Google Camera

Google published recently to the Android store the Google Camera app (available on Google phones sometime ago).

Some features that caught my attention:
A sleek and simple user interface, a 360° photo mode and the blur mode (I am not referencing the panorama mode is something that I use frequently on my Samsung Camera software).

Only for these it was worth the download.

As a con: Reduced set of settings (no ISO, no setting for storage location)
