I like the Moment app, but I haven’t compared it to any others as I’ve been using it for years.

If you’re only interested in shooting raw, you probs won’t care, but one little bugbear is that it doesn’t get support the 3x optical zoom setting. It only presets to .5, x1 and x2. That’s the only thing that often bounces me back into the default app, I often prefer a 50-75mm kind of range, but for 48MP raw? It’ll be fine.
