In a few years, people will surely shake their heads in disbelief at the fact that nowadays it has not been a matter of course to get a halfway professional remote app from the manufacturer with every camera.
However, these days all the more third party developers can be happy about this, in the case of Sony even a German Android developer named Steffen Conradt. Conradt is programming an independent remote app for Android smartphones, which supports numerous Sony cameras with surprisingly many functions.
Camoodoo - Remote App for Sony cameras
Camoodoo works not only for the photo mode, but also in the movie modes. And this with practically every halfway current Sony camera that supports WiFi. So not only DSLMs but also camcorders and many ActionCams.
We can't try out the app ourselves right now, but the promised features sound very exciting: Besides a Display LiveView (with frame guides and touch autofocus) there is access to many relevant camera settings.
For .99, the Pro "full version" will not only be free of displays, but also provide focus peaking, zebra and histogram. In addition, there will be color adjustments for the Liveview, which will include SLog 2/3 profiles in addition to contrast and saturation.
Camoodoo - Remote App for Sony cameras
If you read 
related comments in the Playstore, the biggest problem of the app seems to be that the internet connection in the smartphone cannot be used for other tasks at the same time. This is not so much due to the app, but to the principle of how Sony cameras can be "remote controlled".
All in all, it certainly sounds exciting for all Sony users who have missed a halfway professional remote app. Since you can also try the program for free, the hurdles for your own experiments are quite low.
