I've been a premium user for quite a while, and I use Evernote quite extensively to sort my work notes. I use it on android devices - samsung tablet and samsung note.
Recently I was testing new ipads pro we might be getting from work and I was shocked. Why are we get a secondary experience on android?!
Handwriting has a significant delay(lag) even on samsung note 10, palm rejection is nonexisting and keyboard doesn't disaper when I'm adding a handwritten note. Not to mention no s-pen support -which I'm not sure is your fault.
Ipad experience is miles ahead, at least when it comes to handwriting. I know there is fewer devices to optimize for when it comes to Apple products but Android version of handwriting feels like it was made for those super old tablets with resistive touch screens and ghastly rubber styluses..
(Honestly It's not that terrible, just after having short apple experience I'm quite disappointed)
