Napper and Multibaby both help you get a handle on baby sleep, but they are built around different problems. Napper is a sleep-first app - wake windows, nap timing and schedule guidance, for one baby. Multibaby is a full tracker, where sleep, feeds, nappies and growth all live in one place - and it works whether you are raising one baby or several, giving each their own profile.
If you are tracking twins or two under two, the difference shows up on every screen. Here is how the two compare.

Where Napper fits
If you have one baby and your main question is "when should the next nap be?", a sleep-first app like Napper is focused and easy to live with. Its strength is nap timing and routine guidance.
Where Multibaby is different
Multibaby works for a single baby and is built to handle more than one. Every baby has their own profile, and you switch between them in a single tap. It is not sleep-only: bottle and nursing feeds, nappies, growth and milestones are all logged in the same place, so nothing lives in a second app.
- Say it, do not type it. Voice logging captures a 3am feed without turning on the light.
- Sees the day coming. On-device learning suggests the next nap, feed and bedtime for each baby.
- Private by design. That learning stays on your phone.
Frequently asked questions
Is Multibaby a good alternative to Napper?
If you want more than sleep tracking - feeds, nappies and growth in one app - and especially if you are tracking twins or close-in-age siblings, Multibaby covers more ground. If you only want nap timing for a single baby, a sleep-first app may be all you need.
Does Multibaby work for twins and multiples?
Yes. It is built for it. Each baby has their own profile and you switch between them with one tap, so two schedules never get tangled.
Can Multibaby track feeds and nappies, not just sleep?
Yes. Bottle feeds, nursing sessions, solids, nappies, growth and milestones are all logged alongside sleep.
Is my data private?
Yes. Multibaby's predictions are learned on your device, and that data stays on your phone.
