## What is Moonbub?

Moonbub helps you track your baby's sleep and know exactly when they're ready for their next nap - using the same wake window science that premium apps charge for.

The difference? Moonbub is free. Completely, permanently free.

We built Moonbub because every parent of a newborn deserves good tools, not another subscription. No ads. No paywalls. No "premium" tier. Just a clean, thoughtful app that works.

FEATURES

- One-tap sleep timer for naps and nighttime
- Smart wake window tracking with color-coded zones (Sweet Spot, Tired, Overtired)
- Live countdown showing how long until baby's next nap
- Manual sleep entry for sessions you forgot to track
- Daily summary with total sleep, nap count, and longest stretch
- Sleep history organized by day with quick patterns at a glance
- Multiple baby profiles for siblings or twins
- Push notifications when wake windows are closing
- Secure account with email login and password reset

WAKE WINDOWS

Moonbub uses age-appropriate wake window ranges based on pediatric sleep research. As your baby grows, wake windows automatically adjust. The arc gauge shows you exactly where your baby is:

  Green = Too soon for a nap
  Yellow = Sweet spot - ideal time to start winding down
  Orange = Getting tired - put baby down soon
  Red = Overtired - baby may struggle to fall asleep

WHY FREE?

We believe sleep tracking shouldn't be a luxury. The first months with a baby are exhausting enough without worrying about subscription fees. Moonbub exists to support parents, not monetize them.

Moonbub is maintained with care and updated twice yearly where required to keep things running smoothly and adapt to the latest platform changes.

DESIGNED FOR TIRED EYES

Dark theme by default. Large touch targets. Minimal steps. Because at 3 AM, you need an app that just works.

Suitable for babies and toddlers aged 0-24 months.
