Free, and it carries on after the birth
What to Expect is free because ads pay for it: its policy says Everyday Health shows ads in the app and may sell some online data to advertisers (What to Expect privacy policy).
Her Good Days is free too. Its pregnancy tools are practical: appointments with the questions you want to ask, a kick counter that shows how long it took, and a contraction timer with length and gap.
