Firefly turns the moments you already share with your toddler — meals, bath, books, bedtime, the trip to the shops — into short, playful activities that build connection and communication. No training. No materials. No free hour required. WHAT YOU GET • 25 activities, each about five minutes, built into the routines you already have • One suggested activity a day, chosen for your child's age and what you told us matters • Simple steps, what to try if it feels hard, and what to try when you're ready for more • A place to jot what you noticed — twenty seconds is plenty • A gentle weekly plan. Miss a day and nothing scolds you • Guides on why the activities work, and how to ask for extra support if you want it BUILT FOR THE SKILLS THAT MATTER EARLY Looking and sharing attention. Taking turns. Copying sounds and actions. Pointing, waving, and first words. Every activity names the skill it builds and why it helps — before you decide whether to try it. YOUR CHILD'S DATA STAYS ON YOUR PHONE There is no account and no cloud. Your child's name, your notes, and your check-in answers never leave the device. Nothing about your child is sent to a server, ever. Export is free and always will be. Take your observations to a paediatrician or an early-intervention team as a PDF or a spreadsheet — prepared on your phone, uploaded nowhere. IN ENGLISH AND VIETNAMESE Switch language in Settings and every word changes: the activities and the guides, not just the buttons. WHAT FIREFLY IS NOT Firefly is an educational companion for families. It does not provide medical advice, diagnosis, screening, or treatment, and it is not a substitute for care from qualified professionals. Firefly never scores, rates, or measures your child.
