And with the help of people on the internet.
A couple from NYC says they found out an important piece of data from a Fitbit: They are expecting their first child.
"I knew it was a possibility at any point," David said of his wife's pregnancy.
He asked that BuzzFeed News not use their last names as the couple is only about a month into the pregnancy and they haven't told many of their friends and family.
The dad-to-be said he also had another plan for the new year: getting in shape. So he received a Fitbit for Christmas with the hopes it would inspire him to become more active.
David said after he got the Fitbit, he discovered a Reddit forum where other users discussed their experiences with the product.
He started posting more frequently because he said everyone in the forum was very knowledgeable and nice.
"People were really cool [in there]," David said.
