Lullo forecasts the next nap and bedtime from your baby's age and your own logs, so you can stop guessing and start winding down at the right moment.
Short naps, long bedtimes, 3 a.m. wake-ups. Lullo turns what you log into a plan that fits your baby's age and their own rhythm, and keeps adjusting as they grow.
Lullo starts from the wake windows, nap count and bedtime range that are typical for your baby's age.
Hold a single button when your baby falls asleep and again when they wake. Feeds and diapers go on the same timeline.
See the next sleep window and the whole day on one ring. Every nap moves the next one: a short nap brings the next sleep closer.
The more you log, the closer the plan follows your baby's own rhythm. Lullo shows how much of today's forecast already comes from your baby rather than from age norms.

One simple timeline for the whole day, quick enough to use with a baby on your arm.

Luna is an AI sleep helper that already knows your baby's age and logs, so you don't have to explain the whole week at 3 a.m.

White noise, rain, heartbeat and lullabies, made right on your phone, so they play without a connection.

The forecast is the centre. These are the things that make it easier to act on.

Lullo starts from the wake windows, number of naps and bedtime range that are typical for your baby's age. As you log, it pulls those numbers toward your baby's own rhythm, and every nap during the day moves the next one. A confidence score shows how far along it is: Learning in the first days, Adjusting after that, and In rhythm once it has about a week of logs.
From birth to 24 months. In the first two months, when sleep is still irregular, Lullo shows the next sleep window; the full-day forecast starts at around two months. You can also set Lullo up before the birth with a due date.
