The Photographer s Ephemeris [b]3D version[/b] for archaeoastronomy: opinions? Is it accurate?

I use an app, the Photographer's ephemeris (TPE) for android - it's good for sunrise/sunset times and directions. Same for the moon.

They sent a new, 3D version, but this app is only for Iphones: they do not have an android version.

Anybody uses it?  Is it useful, accurate? (Particularly in Europe.)

(I have only android devices. If this 3D version is accurate for archaeoastronomy, I switch to an Iphone.)
