How Does Rubi Work?

Stretch Sensors Track Baby Movements using Nanotechnology

As your baby moves around during your third trimester, they cause ripples, vibrations, and many other types of forces that can be hard to keep track of when you are going about your day. Special stretch sensors can track unusual movement patterns and send alerts to your smart phone.

What are the benefits of Rubi?

Peace of Mind

Now you will know exactly when “you last felt the baby move.” Rubi collects data passively all day and sends information to your smart phone when you need it.

Closer Connection

Get to know the way your baby moves by getting updates to your smart phone.

Lower Anxiety

When you forget to count, Rubi has you covered.
