Logging

Log it in one tap.

Four taps cover a whole night, and none of them ask you to think.

One tap, even at 3am

Put down, asleep, awake, feed. No forms.

Live nap timer

Counts up while your baby is down. No math.

Bedtime and nap reminders

Stay on schedule without watching the clock.

Edit anything later

Fix a time or backfill a missed nap from the day view.

History

See the pattern.

Every log becomes a day-by-day timeline you can scan at a glance, plus charts that turn weeks of naps and night-wakes into a simple sleep score you can read half-asleep.

Your plan

A plan for tonight.

An age-based sleep plan walks you through a gentle, structured approach step by step. It tells you what tonight looks like, when to check in, and what changes next week.

Sleep Sanity is informational, not medical advice. Talk to your pediatrician before starting any sleep-training approach.

Household sync

Sleep is a team sport.

Each parent signs in with their own account, invites the other, and both phones show the same logs about a second apart. Whoever is on duty tonight has the whole picture.

Free, full stop.

No ads. No in-app purchases. No premium tier. Tracking your baby's sleep shouldn't be one more thing you pay for at 3am.
