J. Matt,
You are definitely not the only photojournalist who needs this. I've been filing photos with mobile devices since 2003 and have used several platform and software combinations. I am currently using FSN Pro, that's an upgrade from Filterstorm Nue, because it supports IPTC templates. As you know, this is a must for fast filing. I use this app on iPad too, but it is best on iPhone. However, I am sure the app will be abandoned at some point and I watch whether Affinity Photo will support this with keen interest. Also, if I have to choose between iPad and iPhone, I choose iPhone hands down. The whole point is to not have to go sit down somewhere to file. If I have to do that, I might as well use a laptop.
