That's kinda sloppy, mainly in the disclosure and translation department, but nothing that some updates won't solve.
I'm happy to support these devs with original ideas, even while they use some AI in a non-intrusive way. They have done something more important for in my book, which is following regional pricing.
It's stupid how several studios think charging my 3rd world country the same or even more than the US is a good idea. CDPR and bethesda think it's ok, but It's disgusting. I would rather support 11bit.
If you're deep into UI customization then iOS has never been and will never be the way. For me I've never cared that much about looks outside having dark mode, a clean interface and a wallpaper.
Some of the other things are possible though, like downloading app files from the store (they're IPA in Apple terms). Sideloading apps is also a thing, people have been using yt Vanced on iOS for years.
There's all kinds on browser extensions in the store, but only for Safari. There's almost no point in using any other browser in iOS since they all practically are Safari under the hood.
