Deerly – Baby Tracker & Log
Feed, sleep, diapers—together
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Deerly is the baby log built for exhausted new parents—log with one hand, share with the whole family, or just say it out loud.
■ One-tap logging
Nursing timer, bottles, formula, diapers, sleep, solids, temperature, height and weight—30+ record types, with your favorites one thumb away.
■ Track together, in real time (free)
Invite your partner or grandparents. When someone logs a feed, everyone else sees it within seconds—no more "when was the last bottle?" texts. Every entry shows who logged it.
■ Log by voice
"120 ml and a dirty diaper"—one sentence becomes two records, no keyboard needed.
■ Watch & widgets: you don't even need your phone
Start a breastfeeding timer right on your Apple Watch — left side, right side, switch, pause, all from your wrist. No need to free up a hand while holding the baby. The Lock Screen widget shows how long since the last feed — no unlocking, no opening the app. The Home Screen widget logs sleep/wake with one tap, or jumps straight into voice entry.
■ Growth you can understand
Built-in WHO growth charts show exactly where your baby's height, weight and head circumference fall. Daily milk, sleep and diaper stats are charted automatically.
■ Photo & video diary
Capture the little moments and share them with your family.
■ About your baby's privacy
We don't think baby photos belong on someone else's server forever. Photos and videos are only relayed briefly over a secure connection between your family's devices, then deleted from our servers—the real copies live on your own phones.
■ Also included
- Multiple babies, kept separate
- Back-date, edit and delete—everything stays in sync
- Night mode for 3 AM feeds
