For our sit, we communicated with the HO mostly via text since that was generally faster than using the THS app, so I might just be missing a feature that already exists. But if not:
I’d like to see a way to upload photos during the stay with an option to let the HO easily add that photo to their own profile. So if I take a great photo of their dog having fun with us, and I’m okay with it being on their profile forever, I can check a box indicating that. On the HO’s end, the next time they edit their profile or add new dates, it asks them if they’d like to add these photos to their profile. This way they don’t need to download/upload photos and it’s easier for the sitter to grant permission to use the photos. There should also be a checkbox to indicate that I want to add the photo to my profile.
