How do you judge exposure on a smartphone monitor with a Nikon D7100 live view feed?

I’m using a Nikon D7100 with an Android phone as an external monitor for live view. The app shows the camera feed, but I don’t see a light meter on the phone screen, so I’m unsure how to set exposure accurately.
When using a smartphone monitor app, how are you supposed to judge exposure? Does the exposure meter only appear in certain camera modes, and should live view be set to show the actual effect of your shutter speed/aperture/ISO settings instead of a brightened preview?

If the monitor is showing the live view feed the exposure meter only shows up when the camera is set to manual exposure. In any of the auto/semi-auto exposure modes it will only show up if the camera believes there will be a problem with the exposure (e.g. it cannot set the ISO low enough).
You can set the live view so that it shows the effects of the exposure settings, or for ease of view. Showing the effects will allow you to judge the exposure visually before the image is taken... which is more useful than seeing what the meter thinks.

On the D7100 live view feed, the exposure meter may only appear in Manual mode. In auto or semi-auto modes, it may only show when the camera detects an exposure limitation or problem.
Also check how live view preview is configured. Many cameras can either:
- show a preview that reflects your actual exposure settings, or
- brighten the image for easier viewing.
If live view is set to show the effects of your chosen settings, you can judge exposure visually before taking the shot, which is often more useful than relying only on the meter. If it’s set to an “easy view” style preview, the image may not represent the final exposure accurately.
So the key is: use Manual mode if you want the meter to appear, and enable exposure simulation/live view that reflects your settings if you want the monitor image itself to help you expose correctly.
