Image Sync is an application that, when combined with supported cameras enables remote capture, image view, copying image to a mobile device, uploads to social media, and other functionality.
I downloaded this from the app store but it can also be found here :-

Unmentioned in this app description, I am able to control some of my K70 camera functions via my phone including zooming in and out by pinching my fingers together on my phone's screen (which displays the K70 live view via wireless connection)
Transfer/Delete of photos from my K70 to PC or my phone is easy and very fast. You can even transfer photos/vids straight to social media formats this way.
I recommend this for those interested in phone control of your camera.
This currently supports the following cameras :-
PENTAX K-1 Mark II / PENTAX K-1 / PENTAX KP / PENTAX K70 / PENTAX K-S2 / GR II / RICOH WG-M2
