Business Insider reported on aspects of the fertility device in 2022, when its codename was Project Tiberius.

The team was working to develop its own saliva collection device and mobile app, which could predict when a user might be in the fertile window. Users could also log their period symptoms, sexual activity and other data to assist with tracking their fertility. There are similar offerings on the market from companies including Inne, Oova, Ava and Mira, along with fertility and ovulation tracking apps such as Flo, Clue and Max Levchin's Glow.
