Halumo is a professional photo editor built natively for iPhone and iPad. It brings together a deep collection of nondestructive light and colour adjustments, one-tap AI selections that run entirely on your device, 39 photographer-designed presets, and an AI that turns a sentence into a full set of real, editable adjustments.
Everything you need to finish a photograph
• Edit with a complete collection of nondestructive adjustments — exposure, contrast, highlights, shadows, whites, blacks, temperature, and tint
• Shape contrast precisely with Tone Curves on RGB, Red, Green, and Blue
• Edit colour exactly with an eight-band Colour Mix, tuning the hue, saturation, and luminance of each band on its own
• Sharpen with radius and masking control, and reduce luminance and colour noise separately
• Add a vignette, correct chromatic aberration, and apply lens-distortion correction to RAW files
• Crop, straighten, rotate, and correct perspective
• Follow every change in a live Histogram
• Compare before and after with a split view, and step back through a compressed History and named Versions
Selections powered by AI
• Select the subject, the sky, or the background in a single tap
• Press and hold any object in the photograph to select just that object
• Add radial, linear, and brush masks, refine any selection by colour and luminance range, then invert, combine, and rename them freely
• Paint at any Strength, and see exactly what a mask covers as a tint on the photograph
• Every AI selection lands as an ordinary mask, editable with the same tools as one you drew by hand
