Log when your baby sleeps and wakes. Koa works out when the next sleep is coming, and reshapes the day every time it changes. Built by a tired parent too.
Koa exists because my daughter hit the four month sleep regression and our nights fell apart.
Every evening became the same fight. Rock her down, lower her into the crib, hold your breath, hear her cry before you reach the door. We stopped sleeping in shifts and started just not sleeping. And every sound through the night was a 3 am decision: go in and risk waking her fully, or wait and feel like the worst parent alive.
Koa is the app I wish we'd had.
You tell Koa when she falls asleep and when she wakes. One tap each. That is all it needs. From those two taps Koa works out when the next sleep is likely to come, and tells you before she is past it, because a baby put down at the right time goes down easier than the same baby twenty minutes late.
In the morning Koa hands you the night: how long she actually slept, how many times she woke, her longest stretch. Not a blur you half remember.
And when the nights stack up, Koa shows you the one thing every exhausted parent needs to know: whether it's actually getting better. Week over week, in your baby's real numbers. Koa starts from what babies her age usually do and shifts to what she actually does, so the times get more hers the longer you log.
