It's on the Google play store. My brother said that my voice sounds weird, and not like a female's, it's probably more like a higher pitched boy. I know it isn't perfect, my pitch is high but I didn't think the rest of it was that bad. He is supportive of my transition though, so I think he was just trying to be helpful.
Anyways, I haven't had much luck (I haven't really stuck to it) with voice training. In the past I would always get discouraged because it never feels like I'm doing it right and my voice gets really weak at super high pitches. So, with the app VoiceUp, there's 3 stages, @ $15 a stage, which really isn't that bad because I can always revisit them, but I just don't know how much it'll actually help.
With the test, my voice is at 165 Hz, which is more in the female range. But I know there's more to it than just pitch.
