Literally every single product image uses an iPhone, and the real product photo is also clearly an iPhone.
Just because it doesn't have a big image or text with OS compatibility does not mean you can't intelligently determine based on the product photos what OS it's for. If it were for Android, they'd have at least one Android photo, or specifically mention Android compatibility. If it's a completely iOS-centric page, you can guess /quite easily/ it's iOS only.
I don't know anyone with an iphone and rarely see pictures of them. As such, i simply am not familiar enough with them to figure out whether it's an android or iphone just by looking at it, especially since the UI is very generic and android mods and ISP OSes plentiful.
