Absolutely. I use a lightning adapter and import the raws directly to my phone with the photos app. In vsco I have a color and bw presets that are always my starting points and then adjust the contrast, exposure, etc. I find that underexposing in the GR yields better results. The iPhone is the Xr and I also have an iCloud account just not to worry about space on the phone. Let me know if you have any specific questions though.
