— QUESTIONS PARENTS ASK —

Is baby sleep tracker Luli good for newborns?
Yes. Newborn tracker Luli is built for babies from day one. Wake window predictions and nap schedule guidance adjust automatically as your baby grows. The baby tracker newborn log captures every sleep, feed, and diaper from birth, making sleep cycle Luli the most complete newborn tracker for new parents.

What is a wake window and how does Luli calculate it?
A wake window is the ideal time a baby can stay awake between sleeps before overtiredness builds. Luli calculates it based on your baby's exact age and last logged sleep, then notifies you before the window closes — so you can start the wind-down routine at the right moment.

Is baby tracker newborn log a free?
Luli is free to download and use as a baby tracker, breastfeeding tracker, nap schedule organizer, diaper tracker, baby diary, and sleep monitor. Premium features are available for parents who want advanced analytics and personalized sleep coaching.

Does Luli help build a baby sleep schedule?
Yes. Luli builds a nap schedule around your baby's actual sleep patterns — not a generic template. As your baby grows, wake windows and sleep schedule adjust automatically. The result is a consistent baby sleep routine without a sleep coach.

Easy way to track my baby's sleep. I just wish I could use the note section to allow auto correct.

Changed review to 5 stars due to developers being so responsive. Love the app, only issue is that rough days change the nighttime sleep suggestion to be slightly unreasonable. (I know it's just a suggestion.) My little one skipped a nap today and it's suggesting I have them take a nap at 7 pm and go to bed at 12 am (wake time was 8:30 am). Thank you for this app, I use it everyday!
