Logging
The whole night in four taps.
Every log is one big button. The app records the time, works out how long settling took, and keeps counting while you go back to bed.
Put down
Tap when your baby goes in the crib. Bub settles in with them.
Asleep
Tap when they drift off. Settling time is saved for you.
Wake up
Night wakes and feeds are one tap each. Morning closes the night.
Good morning
See the pattern. Plan the night.
Logs become a calendar, a score and a plan without you doing any of the math.
Tap any day, fix anything
The History calendar marks each night of the plan and everything you logged. Tap a day for the tickets, then edit or backfill anything.
87Last night
Sleep score
Night sleep, longest stretch, wakes and crying time, on one 0 to 100 scale. Set your own targets.
Bedtime and nap reminders
A bedtime nudge with a lead time you set, up to three nap reminders, and an optional Sunday summary.
Tonight is Night 6
The plan tells you what tonight looks like, when to check in, and what changes next week. Set a start date and the app keeps count.
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.
- Sign in with Google or Apple, only if you want sync
- One invite link, their own account, no shared password
- It still works fully with no account at all
Your plan
A gentle plan, one night at a time.
An age based plan with graduated check-ins. A consistent routine, put down awake, brief calm check-ins at intervals that grow. The app counts the intervals so you are not doing arithmetic in the dark.
- Most families start between 4 and 6 months, with their pediatrician on board
- A night feed weaning schedule for when you are ready
- The trend shows progress you cannot feel yet on night three
Questions
Straight answers.
The ones parents actually ask, about the app and about sleep training.
Is Sleep Sanity really free?
Yes. No ads, no in app purchases, no premium tier. Nothing is held back behind a paywall.
Do I need an account?
No. The app works fully without one. Sign in only if you want sync or a partner on the same logs.
Is sleep training safe?
Structured, age appropriate approaches with timed check-ins are widely used and studied. Your pediatrician is the right person to confirm it is a good fit for your baby.
Isn't letting my baby cry harmful?
This plan is not cry it out. You put your baby down awake and check in at set intervals, so they are never left indefinitely.
