Description by Markus Muller(from the App Store)
Luumi is the calm baby tracker made for tired parents. Log breastfeeding, bottles, pumping, sleep, diapers, growth, tummy time, temperature, milestones, and more in just a few taps—even at night and offline.
AI-POWERED CALM COMPASS When your baby cries, the Calm Compass walks you through gentle, age-aware options one step at a time. With your permission, Luumi considers age, recent sleep, feeding, diaper and tummy-time activity, plus what helped before. You always stay in control. Luumi is not a substitute for medical advice.
FAST TRACKING • Track left and right breastfeeding separately • Log bottles as breast milk or formula • Timers for pumping, sleep, and tummy time • Diapers, temperature, weight, height, and head circumference • Milestones, vaccinations, and checkups
UNDERSTAND PATTERNS Weekly comparisons and clear statistics reveal trends in sleep, feeding, and diapers. WHO growth charts help put measurements in context. Optional AI sleep analysis summarizes patterns in plain language.
CARE TOGETHER Share a baby profile with your partner or other caregivers. Updates stay in sync, while push notification choices remain individual for each device.
BUILT FOR 3 AM Large controls, calm colors, Night Mode, home screen widgets, and Live Activities help you finish quickly and get back to your baby.
PRIVACY Luumi is offline-first, ad-free, and uses an encrypted local database. Cloud data for the Luumi project is processed in Frankfurt, Germany. AI features run only after your explicit consent.
FREE & LUUMI PLUS Core tracking remains free. Luumi Plus adds features such as the Calm Compass, AI insights, WHO charts, widgets, PDF export, extended history, and additional caregivers or baby profiles. An optional seven-day in-app trial ends automatically and does not become a paid subscription. A paid annual subscription starts only after confirmation in the App Store and renews automatically until canceled.
