Less nap math. More room to breathe. DozyDay is a simple baby sleep tracker built around wake windows. Record when your little one falls asleep or wakes up, keep their latest sleep entry close, and set a routine that fits your family. LOG SLEEP IN A FEW TAPS Track naps, bedtime and wake-ups. Adjust the time when you are logging after the moment, and edit your latest entry when plans change. MAKE WAKE WINDOWS EASIER Set your baby’s wake window, usual nap length, morning wake time and bedtime. DozyDay uses these settings and your sleep log to work out sleep reminder timing. Update the settings as your baby’s routine changes. SEE WHAT JUST HAPPENED Check whether your baby is awake or asleep and how long it has been. Find your latest sleep entry in the Latest tab, with more sleep history available with cloud storage. KEEP SLEEP STATUS CLOSE Live Activities keep sleep status at a glance on supported iPhones. OPTIONAL SUBSCRIPTION Start with sleep logging on your device. A subscription adds cloud storage, sleep reminders and sharing with another parent or caregiver. Reminders require notification permission. Built for the everyday question: “When did they last sleep?” Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://mostudios.app/privacy-policy
