the same thing the desktop app does.
All of my photos are currently saved in a OneDrive folder. Currently, I have the desktop app scanning that folder, and the .ini file within that folder (and all the subfolders) holds the tag/face info.
A phone/tablet app should allow me to point to the same folder (since i also have OneDrive on my phone), be able to read the .ini files already in the folders, and then present it to me on my mobile device. More specifically, in the case of sharing photos with others, if they download both OneDrive and a Tonfotos app on on their phone/tablet, I could then share the Photos folder with them, which they could then point the TF app to.
A mobile app would also allow me to do my tagging on-the-go, as opposed to being “stuck” in front of my computer every time I want to update my photos with the TF program.
