we've been using the GS-RTK app on the CrystalSky screen. Don't know about other apps - there is work involved in organising the data to be stored this way so I suggest they may not (yet) do this.
The way the data is organised is the same as in the P4RTK: a separate folder for each mission, containing photos, raw GNSS observations (rinex formatted file), MRK file containing time, rtk positions, camera vs GPS offsets and some quality figures (rms, flag for fix/float solution). It should work with most cameras.
In RTK mode (via custom network or D-RTK2 base, same), the coordinates of the photos are RTK accuracy - and their RMS values are stored in the photo file, so that e.g. Agisoft can read the precision directly. Photos of RTK missions can go straight into Agisoft.
If RTK failed (or wasn't available) you can post-process the stored GNSS data in Klau PPK software (about US$2500) , and then send the photos with updated geotags to Agisoft.
With GS RTK it all works really sweet.
Two pain points, though:
1. in the custom network set-up , you must type in the name of the mountpoint manually. Any type and it doesn't work. All other apps I know you can pick the mountpoint from a pull down list.
2. The D-RTK2 base (in GS-RTK app) requires you to enter precise coordinates of the base antenna phase centre, not the marker on the ground, not the bottom of the antenna. Must enter in dd.ddd format.
All other software I know you enter the known coordinates of the survey marker, enter the height above marker (from marker to 'ARP' : either the underside of the antenna or a mark on the rim of the antenna) and thirdly either enter or select the antenna offset (offset is from ARP to antenna phase centre).
