not living up to its promises

The recipes look ok, but what seduced me with this app was the possibility of switching between metric and US measurement, which actually does not work (after switching in the general preferences, 1/2 cup remains 1/2 cup).
Maybe an update soon...?
Tried to reach the assistance website, which does not exist either...
