Rostik

Rostik is a baby tracker that draws your baby's whole day as a 24-hour clock face. Naps and night sleep appear as arcs, while feeds, diapers, baths and walks sit as marks around the rim, so one look shows how the day has gone, without scrolling through a list of timestamps.

Logging takes two taps and works one-handed: sleep, breastfeeding, bottle, solids, pumping, diapers, baths and walks. From the entries you have already made, Rostik estimates when the next nap is likely, using your own baby's pattern rather than a generic age chart.

Up to five people can share one diary (a partner, a grandparent, a nanny), each with their own role, and every entry shows who made it.

Other features:

• Weight, length and head circumference on WHO growth curves with percentiles
• Weekly and monthly trends for day sleep, night sleep, feeds and diapers
• White noise, rain, heartbeat and lullabies that keep playing with the screen off
• A reference shelf for parents: common childhood illnesses by age, the CDC immunization schedule with a checklist, and a dose reference based on the BNF for Children and the AAP. It is information for parents, not medical advice, and each screen names its sources.
• Works offline and syncs when back online; data is stored on servers in the EU

Every feature is open during a 7-day free trial. After that Rostik Pro is a monthly or yearly subscription that covers the whole family diary. No ads.

Available in English, Spanish, German, French, Italian, Portuguese, Russian, Ukrainian, Polish, Romanian and Turkish.
