BolaBabble - See your child's first words grow Capture the magic of your toddler learning to talk. BolaBabble listens during everyday moments - meals, bath time, play - and turns those snippets into a private, growing record of every new word, sentence, and milestone. What it does - Record naturally. Tap once. Talk, sing, read. BolaBabble transcribes on-device - your child's voice never leaves the phone for transcription. - Track real milestones. Vocabulary, mean length of utterance (MLU), turn-taking, tone variety, question-asking. Mapped to CDC and ASQ-3 language milestones from 12 to 60 months. - Voice ID for your child. Quick enrollment filters out adult speech so the stats reflect your child, not you. - First-word celebrations. Sticker book + confetti when a new word lands. - Play prompts. Age-tuned activities and conversation starters that pull more language out of toddlers without screen-staring. - Insights, not anxiety. See growth trends and gentle nudges - never a diagnosis. Flags worth-asking-the-pediatrician moments without alarm. Privacy first - Speech-to-text runs on-device. Audio never leaves the phone. - Audio clips stored locally on the device. - Optional cloud sync of transcripts, vocab, and milestones to your private Firebase account (encrypted in transit; audio never uploaded). - Sign in with Apple or Google. Email/password also supported. - Parental gate on Settings and account deletion. - No ads, no third-party trackers, no audio sold or shared. For parents, SLPs, early educators. Built for families who want a longitudinal picture of language growth between pediatrician visits. Not a medical device. Not a screening tool. A loving baby book with real signal. Requires iOS 18. Microphone and Speech Recognition access required.
