# yuna: Baby Sleep Tracker — Feeding, Naps & Wake Windows > Feeding, Naps & Wake Windows (iPhone/iPad app by Aleyna Sonmez.) - Source: https://appshunter.io/ios/app/yuna-baby-sleep-tracker/id6805599417 (this page in markdown: same URL + `.md`) - Developer: [Aleyna Sonmez](https://appshunter.io/developer/6792901098) - Category: Health & Fitness, Lifestyle - Price: Free with in-app purchases - Age rating: 4+ - Requires: iOS 16.0 · 12 MB - Languages: American English, Czech, Danish, Dutch, Finnish, French (France), German (Germany), Greek, Hindi, Hungarian and 17 more - Released: 2026-10-21 - Data updated: 2026-10-29 ## What is yuna? 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, diapers 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 diapers. Answer them right in the notification, or get reminded again in 15 minutes. Feed and diaper 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 27 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. ABOUT SLEEP SOUNDS Keep them quiet — room volume, around 50 dB — and place the device away from the cot. The app links the study this recommendation is based on. yuna is not a medical device and does not replace advice from your pediatrician or midwife. FULL ACCESS Try yuna free for 7 days with the yearly plan. Cancel at least 24 hours before the trial ends and you pay nothing. Prefer to pay once? “Forever” is a one-time purchase that never expires — and if you have already paid for a year, switching to “Forever” costs only the difference. You can also look around first: the app includes a guided tour with sample data, no purchase needed. The yearly plan is charged to your Apple Account when the free trial ends, “Forever” at confirmation. The yearly plan renews automatically unless cancelled at least 24 hours before the end of the trial or the current period; manage or cancel it in your Apple Account settings.
