Where Her Good Days is different
Menopause at the center
Clue moves its deeper analysis and advanced predictions into Clue Plus, at $9.99 a month or $39.99 a year in the US (App Store). In Her Good Days nothing sits behind a payment.
Clue's perimenopause mode lives inside a cycle tracker. Her Good Days is built the other way round: in perimenopause and menopause the + Log menu leads with hot flashes and brain fog, and the weekly check-in compares your sleep on nights with and without night sweats.
