It's 3am and the day is wrecked. Tell the coach in plain words — "move tonight 30 minutes earlier" — and today's naps and bedtime redraw themselves.
Baby Lodestar turns your baby's sleep into tomorrow's plan — and lets you change that plan by asking.
ONE TAP TO LOG
The main button on Today says asleep, then awake. That is the whole interaction. Times, type and notes stay editable afterwards, because at 3am correction beats precision.
THE PLAN IS THE SCHEDULE
Overnight, Lodestar drafts tomorrow's course and writes it straight onto your timeline — naps, wake windows and bedtime, drawn over the sleep you already logged. It arrives at the time you pick. There is nothing to accept and nothing to set up.
CHAT CHANGES THE DAY
"Push bedtime 30 minutes earlier." The coach edits today's course as you ask, and every change can be undone with a single tap. No forms, no confirmation dialogs.
GUIDANCE THAT STAYS IN THE BACKGROUND
Recommended total sleep, nap count and wake window for your baby's age sit next to what actually happened, so you can see the gap without being lectured about it.
WHERE THE NUMBERS COME FROM
Wake windows, nap counts and sleep totals are drawn from published sources, and every value is cited inside the app. Where the evidence is thin we say so: wake windows are a clinical rule of thumb, not a validated measure.
NO SIGN-UP
No email address, no password, no sign-in of any kind. The app creates an anonymous account for you on first launch. There is no analytics service, no advertising network and no tracking.
Your records are kept on our servers so a plan survives a reinstall, and drafting a course sends your baby's age and recent sleep to OpenAI, which runs the model. That is the only third party involved, and API data is not used to train models. Settings erases the account and everything in it, immediately.
BUILT FOR THE HOURS IT IS USED IN
Cream and clay through the day. Between 7 PM and 7 AM the app turns itself amber on near-black, so a 3am check does not start with a screen in your eyes — and you can pin that on or off in Settings. Large type, large targets, silent.
PLANS
Sleep logging, the day ribbon and the recommended ranges stay free forever. The nightly brief, the coach and the weekly report are $4.99 per week, $9.99 per month, or $59.99 per year, and a subscription covers a second caregiver at no extra cost. Start when the nights are hard and cancel when they are not.
Baby Lodestar is not medical advice and does not replace your pediatrician. If your baby has a fever, refuses to feed, or shows any other sign of illness, contact a health professional.
