MonBaby App is a free application that works with the MonBaby monitor sensor. It is designed for iPhone devices and requires Bluetooth 4.0 (Smart) support.

The MonBaby Smart Button is a wearable sensor that attaches to typical baby clothing. It tracks your child's movements and activity patterns, sending motion data to the parent's smartphone via Bluetooth Low Energy. With the MonBaby App, parents can view their baby's activity stats and receive alerts for important events detected by the application.

One useful feature is the ability to activate a sound alert when your baby rolls over, which can be helpful if you are concerned about your baby sleeping on their stomach.

It is important to note that the app requires the MonBaby Smart Button Monitor to function properly. However, there is a demo mode available that utilizes the internal accelerometer of the iPhone for testing purposes.
