Rytmi — Baby Diary

Rytmi is a shared baby diary: log what happened in a couple of taps and see the day's rhythm at a glance.

Version 2.0 is a ground-up rewrite for iPhone. A new interface built on Apple's own materials, a faster start, and noticeably calmer screens.

On the main screen you see: • the day as one arc, with what happened and what is expected on the same line; • when your baby last fed and slept; • the next nap and feeding with a time and a window; • which breast is next.

Log breastfeeding, bottles, naps, night sleep, diapers, measurements and milestones. A timer starts with one tap — left or right side, daytime or night sleep. Night sleep can be paused and resumed. Event types you do not use can be hidden.

Sleep and feeding can be recorded from the Home Screen widget and the Lock Screen without opening the app. A Live Activity shows the feeding or sleep in progress.

Analytics compare the last three full days with your baby's own baseline: total, daytime and night sleep, the wake window and the first nap. You also see what changed, how bedtime and waking usually go, and exact intervals across the period.

Invite parents, relatives or a nanny to one shared diary. A family can include up to five adults. Records are saved on the phone first, so the diary stays usable offline and syncs when the connection returns.

Rytmi has no advertising and does not use tracking. Diary content never goes to external analytics.

Important: forecasts are planning estimates, not medical advice. Contact a qualified healthcare professional about your child's health or development.
