According to the singing app, how many octaves do I have?

Hello my name is Jen, I'm 20 years old and I've always been interested in music. (Singing in particular). In middle school and high school, I always sang on the choir and I always was classified as a soprano. Today, I did this vocal warm-up on an iPhone app and I took a screen shot of my detected range. My question is, How many octaves do I have based on this singing app? The singing range is supposed to be the highlighted green section. I was unsure about my vocal range, so I just tapped the auto detect button. How many octaves does it look like I have based on this picture?

Here's the screenshot:
