Wee HoursA newborn log built for 3am

Log a feed, diaper or nap in under three seconds, by voice, one tap, a widget, Siri, your watch or your glasses. Voice is understood on the iPhone; nothing is sent off to be interpreted.

Deployment

Every input, one log

Voice, buttons, widgets, Siri, Apple Watch and the Even Realities G2 + R1 ring all write the same typed, append-only event log, shared by both parents.

On-device voice

WhisperKit transcribes and Laya, a 0.4B decision model running through llama.cpp on the iPhone, scores predefined options. When it isn't sure, it asks you to pick with one tap.

Your agent, your answers

The app records facts; an MCP server lets your own AI assistant read and log them. No in-app advice, and no aggregation beyond the one-line status.

What's next, in one line

Every surface shows the same status, derived from the log by the same fixture-locked code in Swift and TypeScript:

Fed 2h40m ago · left next · diaper 1h10m ago

How it fits together

Local first. "Use without an account" keeps the household on the phone; signing in later uploads it, as a new household or into your partner's.
The glasses never run a model. Gestures write events directly; hold-to-speak uploads a capture that a household phone processes later, and two phones converge on the same result.
One spec. spec/ holds the event types, decision questions, calibration and fixtures that the Swift and TypeScript implementations both must pass.
