As I was looking at the initial data in the BloomSky app on my iPhone, I decided to try on my iPad.  The app installed but it wasn’t iPad native.  It has been many years since seeing an app do the 2x thing.

Later, on my iPhone, I tried to rotate to landscape and nothing happened.  Again, haven’t seen an app in a long time not support both orientation.

These aren’t deal breakers but just observations.
