Other Which iPhone was the first to include an Altimeter?

[HappyDude20]

I know the Series 3 was the first Apple Watch to have a built in Altimeter but am wondering which iPhone model was the first to include an Altimeter?
Thank you!

The iPhone 6 was the first to include a barometer, if that's what you are referring to.
