Lilo

Lilo is the record two parents keep together while a baby starts on solids. It runs a structured 7-week additive protocol — food groups introduced week by week — logging each meal with its ingredients, quantities and the baby’s reaction. Water and stool sit on the same timeline, because that’s what the appointment asks about. Reactions carry a severity, so a pattern is visible rather than remembered.

The engineering problem is the second parent. Both phones write to the same record, often at once, often offline in a kitchen. That’s a CloudKit shared-database model on top of SwiftData — real-time where the network allows, quietly convergent where it doesn’t.

A care lane runs alongside: medications, doctor visits and vaccinations, with reminders. A meal can be typed in plain language and parsed into ingredients on-device by Apple’s Foundation Models. Everything exports to CSV — the log leaves the app and reaches the person who needs to read it.
