Honestly, for this price, just get a good DLSR or a newer phone with the latest camera.

This camera does take great photos and the app gives you many more important controls over lighting, etc. than you would get on a typical smart phone camera.

The design of the standard-length lightning connector as the only way to mount the DxO ONE is physically incompatible with a significant percentage of popular phone cases

The phone and the app work perfectly together

No more do I have to rely on mediocre phone camera shots and hope to edit them so that they are somewhat presentable

OK, many people may try the Sony Qx-10 or some lens type smart phone camera, the thing I have to agree, since DxO is using lighting port, inkstand of Wifi,

so it won’t drain your phone or steal its storage.

For It's "selfie mode"You simply flip the attachment around to engage after the 3 sec countdown, then using your phone to more subtlety brighten your face for the shot

so it won’t drain your phone or steal its storage.
