For parents, on iPhone and Android
Keep baby’s nights and naps together, noon to noon.
A diary for your baby’s sleep. Start the timer, note the wakeups. Come back to the details tomorrow.
Sleep logging and the timer are free.
At bedtime, start with a tap.
Choose night or nap, then start the timer. Pause it, resume it or enter the times by hand. The session stays available when you close the app.
Keep the little details, too.
How long a wakeup lasted, a feed, mood on waking: add what you noticed so you can return to it in the diary.
Noon to noon.
The whole night. The naps, too.
From noon to noon, your entries stay together. Totals exclude wakeups and count overlapping periods only once. Find each entry in the calendar and sleep grid.
Turn what you note into a diary to keep.
