Monitor Your Baby's Growth, The Smart Way. We've designed the Beurer BY90 - so that parents can have ease of mind & can monitor & track their baby's growth & development at home, and have it all stored in their 'beurer BabyCare' app. The Beurer BY90 keeps you informed of the physical development of your baby with weight & height, thanks to the built-in tape measure. We've designed this scale to be comfortable for both the parent & baby - featuring an easy to read, large LCD display & a curved weighing platform. With the tare function, you can achieve accurate measurements while even putting the baby’s favorite blanket or toy on the scale to make it even more comfortable, & have less fuss. The scale has a weight capacity of 45 lbs & measures in 0.2 oz increments, for max. accuracy. The BY90 features a 10 memory capacity for tracking previous measurements over time. For more convenience, the scale syncs the measures values via Bluetooth to your smartphone. Beurer BabyCare App: The 'beurer BabyCare' app allows you to both monitor the development of your child's height and weight while also helping you to monitor your baby's development with other relevant information to log. Information such as behavior, food intake, or general health comments/notes. This allows you to keep track of your baby's physical health & behaviors all in one place and makes it easy to share with your pediatrician. *You can also use the baby scale without the app, if desired. For accurate readings, please wait to press the hold button until your baby or pet is as calm as they will be. Within 6 seconds, the word HOLD stops flashing and the average weight will be displayed. You can see more info on page 6 of the instruction manual and the full troubleshooting guide on page 8.
