Osca: Newborn Baby Tracker

Your baby's first days are personal. Keep them that way with Osca, a privacy-first baby tracker for feeds, sleep, diapers and the moments that matter. Track care on your device or choose to share it with your family using end-to-end encryption. Designed for the moments when your hands are full, from daytime cuddles to nighttime feeds.

PRIVACY COMES FIRST Use Osca on your device without setting up family sharing. Your care records are stored locally, and everyday tracking works offline. When you enable family sharing, shared care records and photos are end-to-end encrypted. Only approved family devices can decrypt them. The sharing service cannot read their contents. No email address, phone number or account signup is required.

CARE TOGETHER, SHARE PRIVATELY Invite your partner, grandparents or babysitter with a QR code. Keep feeds, sleep, diaper changes, notes and photos together across linked devices, so the people caring for your baby can follow along. Keep logging offline. Updates sync when you reconnect and open Osca. As the family creator, manage invitations and remove access as your family's needs change.

HOME SCREEN WIDGETS Start and stop sleep sessions or time contractions directly from your Home Screen. See your baby's sleep status and review contraction session summaries at a glance. Choose small or medium widgets to fit your Home Screen. Available on iOS 17 or later.

MADE FOR ONE-HANDED USE Holding your baby? Keep everyday logging within reach. Position the quick-add button on the left or right and customize quick actions for the care you record most often.

DARK MODE FOR NIGHTTIME CARE Use dark mode for those middle-of-the-night feeds and diaper changes. Choose light or dark appearance, or let Osca follow your device's system setting.

BREASTFEEDING & BOTTLE FEEDING Track breastfeeding sessions by side. Record formula or expressed milk, including how much you offered, how much was left and how much your baby drank.

SLEEP TRACKING Start a sleep session when your baby falls asleep and record when they wake. Review naps and nighttime sleep. Forgot to stop the timer? Edit the recorded times later.

DIAPER TRACKING Quickly log wet, dirty or mixed diapers. See changes alongside feeds and sleep in one easy-to-browse timeline.

WEIGHT, TEMPERATURE & MEDICINE Record weight measurements and follow changes from birth weight. Keep a temperature history and log medicine names and doses, with notes for the details you want to remember.

CONTRACTION TIMER Start before your baby's arrival with an expected baby profile. Time contractions and review their durations and intervals in recorded sessions.

CARE OVERVIEWS Review recorded sleep, feeding and diaper changes over the last 24 hours, 7 days or 30 days. Look back at sleep patterns, highlight important observations and share a care summary with the details you choose.
