Hello and welcome to Business Daily. I'm Hannah Malayne. Today we're speaking to creator and co-founder of one of the first period tracking apps and the woman responsible for coining the phrase Femtech, Eda Tin.

It's possible you've heard of the app Clue.

It's been downloaded over 100 million times in 190 countries across the world.

Ida was born and raised in Copenhagen, and prior to co-founding the app Clue, she ran a motorcycle

So this was back just when the first iPhone came out and I thought, what if we could take out

our phones and it could tell us if this was a day we could get pregnant,
