Biphasic Signal Pattern — Ava Bracelet?

I have been using the Ava Bracelet about 15 days. Today after syncing my data it basically confirmed ovulation! It said that most women with ovulatory cycles will experience a biphasic signal pattern during their cycle. Just curious if anybody is familiar and what’s it mean?!
