Abstruct - Wallpapers in 4K

I feel like these wallpapers are amazing, the app design is just as good, my experience is near perfect. This is the one time I would pay for wallpapers because I know they are high quality (In the app you can choose to download the whole wallpaper in its full resolution or make it crop to the exact size of your display), easy to download, there are absolutely no ads, and hundreds of wallpapers to choose from. I pay for pro but even if you don’t have pro there aren’t ads which make the experience impeccable. I would 100% buy this again and I often recommend this app to other people because it’s so good.

I had been using pro version in my android, which I got when it was available for one time purchase. Now that I switched to iOS, and know that it cannot be restored. Is there not even a way to get pro as a one time purchase? As I would like it better than a subscription model.

I used Abstruct on a Pixel until today (I am a Pro user) and I love the wallpapers. The colors are beautiful and the patterns are terrific. Several weeks ago I received a notice on my Pixel that the wallpapers would change automatically, an option I selected. Today I switched to an iPhone, the 13 Pro Max, and I don’t see the option to have the wallpapers change automatically. Am I missing that or is it not available on iPhone? Thanks.
