Not rude at all. Fair on both counts.

I could use a photo of Hamilton, but depending on grooming stage he veers between looking like a freshly clipped sheep or a scruffy mess. I'd have to grab him at exactly the right time. Plus I don't think I could get him to wear the headband.

If the free ones do what you need, then they would be great choices. I guess my target market is people who don't even know F-Droid exists, or would rather stick to the Play Store.

Plus none of those apps are dog-related.
