All the data Ivy tracks needs to be transferred into the IVY app by syncing the device. With the automatic syncing of your device, Ivy will transfer the data it collected up to that point as soon as the IVY app is opened.
The data Ivy tracks - your activity and sleep are visible on the Wellness screen within the app, as well as your cycle data, hydration, and meditation.
Every day as soon as you open the app, you will as well receive the Wellness report for the previous day so you can always keep track of your progress.
On the Readiness page, you can check your Readiness score for the day, as well as the information Ivy tracked about your Heart Rate including your Heart Rate information, Resting heart rate, Respiratory rate, Cardiac coherence, and your Temperature and its deviation from your baseline.
