Baby Activity Tracker That
Connects Play to Progress.
Lunara's baby activity tracker logs every tummy time session, bath, outdoor walk, playtime and more — tracking duration, frequency and daily totals automatically. The WHO recommends that infants under 1 year be physically active several times a day through interactive floor-based play, and that those not yet mobile be placed in tummy time for at least 30 minutes spread throughout the day. Lunara tracks progress toward these guidelines and connects activity data to sleep quality — so parents can see exactly how an active day shapes the night ahead.
🔒 Private by design · Shared in real time · WHO-guideline aware
What Activities Can You Track With Lunara?
Six categories, one timeline — every session timestamped and visible to every caregiver in your workspace.
Tummy Time
One-tap timer with daily total tracking. Lunara tracks progress toward the WHO-recommended 30 minutes per day and notifies caregivers when the daily goal is reached. Data feeds directly into the weekly activity insight.
🎯 Daily goal: 30 min (WHO)Bath Time
Log bath sessions with duration and time of day. Identify the bath-to-sleep pattern — many parents discover their baby settles faster after an evening bath. That pattern surfaces in the AI weekly insight.
💡 AI spots bath-sleep patternsOutdoor Walks
Log walks, park visits and outdoor time. Fresh air and natural light are proven to support circadian rhythm development in infants. Lunara tracks outdoor time and connects it to sleep onset time.
🌞 Tracks light exposure patternsPlaytime
Log interactive play sessions — floor play, toy exploration, peek-a-boo. The AAP recommends several interactive play sessions daily for infant development. Lunara tracks session count and total daily minutes.
📈 Connected to milestone progressStory Time
Log reading sessions by duration. Early literacy exposure is linked to language milestone development. Lunara connects story time logs to the baby's milestone tracker language timeline — so parents can see the impact of reading.
🔗 Linked to language milestonesCustom Activities
Add any activity not in the default list — music sessions, swimming class, sensory play, physio exercises. Custom activities appear in the daily timeline and are included in weekly AI analysis.
✏️ Add anything — fully customHow Does Tummy Time Tracking Work?
Tummy time is the single most evidence-backed activity for newborn development — the CDC and AAP both recommend starting from birth, building to 30 minutes spread across the day by 3 months.
Lunara makes it effortless:
- Tap "Start Tummy Time" — timer runs
- Tap to stop — session saved
- Daily total builds automatically
- Push notification to all caregivers when the 30-minute goal is reached
- Weekly AI insight shows tummy time trend and its effect on sleep
If the nanny did tummy time during the day, the parent sees the session in real time. If today's total is behind, the AI gently suggests when to fit in the next session.
Tummy time progress feeds directly into the milestone tracker development tracking.
How Does Activity Data Connect to Sleep and Milestones?
You Log Activities
Every tummy time, walk, bath and playtime session is logged with duration and time. No manual analysis needed — just tap and go.
Lunara Sees Patterns
Because Lunara tracks activity, sleep tracking, feeding and milestones in the same app, the AI sees connections across all four datasets simultaneously — something no single-purpose tracker can do.
Your Weekly Insight Explains It
Every Sunday, the AI weekly insight explains what the data means in plain language: "Aariv sleeps 28 minutes longer on days with 30+ minutes of active play." Included in Aariv's weekly report.
"Most baby apps log activity as a flat number. Lunara turns it into a pattern — and the pattern changes how you parent."

"I had no idea how much tummy time was affecting Aariv's sleep until Lunara showed me the pattern. Now I make sure he gets 30 minutes every day — and the nights are genuinely different."
"I was doing tummy time but had no idea if I was hitting the recommended amount. Lunara's daily goal ring made it something I actually track — like a little achievement to hit every day."
"Our physio gave us exercises to do twice a day. I log them as custom activities in Lunara and she reviews the frequency at every appointment. It's changed how productive our sessions are."

Tap to start the tummy time timer, tap to stop. Lunara logs the session duration, adds it to your daily total, and tracks progress toward the WHO-recommended 30 minutes per day. When Aariv reaches the daily goal, the app marks it complete — and the data feeds into his weekly activity insight.
