    Any info on or way to figure out how many levels of pressure the new iPhone displays can sense? I imagine it's more than 3, since you can tweak the sensitivity of 3D touch.

    Yeah, that's why I asked if there was a way we could figure it out. Maybe it's in the dev documentation? Since 3D touch is available to devs?

    Maybe those that have already received their phone could answer? New Zeland already has their's and of course that one lady with the rose gold on Tuesday

    According to a review that I read the other day (I forget which), it's continuous, which is how it's adjustable. It can be demonstrated using the pen tool in Notes - thickness is adjusted by pressure, i.e. It's not binary.

    I believe the API gives back a float (floating point value) which goes from 1.0 to maximumPossibleForce which is a constant which varies from device to device. I didn't found a maximum force value for 6S/6S+.

    So basically that means, I think the developers can freely decide their pressure levels based on this float value.

    On top of this, there seems to be extra API for pop and peek as "special values".
