I use Windows out of sheer commercial necessity (sigh,) and the enterprise version because it (alone in many instances) allows the removal or disabling of many, many "features" in W10. If or how my modifications to W10 Ent. affect the performance of Viking is something that I'm not prepared to speculate on.
I do use ExifToolGUI; it's more than adequate for many of my needs but in some cases use the command interface because it's more efficient.
As I reside in a rural area where cell phone service is, at very best poor, and often frequent areas where three is simply no signal available, the use of Android or iOS apps is not something that I've considered.
I had a short, but by no means exhaustive look this morning at some of the wrappers for ExifTool. A couple look as if they may be worth trying. Given the fate of Centos(7) where my database currently is, I'll be moving on, perhaps to Debian, in the near future.
