IOS 9 beta testing- sketching in notes?

All other beta testers- is this feature only available on iPhone 6 or something? I have an iPod 5 and can't figure it out, it shows on the apple website that there should be a button but there's no button to sketch shown.
there's no low power mode option either.

The notes sketching is only available for the iPad and iPhone and the same for low power mode. It's likely that those features will come into play with the next generation iPod.
