Log by typing or speaking: \"Nursed on the left side for 15 minutes\" becomes an entry with the side and the duration filled in.\n\nRHYTHM AT A GLANCE\nWake-up time, bedtime and the awake window, with the whole week on one timeline. Share a PDF sleep report with your pediatrician or sleep consultant.\n\nONE-TAP LOGGING\nTiles for sleep, breastfeeding (left and right side), bottle, food, diapers, walks, doctor visits, medications, vaccinations, symptoms, massage and custom events. Add a note or a photo to any entry.\n\nWIDGETS\nStart and stop the sleep timer from the Home Screen widget, and see the countdown to the next nap on your Lock Screen.\n\nBUILT FOR 3 A.M.\nDark mode. Entries save offline and sync when you're back online. Optional reminders before the next sleep window, never between 9 p.m. and 7 a.m.\n\nUP TO FOUR CHILDREN\nSwitch between children with one tap. Each has their own log, predictions and history.\n\nYour data stays yours: no ads, and we never sell it.\n\n---\n\nSUBSCRIPTION DETAILS\nLupibu requires a Lupibu Pro subscription, which includes sleep predictions, the AI assistant and the Rhythm tab.
