timeline.

Control Center and the Action button

  1. Add BabyLogly controls to Control Center: start or stop the nursing timer, start or stop the sleep timer, or log a wet diaper.
  2. On iPhones with an Action button, assign one of these controls in the iPhone Settings app under Action Button.

Siri

Say these to Siri. They also appear in the Shortcuts app.

BabyLogly itself runs no AI and sends your data nowhere.

Switch from Nara Baby

  1. In Nara Baby, export your data as a CSV file.
  2. In BabyLogly, go to Settings › Data & Backup, tap Import from Another App and choose the file.
  3. You see what will be added before anything is saved. Entries BabyLogly has no screen for yet (for example milestones or vaccines) come in as notes with the original text, so nothing is lost. Importing the same file twice adds nothing.

Export your data

  1. Go to Settings › Data & Backup and export everything as a CSV file, for your pediatrician or your own records.
  2. A BabyLogly export can be imported again, for example on a new phone.

BabyLogly Pro (optional)

Everything you use today stays free. Pro is a monthly or yearly subscription with two extras. Find it in the Insights tab.

  • Doctor Summary: a PDF for any date range with feeds, nursing, bottles, sleep, and wet and dirty diapers per day, daily averages, and every temperature, dose and growth measurement. It lists what was logged and gives no medical advice.
  • Trends: feeds, sleep, wet and dirty diapers and bottle volume per day over 4 weeks, 3 months or 12 months, and this week against last week.

Payment is charged to your Apple Account. The subscription renews automatically unless you cancel at least 24 hours before the end of the period. Manage or cancel it in Settings › [your name] › Subscriptions. Use Restore Purchases on a new device.

Privacy and iCloud

  1. Your records stay on your devices. Turn on iCloud sync in Settings › Data & Backup to keep your iPhone, Apple Watch and other devices in step, in your own private iCloud.
  2. No ads, no AI, no account, no third-party analytics. Read the privacy policy.
