yuna: Baby Sleep Tracker

yuna turns the notes you already keep into something useful: the time your baby is likely to be ready for the next nap.

Every entry teaches it a little more. After a few days it knows your child's rhythm better than any table on the internet — because it learns from your baby, not from an average.

OPTIMIZED FOR iPhone Duo

Folded, the cover display shows the next nap at a glance. Unfolded in landscape, yuna opens like a book: the day’s ring on the left, every detail on the right. Upright, yuna uses the whole display. Folding and unfolding keeps everything where it was — even an entry you’ve started.

WHAT YUNA DOES

• Nap predictions to the minute, with wake windows that adapt as your child grows • One-tap logging for breastfeeding, bottle, solids, pumping, nappies and night wakings • Custom entries for your own routines — vitamin D, a walk, tummy time — with a reminder if you like • Gentle reminders for sleep, feeds and nappies. Answer them right in the notification, or get reminded again in 15 minutes. Feed and nappy reminders wait while your baby sleeps and arrive after waking. • Logged a little late? Change the time afterwards, or undo with one tap • Very short sleep? yuna asks whether it was a real nap or just a doze, so the prediction stays right • Statistics, growth curves and milestones • Home screen widgets: see the next nap, log an entry without opening the app • Sleep sounds — heartbeat, womb, gentle noise — with a timer that switches them off • In 10 languages

TOGETHER WITH YOUR PARTNER

Pair a second phone and you both log into the same day. Entries reach the other phone automatically — even a tap on the widget while your app is closed — and the widget there shows whether your baby is asleep, no matter who logged it. If you both log the same thing, yuna notices and asks which entry to keep.

YOUR DATA STAYS YOURS

There is no account and no sign-up. Everything lives on your device.

If you want to share with a partner, family sync sends your entries end-to-end encrypted between your own devices. The key is created on the devices themselves — we cannot read the data, and we cannot restore it either.

No tracking, no ads, no analytics.
