About this app

Cradlet is the baby tracker with a parenting coach inside it. Log sleep, feeds and diapers in two taps, then ask Luna anything and get an answer grounded in your own baby's data.

MEET LUNA
Ask "How did Charlie sleep this week?" or "Is 4 oz normal at 5 months?" Luna knows your baby's real timeline and answers thoughtfully, in real time, by voice or text. Health questions always point you back to your pediatrician. Luna supports you, never replaces your doctor.

TRACK EVERYTHING IN SECONDS
• Sleep tracker with a live timer, naps and night sleep
• Feeding tracker for breast, bottle and solids with amounts and sides
• Diaper log, medications, temperatures and symptoms as a simple health log
• Growth chart on WHO percentile curves
• Milestones, memories, vaccinations and appointments

UNDERSTAND THE PATTERNS
Wake windows, sleep trends and gentle insights that help you find a rhythm. A weekly recap you can share, and a PDF report your pediatrician will actually read.

BUILT FOR THE WHOLE FAMILY
Invite grandparents and caregivers with one code. Everyone logs to the same baby, and your subscription is shared.

SOOTHING SOUNDS
White noise, ocean waves and lullabies with a smart sleep timer.

PRIVATE BY DESIGN
Your baby's data belongs to you. No ads, no data selling. Delete your account and every record in one tap.

Cradlet was formerly Tiny Nest. Everyone gets 3 Luna questions a day; Cradlet Premium makes them unlimited. Plus and Premium unlock advanced analytics. Premium also unlocks family sharing. Terms: https://cradlet.com/terms Privacy: https://cradlet.com/privacy

What’s new

Multi-child improvements: every sleep and feeding timer shows the child's name, and stopping one child's timer never touches a sibling's. Fixed editing sleep and feeding times, including month-end dates. Larger text sizes now fit on Home, Sleep, Feeding and Reports. System Back works as expected on Android 16. Stability and privacy hardening
