Finally understand
your baby.

Lua measures movement patterns, heart rate and skin temperature — the signals that together paint a picture of how your baby is really doing. From these, Lua learns your baby's personal rhythms: their calm, their restlessness, their sleep cycles. Think of it less like a sensor and more like a very attentive listener.

This was a deliberate choice. Lua was not designed as a medical monitoring system, but as a calm companion for parents in everyday life. Continuous oxygen monitoring in healthy babies can frequently lead to false alarms and unnecessary anxiety — especially at night. At the same time, there is currently no scientific evidence that such systems prevent sudden infant death in healthy babies. Lua therefore focuses on gentle support around sleep rhythms, comfort and routines — without constant medical alerts. Factors like sleep position, sleep environment and overheating remain deliberately in our focus. We continuously follow the latest research. Should scientifically sound methods meaningfully contribute to additional safety in the future, we will of course make these available to existing Lua users free of charge via update.

Lua is designed for babies from birth. The band is ultra-soft and adjustable — safe for even the tiniest newborn ankles. In fact, the newborn phase is exactly when parents feel most uncertain, and when Lua can help the most. 🌙

Yes — safety is everything to us. The band is made from breathable, skin-safe materials, free of harmful substances, and designed to stay comfortable even during long sleep stretches. It's lightweight enough that your baby won't even notice it's there.

Lua starts picking up patterns from day one — even its earliest insights are useful. But the real magic happens around day 7 to 14, when Lua begins to recognize your baby's personal rhythms. By week two, many parents tell us it feels like Lua just gets their baby. 🫶

The band records continuously — your phone just needs to sync when it's nearby. So even if you leave your phone in the other room (as you should — rest!), Lua catches up when you come back. Overnight insights are actually some of the most valuable ones.

Your baby's data belongs to you. We never share it with third parties — period. You can delete your data at any time. We believe privacy is a form of care — for your family and ours.

No — and that's intentional. Lua is not a medical monitor and doesn't diagnose anything. It's a parenting companion: warm, human, and designed to support your confidence — not to replace your doctor. If something feels wrong with your baby, always trust your instincts and seek medical advice. 💛
