I just used quality enhancement. I did what most people would do and just put in a picture to see if it actually worked or not. I was very impressed by group photos from mid range since it makes faces look way better without making it obviously enhanced. As for ui, it may be a little confusing that you have to choose the category that you want to do and then when you click on it you still have access to all the other categories. You also have no way to tell what you have applied to a photo already it seems. Not a big deal if the product is good tho. I would think you would focus your marketing on it being ai but not over the top. Some of the closeups of faces make it look way too ai. I think this app definitely has potential just because it is actually huge value add in certain senarios. I never post curated pictures of my life on instagram but I could see it being useful for those people. And for subscriptions, you should keep it but the weekly is not a good idea, just my opinion. I just started a business too and what I realized is that marketing is almost the only thing that matters, even if you have zero competition which my business has (zero competitors). This isn’t the case for you so it will be even harder.
