Filters are old news and just about every photo app has its fair share. It's doubtful anyone uses them except to try them out (then toss the image in the trash)
Why do iPhone image editing apps have to be so juvenile and limited?
Back in the 90s, (yeah a long time ago) Photoshop 4.0 could run just fine with 64 MB of ram on a 160mhz single core processor. Professional image editors who made a living with photo editing, used 200mhz machines with 128MB of ram to make Hollywood movie posters.
But here we are 25 years later with pocket computers (iPhone) that are more than 10X more powerful than those old machines --- and we get filter pack apps or extremely limited photo editing apps from other vendors.
Mind boggling

Ease of use, predominantly.
Full image editing on a <6.7" screen would be a nightmare, it would be next to impossible to have a useable tool selector and workspace concurrently displayed.
And secondly, the target market.
Photographers who take it seriously will always use their computers for editing, as you're more likely to catch flaws looking at a 27/34/49" 4K(8K)monitor than on a 6.7" screen, and theirs is a perfection game. Time is not as limiting a factor.
Instagram "influencers" want a jarring color scheme or big eyes, and they want it ASAP because their's is a content game. More content quickly means more likes.
