Thanks for the reply :)
Yeah, I guess there really is not much in the way of explanation. The Recipes site is very much a sort of springboard for the Beadifier app, to get users accustomed to the idea.
Payment plans is a big headache, to be honest. There seems to be no surefire way to do it. I went with a subscription plan because that seemed reasonable at the time. The free version is supposed to be fully featured enough to cater to most needs, though. I don't want to alienate those who are opposed to paying monthly, but I still want to keep that as an option so I can keep the lights on(!)
Auto aspect ratio is on my to-do list : )
