Mi-labo Inc., a developer of municipal services, announced the launch of its maternal and child health handbook app 'mila-e Oyako Techo' in Tottori City on May 11, 2026. Rebranded locally as 'Tottori City Oyako Techo', the app aims to enhance support for child-rearing families. A key new feature is 'Myna Portal integration', allowing automatic synchronization of vaccination records without manual entry. Existing features like push notifications and vaccination schedulers remain available to support parents.
