Try Captura I use it too. Its easy to work with.

For this tutorial you need tape and a phone.

First unlock your phone and start your recording app.

Then tape the phone to your head with the transparent tape.

Now you have a perfect recording device and for free (as long as you have a phone and tape)

I am recording everthing like this, if I play Vio or if I want to document my life!
