# Bottles: Baby Tracker > Bottles: Baby Tracker (Bottles for short) is a baby-tracking app for parents and other caregivers. One tap logs a bottle feed, diaper or sleep at the usual amount and the current time, and logs sync between the phones of everyone who looks after the child. It is coming soon to Google Play for Android; an iPhone version is planned, without a date. It is not available to download yet. Trackers: bottle feeds (ml or oz), breastfeeding (a left/right timer that marks the side to use next), diapers (pee, poop or both; small, medium or large), sleep (start/stop), washes (bath or quick wash), weight (kg or lb), length (cm or inches) and temperature (°C or °F). Tapping a card logs the default; holding it opens a sheet to set the amount and a backdated time. Each log can be undone right away and edited or deleted later. Sharing: a child can be shared with other caregivers, such as a partner, grandparent or nanny, by QR code or invite link. Invites are single-use and expire after 7 days. Each log shows who made it, and a child’s owner can remove a caregiver at any time. Only a child’s caregivers can see that child’s data. Timeline and graphs: logs are listed per day with a daily summary and can be filtered by tracker. Graphs cover a sleep rhythm chart, daily sleep totals, bottle amounts, breastfeeding, diapers, washes, temperature, and weight and length on WHO growth percentiles (3rd to 97th). The app is not medical advice. Practicalities: logging works offline and syncs later. Several children can be tracked, one at a time. Dark mode follows the phone or can be set manually. Sign-in is with a Google account. The app is in English. The basic app is free to start, including sharing with another caregiver; paid plans for more caregivers and children may come later. Data is stored in the EU and is not sold. Support: hello@babybottles.app. Bottles the baby tracker is unrelated to the Linux app also called Bottles.
