I bought Halide when it first came out. As a photography enthusiast, having trying out the app for a bit, I came to the conclusion that phone photography should be kept as simple as possible. While having advance options is great, the reason I carry a phone and not a camera on that certain occasion is because of its simplicity. I don't want to mess with aperture, exposure or focusing, etc. while on the go. If I wanted to do that I would bring my camera. So, yet I think there will be people who's excited for this kind of app, I see it has no use for me personally. It's a nice app though, and no doubt there will be people enjoying it, but the default iOS app does a good job for what I want.
The only reason I like Halide is because I loathe Apple's noise reduction in their photo processing. Shooting RAW is the only way to avoid it.
Every other aspect of computational photography is amazing, but when shooting photos I often intend to print, the photos just look so much nicer without noise reduction in my opinion. Everything close up becomes a smudgy mess.
