Hi Wang, thanks for your endeavors and the happiness you bring about. I really like this fantastic app. I suspect I would pay for it even if it provides the RGB curve editing solely. I noticed that you last updated the app two years ago then you just left it behind. I must say there may be no update need feature wise. But I believe you will do well to make it works smoothly with the coming iOS 15. Would help to make this app stay as long in ours phones? Thanks.

I think I can do most of this in Affinity - but no lesser application can touch it. Intuitive, powerful, and a very good value at the price. I’ll admit I had hoped for more from the layer portion of the app, wanting to be able to use it for double-exposure stuff - but I’m not criticizing! Not at this price and with all the things this app does so well. I’m a big fan of this developer, Focos and Focos Live. I would love to see an app from this developer that allows multi-layer overlays. If anyone can do it elegantly, powerfully, and at a reasonable one-time price, it’ll be this guy!

Great app

I love the app but was wondering if you could add an option to be able to adjust a selection of the photo instead of the whole photo?

Powerful, handy, versatile...

When I need quick color & value correction on my iPhone & iPad, this is my go-to. Curves are extremely powerful & flexible editing paradigms, and they're implemented really well here. Plus, this app's inclusion of (basic) non-curve HDR, grain, sharpness, layering, etc really rounds it out. While curves can also get tricky when you micromanage them with lots of points, MaxCurve's undo history, presets, (and the actual curves interface) keeps it easy to manage and re-think your edits on the fly. Highly recommended.
