Measuring distance to subject: can mobile phone technology help?
Polar Bear:
As many of you will know I am all but as blind as a bat. The primary issue with my sight is no detail and that nothing is ever in focus. I see is shape, colour, contrast and shadow.
I have recently acquired a Bronica ETR Si 645 medium format camera and am currently experimenting. The biggest issue that I am having is of course I cannot tell when something is in focus. It's just how my sight is and it is a stark reminder of why I embraced autofocus so readily. I am of course estimating distance at the moment and setting the lens up considering distance and depth of field to help a little.
However, technology might be able to assist me with this, I hope. What I was wondering is, does anybody know of any apps (I am on Android) which will do a reasonable if not perfect job of measuring distance to subject please? I have done some digging but without much luck. Anybody here come across anything out there that might just do an adequate job please?

I know its not a mobile, but would a laser measure be of any help with this?
Polar Bear:
Hadn't thought of that. Would one work outdoors over a range of upto 20 metres?

Yes.
ETA - One issue you may have with it, if you are unable to see detail, is not being able to see where the red dot is.
Polar Bear:
Quite right. That will be an issue.
