A US mother has saved her daughter's life by using the Find My Friends app to rescue her from a car wreck.

North Carolina woman Catrina Alexander became worried for her 17-year-old daughter Macy Smith last week after she failed to return home and didn't answer her phone.

Smith had crashed her vehicle, flipping it multiple times down the side of a mountain. There, she lay trapped inside her car.

Using the Find My Friends app, which tracks people's movements, Alexander saw Smith's phone hadn't moved for several hours and drove out to the location.

"I can't explain watching the GPS on my phone with my dot for my phone getting close to hers and then suddenly seeing the tire tracks," she told WFMY.

Smith's family found her pinned underneath the car - but alive.

"Almost 24 hours ago I was lying in a ditch 20 yards off the road for the 7th hour with my arm pinned under my car," Smith wrote on Facebook.

"I will never forget the sound of my family calling out my name when they found me."

Emergency services were able to remove the teen from the car and take her to a hospital, where she was treated for a fractured neck and nerve damage.

"I wanted to share my story to encourage teenagers to get a tracking device on their phones," she wrote on Twitter.

"So to all parents and teenagers, PLEASE consider getting Life 360 or Find Friends as it could save your child's life like it did mine. I promise that it's worth it and if you layed [sic] hopelessly in a ditch for seven hours you would think so too."
