Solivie

Your baby's language journey

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Passive, on-device speech tracking for your baby. Daily vocal time, conversational turns, and milestones from 0–36 months. Audio never leaves your phone. Solivie passively listens for your baby's voice and turns the day's vocal activity into clear, evidence-based development insights — without ever uploading audio. Speech and conversation are the strongest known predictors of early language development. Solivie measures the three signals that actually matter — how much your baby vocalizes, how much speech they hear from caregivers nearby, and how often the two of you take real conversational turns — and tracks them quietly in the background. WHAT YOU GET • Daily Snapshot: Baby Voice minutes, Speech Around Baby minutes, and Conversational Turns, updated throughout the day. • 28-day, 3-month, and 1-year Trajectory charts so you can see your baby's own growth arc, not a comparison to other children. • Milestone Map from 0 to 36 months — Babbling, First Words, Two-Word Combos, Word Explosion, and beyond — with stage-specific tips for what to try this week. • Today's Tip: a short, evidence-grounded prompt picked for your baby's stage (story retelling, expand-and-extend, open questions, naming feelings). • Trend Cards: "growing," "steady," "below usual" — based on your baby's own baseline, not someone else's. • Notifications when a milestone is reached or a strong week shows up. PRIVACY YOU CAN VERIFY • All speech detection runs on the device. Audio is never uploaded — not for analytics, not for training, not ever. • Recordings library: short clips from moments your baby vocalized, stored on your phone only — never synced to our servers. • What the cloud sees: numerical features and counts you can inspect. You control whether even those sync. • Per-purpose consent: Cloud Backup and the optional Help Improve Solivie program are granted separately. • If you opt in to contribute anonymous learnings, we send only numerical class-probability scores and on-device acoustic features — never raw audio, never your voice — and we verify you're the parent through a Stripe card check ($0.50 charged then refunded), as required by COPPA's Verifiable Parental Consent rules. • Export everything you've collected as JSON, any time. • Delete your account and all baby data with one tap. We honor it server-side, not just locally. WHY IT MATTERS Longitudinal research on early language found that adult-baby conversational turns, more than passive talk, predicted vocabulary, brain activation, and verbal IQ years later. Solivie surfaces the metric that speech-pathology research keeps returning to — and puts it in your pocket. Your baby is talking to you whether or not you can quantify it. Solivie just helps you notice the patterns. WHO IT'S FOR • Parents of children 0–36 months • Caregivers who want a non-intrusive way to see whether their daily routines are on track • Families curious about language milestones without judgment or comparisons to other babies • Anyone preparing for a pediatrician check-up and wanting numbers to bring along PREMIUM (OPTIONAL) The free tier shows today's metrics and 28-day trends. Premium unlocks 3-month, 1-year, and all-time trajectories, the rolling 30-day Recordings library (clips kept on your phone only — never synced to our servers), and milestone deep-dives.

1.0.8 — Steadier background listening • Improved reliability when a phone call and other audio happen close together — for example, opening a video or music app right after a call now keeps Solivie listening in the background instead of stopping. • Continued background-monitoring polish for calls, voice messages, and music playing alongside Solivie.
