Palm rejection for people who write with their wrists to the left of fingers

[drongobot]

I'm looking for a decent handwriting app. I would like to be able to rest my hand on the screen while I write with a stylus. Some apps come with a 'palm rejection' feature such as a wrist guard. This only works if the person writes with their wrist either below their fingers or above their fingers. Unfortunately, I am a lefty and I write with my wrist to the left of my fingers. Penultimate comes with palm rejection to account for this, but it's doesn't work (pen strokes are still registered, plus other problems).

Is there any good handwriting app with palm rejection technology for people who write with their wrist to the left of their fingers? I want to find out before buying any more handwriting apps.

Thanks
