Thanks for the quick response! I'm a bit far from the nearest Apple store, and even if I could go there, I wouldn't be able to test out Affinity Photo's ability to sync between the iPad and desktop versions.
Most iPhone (and Android) apps have a free version, even if it's a bare-bones, that at least allows a user to sample before buying. If I was able to try your iPad app in a free version, I'd know in three minutes if it could do what I wanted and I'd immediately purchase the full versions (iPad and computer).
That's just my two cents. Hope you can get a trial iPad version up so
