Syncry vs Flo

Flo Health
What Flo does well
Best-in-class cycle predictions, built on the category's largest dataset.
The most polished design in women's health, plus anonymous community chats.

Side by side

Built for
Flo
Her cycle first; the partner gets a read-only mirror tab.
Syncry
Both parents as co-authors, in a private family space.
Does it know you?
Flo
Deep cycle history; pregnancy content is by week, not by family.
Syncry
Iris remembers your family: your entries, moods and rhythms, week after week.
Privacy
Flo
Settled with the FTC in 2021 over health-data sharing; Mozilla still lists a warning.
Syncry
No ads, no shop, nothing sold. Your data stays your family's.
How far it goes
Flo
Pregnancy is a mode inside a cycle app; users report the free tier shows little more than how far along you are.
Syncry
One continuous journey, pregnancy to age 3. Nothing resets at the birth.
What remains
Flo
None; the subscription is the product.
Syncry
A printable family book that two voices wrote together, Sunday by Sunday.
Choose Flo if...
You mainly want cycle and fertility tracking with strong predictions.
Choose Syncry if...
You are pregnant and want these nine months accompanied, not upsold.

Flo monetizes your pregnancy. Syncry accompanies it.
