Making Annotations

You can add up to five annotations on any frozen image. To add annotations during live imaging, tap the snowflake icon to freeze the image and display the annotation tools. 

Note that annotations are not available on cines, and annotations made in app cannot be edited once uploaded to Butterfly Cloud.
