— Summer 2026 —

everything happening in your child's world. finally visible.

Passively capture your child's entire day — language exposure, developmental signals, interaction quality — and surface it as a Parentese score, early detection flags, a strength profile, and daily coaching. Wear it. Forget it's there.

What Nurbl Finds

Three things most parents never learn about their child.

Strength Signal Amy · 2y 4m
99th
percentile · Spatial Reasoning

Children with Amy's spatial profile frequently excel in architecture, engineering, visual arts, and advanced mathematics. She's already showing the pattern at 2. This is not a coincidence — it's a signal worth amplifying right now.

How to accelerate →

Block play 20 min/day. Puzzles above age level. Rotate spatial vocabulary: behind, through, upside-down. Nurbl surfaces one new activity each week.

Interest Trajectory Ryan · 3y 1m
🚀 Space & rockets
mentioned 4× daily on average

Children who develop early domain obsessions — and whose environments are intentionally designed around them — show 2.3× faster advancement in that domain. Ryan's obsession is a signal. He might become an astrophysicist. Design his world accordingly.

12-week activity plan →

Star ceiling installation. Library: science biography section. Nightly "mission debrief." NASA Jr. kits. Ryan's world, wrapped around the thing he already loves.

Early Risk Flag Billy · 18m
3
early indicators · late language emergence
Reduced name response — 4 of last 7 days
Conversational turns below 18m baseline
Limited consonant variety in babbling

Most families reach formal evaluation at 3.5 years. You have time, data, and a head start. Nurbl tells you what to watch and what to do this week — not in 18 months.

How It Works

Passive capture. Continuous analysis. Specific signal.

01

Wear It

Parent glasses and child wristband run silently. No logging, no buttons. Audio, motion, and interaction patterns captured automatically — every day.

02

Nurbl Analyzes

Every signal compared daily against age-matched developmental baselines. 30-day trends, not single data points. The same rigor as a developmental assessment, running every day.

03

You Know First

Strengths surfaced. Risks flagged with specific indicators. Coaching delivered for the exact moment you're in. Not generic advice — signal built from your child's actual day.

The Hardware

Two options. Pick the one that suits your family.

Option 1 — For Your Child

Nurbl Wristband

Tracks every word your child hears and speaks throughout the day. Language exposure, vocabulary growth, and developmental milestones — benchmarked automatically.

  • Word exposure by hour, vocabulary range, and language milestones
  • Motion data: engagement quality, activity levels, rest patterns
  • Your child forgets it's there
or
Option 2 — For You

Nurbl Glasses

Visual and audio together. Sees your child's face while you interact — attention span, facial expressions, fidgeting, eye contact. Hears both sides of every conversation.

  • Facial engagement: eye contact, attention, and emotional cues
  • Conversational turns and Parentese score — the #1 predictor of language outcomes
  • Daily coaching grounded in what your child's face and words actually show

The first five years shape everything.
Now you can see them clearly.
