What functionality would be in demand on a smartphone for photographers?

Question

Android

Hello!
Interested in what functionality photographers would need on a smartphone?
As a helper application, e.g.

Answer 1

A flashmeter / exposure meter / exposure meter / lightmeter for measuring exposure and, even better, white balance.

Answer 2

Using the smartphone's GPS module to automatically add coordinates to EXIF ​​photos.
Using a smartphone to display in real time the picture just taken and the ability to immediately process it (reduce, crop, compress, remove unnecessary data about the shot) and send (post) to various services.

Answer 3

I tell you how a photographer sometimes shoots on a mobile phone.
(I rarely carry a DSLR with me when I'm not at work, and there are no soap dishes and I don't need it)
1. Important: white balance settings. Probably, this is in all more or less modern smartphones, but there were also those that did not.
2. Most important: exposure compensation. Archaic thing! Even in top-end DSLRs, the exposure meter "on the machine" is not always right. What can we say about smartphones.
3. Quick (!) answer about coordinates. I even agree that in the background every half an hour (or configurable) there would be a check of the coordinates. But, when I take a photo with a mobile phone, I want to quickly write the location data to the exif.

Answer 4

I do not know for what purpose you are asking, but I just need the functionality of this program . Actually, I bought it for iOS and for Android and actively use it.
There is also such a topic, creating a walk track and loading this very track into Lightroom in order to automatically place on the map the photos taken by the DSLR that day. For this purpose, I used the GPS Trakker Light program for android, but it is not very convenient. You need a program that performs only this one function and nothing more. We turned on, we walk, we write a track, stop, save as, transfer to a computer. All.
There is also such a topic as shooting TimeLapse. The remote for my camera, which allows you to take a picture after a given period of time, costs 6,500 rubles. If there was such a program for Android, it would be cool. But here we must remember that the time-lapse is filmed for half an hour or an hour, the phone will send a command to the camera all this time ... whether the battery will run out.
