Log feeds, diapers, sleep, growth, and pediatrician visits. Walk into every appointment prepared. Your data never leaves your iCloud.
Designed for one-handed logging in the middle of the night. Quietly powerful when you have a moment to look closer.
Say "4 oz bottle" or "wet diaper." Apple's on-device speech turns it into a log entry — no typing, no taps.
One tap turns the past two weeks into a one-page PDF — averages, trends, and your visit notes — ready to share at the appointment.
Spot your baby's rhythm: feeding intervals, longest sleep stretches, side preferences. All computed on device.
See when the next few feeds are likely to land based on the pattern Tumbly has learned.
Real-time CloudKit sharing. Both phones stay in sync without an account, password, or third-party server.
Track weight, length, head circumference, and pediatrician visit notes — all in one private, longitudinal record.
Tumbly doesn't have a server, an account system, or a tracker. Everything is yours, on your device and in your iCloud Drive — exactly the same way Notes and Reminders work.
